From c6d92160f6d20d01b3774db492ecda1383cae5c1 Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Sun, 24 May 2026 06:52:58 +0000 Subject: [PATCH 001/152] Add Docker build for Blackwell that runs on any NVIDIA GPU host Adds a multi-stage Dockerfile producing an image that works on Ampere through Blackwell (sm_80 through sm_120: A100, RTX 30/40, H100, B100/B200, RTX 50-series, RTX 6000 Pro Blackwell). The build itself requires no GPU at all and runs on a free GitHub-hosted ubuntu-latest runner. How the GPU-less build works: 1. cu128 PyTorch wheels are fat binaries. torch._C._cuda_getArchFlags() returns 'sm_70 sm_75 sm_80 sm_86 sm_90 sm_100 sm_120' regardless of which GPU compiled the image, because the wheels are cross-compiled upstream by the PyTorch team. 2. All deps resolve in a single uv pip install pass with explicit pins (torch==2.10.0, --extra-index-url cu128, no --torch-backend=auto, no install.sh). This prevents the silent cu cascade where bitsandbytes' transitive cuda-toolkit==13 dep upgrades torch to 2.12+cu130 in a later resolver pass, leaving xformers and other cu128 wheels stranded. 3. Build-time verification uses package metadata (importlib.metadata.version) and the raw torch._C._cuda_getArchFlags() accessor. We deliberately avoid import unsloth at build time because unsloth.__init__ calls torch.cuda.get_device_properties(0), which requires an actual CUDA device and is not bypassable. Import-time correctness is exercised at deploy time by smoke_test.py with --gpus all. 4. UNSLOTH_COMPILE_DISABLE=1 and CUDA_VISIBLE_DEVICES="" during the build stage prevent any code path from JIT-compiling kernels for the build host's compute capability and baking the resulting cache into the image. The deploy GPU produces its own cache on first use. Other notes: - --index-strategy unsafe-best-match is needed because the PyTorch wheel index serves an old requests==2.28.1 that conflicts with datasets>=2.32.2, which the default first-index-wins strategy rejects. - Extra is cu128-ampere-torch2100 (ampere precedes the torch version in the pyproject ordering). - No flash-attn in the base image. FA3 is hard-refused on Blackwell upstream and unsloth gracefully falls back to xformers + SDPA. Users on Ampere / Ada / Hopper who want FA2 can pip install flash-attn on top. - Two stages: nvidia/cuda:12.8.1-cudnn-devel-ubuntu24.04 for the build, -cudnn-runtime for the deploy image. No nvcc in the published image. - A lockfile is emitted at /opt/unsloth-venv/requirements.lock.txt inside the image and can be extracted with docker/freeze.sh for byte-identical rebuilds even after PyPI moves on. CI workflow .github/workflows/docker-publish.yml: - Builds on ubuntu-latest on every push to main, every tag, weekly via cron, and manually via workflow_dispatch. Pushes to docker.io/unsloth/unsloth with cache via type=gha. - Optional smoke-test job runs on a self-hosted GPU runner if vars.HAS_GPU_RUNNER is set; skipped otherwise. End-to-end verification on sm_120 hardware is a nice-to-have, not a publish blocker. Validation: - Install path validated on a B200 host with CUDA_VISIBLE_DEVICES="" set (simulating the GPU-less CI runner): torch 2.10.0+cu128 holds, xformers 0.0.34, bitsandbytes 0.49.2, triton 3.6.0, transformers 5.5.0, trl 0.24.0, peft 0.19.1, accelerate 1.13.0. Arch flags include sm_100 and sm_120. - Runtime path validated end-to-end on B200: smoke_test.py imports unsloth, loads Llama-3.2-1B-Instruct-bnb-4bit in 4-bit, completes 5 LoRA steps with loss decreasing 4.11 -> 3.75. xformers fallback active as designed.

The entrypoint catches the three that cover ~95% of "it doesn't work" reports up front: 1. nvidia-smi inside the container sees no GPU -> user forgot --gpus all, or host is missing nvidia-container-toolkit -> entrypoint prints the exact docker run flag and the toolkit install URL 2. nvidia-smi works but torch.cuda.is_available() is False -> host driver is older than CUDA 12.8 supports -> entrypoint prints the minimum driver version per architecture 3. compute capability < sm_80 -> entrypoint prints the supported architecture table and exits Each check fails with a clear, actionable message rather than a stack trace. Set UNSLOTH_SKIP_GPU_CHECK=1 to bypass (for docs builds, offline tooling, CI). run.sh wraps `docker run` with the flags people most often forget: --gpus all (without it, the new entrypoint refuses to start) --ipc=host (DataLoader workers need >64MB shm) --ulimit memlock=-1 (NCCL + CUDA pinned host buffers) --ulimit stack=64MB (some torch kernels OOM the default 8MB stack) Plus it mounts the host HF cache + Triton JIT cache so model downloads and compiled kernels persist across container runs, and forwards HF_TOKEN / WANDB_API_KEY / UNSLOTH_LICENSE only when they are set on the host.

This used to surface as a confusing buildx failure mid-Block-2, but the actual problem is a host permissions issue that's settable up front. Detect by running 'docker info' and checking its exit code (not just grep on its output -- a permission failure prints to stderr and returns non-zero, so the old grep-based check was a silent skip). Also clarify the nvidia-runtime WARN: on Docker 28+ with CDI mode this is a false positive most of the time.

Turing GPUs work, with the caveat that bfloat16 is unavailable; the entrypoint prints a NOTE in that case so Unsloth's fp16 fallback isn't a surprise. --- docker/Dockerfile | 23 ++++++++++++++++++----- docker/entrypoint.sh | 31 ++++++++++++++++++++++--------- 2 files changed, 40 insertions(+), 14 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 7b5ce5c342..a62034d9f6 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -6,8 +6,11 @@ # * cu128 wheels are fat binaries: SASS for sm_80;86;89;90;100;120. # * Unsloth's runtime kernels are Triton, which JIT-compiles per device at first run. # * Anything that DOES need to be source-built (rare on this pin set) compiles -# against TORCH_CUDA_ARCH_LIST="10.0;12.0+PTX" -- the host GPU is irrelevant -# for compilation; nvcc emits whatever the arch list says. +# against TORCH_CUDA_ARCH_LIST="7.5;8.0;8.6;8.9;9.0;10.0;10.3;12.0;12.1+PTX", +# covering every current x86_64 NVIDIA compute capability per +# https://developer.nvidia.com/cuda/gpus. +# The host GPU is irrelevant for compilation; nvcc emits whatever the arch +# list says. # # Build host requirements: # * Docker with buildkit (default since 23.x) @@ -30,9 +33,19 @@ ENV DEBIAN_FRONTEND=noninteractive \ PIP_DISABLE_PIP_VERSION_CHECK=1 \ PYTHONDONTWRITEBYTECODE=1 \ PYTHONUNBUFFERED=1 \ - # Cross-compile for: Ampere, Ada, Hopper, B100/B200 (sm_100), RTX 50x / 6000 Pro (sm_120). - # +PTX on the highest arch lets future Blackwell SKUs run via JIT-PTX. - TORCH_CUDA_ARCH_LIST="8.0;8.6;8.9;9.0;10.0;12.0+PTX" \ + # Cross-compile for every current x86_64 NVIDIA arch per + # https://developer.nvidia.com/cuda/gpus: + # sm_75 Turing T4, RTX 20-series, Quadro RTX + # sm_80 Ampere DC A100, A30 + # sm_86 Ampere A40, RTX A6000, RTX 30-series + # sm_89 Ada L4, L40, L40S, RTX 40-series + # sm_90 Hopper H100, H200, GH200 + # sm_100 Blackwell DC B100, B200, GB200 + # sm_103 Blackwell DC B300, GB300 + # sm_120 Blackwell RTX 50-series, RTX PRO 6000 Blackwell + # sm_121 Blackwell GB10 (DGX Spark) + # +PTX on the highest lets future arch revisions run via JIT-PTX. + TORCH_CUDA_ARCH_LIST="7.5;8.0;8.6;8.9;9.0;10.0;10.3;12.0;12.1+PTX" \ MAX_JOBS=4 \ CUDA_HOME=/usr/local/cuda \ # Build-host-independence guards.

So we cannot do `docker push huggingface.co/user/repo:tag` for an Unsloth image.

Switching the arm64 leg from QEMU-on-amd64 to a native arm64 matrix runner is ~3x faster and avoids QEMU's occasional flakiness on long cu128 installs. The workflow now: * builds amd64 and arm64 in parallel on their native runners, pushing each as a single-arch image *by digest* (no tag) * stitches both digests into one multi-platform manifest in a follow-up `merge` job, using `docker buildx imagetools create` * keeps a separate buildx cache scope per platform to avoid cross-arch cache collisions Smoke-test job now needs `merge` (was `build`) so it only runs once the final manifest is published. Dockerfile header: replace the speculative aarch64 SASS list with the verified one from pytorch/pytorch v2.10.0 .ci/manywheel/build_cuda.sh (8.0;9.0;10.0;12.0 on aarch64), and note that sm_120 is forward-compatible to sm_121 per PyTorch maintainers -- which is what makes DGX Spark work without an explicit sm_121 SASS section in the wheel. setup_qemu.sh / test_locally.sh --platform stay in place: they're for the local-dev path on x86_64 boxes that don't have arm64 hardware. --- .github/workflows/docker-publish.yml | 170 +++++++++++++++++++-------- docker/Dockerfile | 7 +- 2 files changed, 126 insertions(+), 51 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 5b77ecbd7c..943d973c16 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -1,9 +1,10 @@ # Builds and publishes the Blackwell-compatible Unsloth Docker image. # -# The build runs on a free GitHub-hosted Ubuntu runner with NO GPU attached. +# The build runs on free GitHub-hosted Ubuntu runners with NO GPU attached. # This is possible because: # 1. cu128 PyTorch wheels are fat binaries -- they already ship sm_70 through -# sm_120 SASS, cross-compiled upstream by the PyTorch team. +# sm_120 SASS on amd64 (and sm_80;90;100;120 on aarch64), cross-compiled +# upstream by the PyTorch team. # 2.

BUT two CPU-side compilers shipped at cu12.8 do not know sm_121 and need a cu13 swap: (1) torch's bundled libnvrtc.so.12 from CUDA 12.8 rejects sm_121 as a --gpu-architecture. Symlinks libnvrtc.so.13 over it. (2) Triton's nvidia backend runs ptxas. Wheels older than 3.6.0 bundled cu12.8 ptxas which silently downgrades sm_121 to sm_80 (see triton-lang/triton#8335). Bump pin triton>=3.6.0 (3.6 bundles cu13 ptxas) AND install cuda-nvcc-13-0 so the entrypoint can point TRITON_PTXAS_PATH at it as defense in depth. Both fixes are arm64-only (gated on TARGETARCH, ~400 MB on the arm64 image; amd64 is untouched, no sm_121 hardware exists on x86_64). Neither component talks to libcuda, so this does NOT bump the toolkit driver floor away from cu128's 570+. TRITON_PTXAS_PATH is set from the entrypoint (only when the cu13 ptxas actually exists in the image) rather than via a Dockerfile ENV, because ENV is unconditional and Triton errors out if TRITON_PTXAS_PATH points at a nonexistent file.

Fix all four in this PR so the new Docker release path is self-consistent. 1. docker/smoke_test.py used `import xformers` unconditionally, which guarantees a failure on arm64 (built with `[huggingface]` extras to skip xformers since it has no aarch64 cu128 wheel). Wrap the import in try/except so the same smoke script validates both arches. 2. unsloth/_gpu_init.py forced `TORCHINDUCTOR_COMPILE_THREADS=1` before `import unsloth_zoo`, but `patch_torch_compile` in unsloth_zoo main pops that env var in non-debug mode. After unsloth_zoo init the guard was effectively undone, so cgroup-pinned `docker --gpus '"device=N"'` containers still spawned the Inductor subprocess pool that cannot enumerate the GPU. Set `torch._inductor.config. compile_threads = 1` directly post-import-torch and re-populate the env var so `determine_compile_threads()` in the zoo options dict also returns 1, regardless of whether the zoo-side fix from PR #694 has shipped yet. 3. docker-publish.yml UNSLOTH_REF build-arg defaulted to `'main'` for tag pushes and scheduled runs, so a `v1.2.3` release image would contain whatever `main` happened to be at build time, not v1.2.3. Pick the tag's `github.ref_name` for tag events and `github.sha` for branch/schedule events. 4. The smoke-test job pulled `:latest` regardless of which tag the merge job had just published, so tag/schedule/sha publishes were never actually validated. Re-run docker/metadata-action with the same config the merge job used, then smoke-test the first tag from its output. All four changes are gated and backwards-compatible. --- .github/workflows/docker-publish.yml | 36 ++++++++++++++++--- .../async_task_output_1rtbzl.md | 1 + .../async_task_output_1ud2z5.md | 1 +

Address the P1s + the regression-class P2s in this commit; the remaining nits are left for a follow-up cleanup pass. 1. unsloth/_gpu_init.py: the `NVIDIA_VISIBLE_DEVICES in os.environ` check triggered for every NVIDIA-runtime container including `--gpus all` (NVIDIA_VISIBLE_DEVICES=all is the default). Gate strictly on a non-special device list. Also drop the precondition that the env var was absent: if the user already pinned TORCHINDUCTOR_COMPILE_THREADS=1 we should still plant the UNSLOTH_FORCE_SINGLE_COMPILE_WORKER sentinel so the zoo-side patch knows to preserve the forcing. 2. unsloth/_gpu_init.py: after the post-`import unsloth_zoo` reassertion, monkey-patch `unsloth_zoo.temporary_patches.common.determine_compile_threads` to return 1, so any later `torch.compile` call that rebuilds the options dict still sees the single-worker forcing even if a downstream patch_torch_compile pops the env var again. 3. docker/Dockerfile: torchaudio==2.11.0 mismatched the torch==2.10.0 release pairing; pin to 2.10.0 so the ABI is correct and the audio stack matches torch/cu128. 4. docker/Dockerfile: drop `12.1+PTX` from TORCH_CUDA_ARCH_LIST. The cu128 toolkit compiler does not know about compute_121; the trailing PTX entry forced nvcc to emit a `sm_121` gencode that breaks any in-container source builds. 5. docker/smoke_test.py: the device-capability floor said `cap[0] < 8`, rejecting Turing (sm_75) while the Dockerfile + entrypoint advertise sm_75 as supported. Lower the smoke floor to sm_75 and print a hint that bf16 is not available on Turing. 6. docker/run.sh: `-it` is unconditional; CI / non-TTY invocations died with "the input device is not a TTY". Probe `[ -t 0 ] && [ -t 1 ]` first.

Stop leaking secrets via docker run -e VAR=VALUE argv (run.sh, test_locally.sh) `docker run ... -e HF_TOKEN=hf_xxx ...` puts the literal token in the docker CLI's argv, which is visible to any user on the host via `ps auxe` / `/proc//cmdline` for the lifetime of the process. Switch to the dash-only form `-e HF_TOKEN`, which tells docker to read the value from the parent shell's env and never appears in argv. Same fix for WANDB_API_KEY and UNSLOTH_LICENSE in run.sh and HF_TOKEN in test_locally.sh. 2. Stop stripping numpy/tests/ in the runtime layer (Dockerfile) The Dockerfile explicitly upgrades numpy >= 2.4 because numpy 2.2.6 shipped a stripped wheel where `from numpy._core.tests._natype import pd_NA` fails. Numpy 2.4 restores `numpy/_core/tests/`, then the existing `find ${VENV} -name tests -exec rm -rf {} +` deleted it again -- re-introducing the same broken-import state on the deployed image (the build-time verification at line 220 runs BEFORE the strip so it passed). Whitelist numpy's tests directories from the strip; keep stripping the rest. 3. Align :latest tag gate between merge and smoke-test jobs (.github/workflows/docker-publish.yml) merge job: enable = is-default-branch AND unsloth_ref == '' smoke-test job: enable = is_default_branch only On `workflow_dispatch`, `github.event.inputs.unsloth_ref` defaults to "main" (not ""), so the merge step skipped `:latest` but the smoke step still emitted `:latest` as tags[0]. The smoke step then `docker pull`-ed a prior `:latest` from Docker Hub instead of the image just merged -- so the smoke test verified the OLD image, not the new one. Copy the merge step's exact `enable=` expression into the smoke-test step so the two stay byte-identical and a workflow_ dispatch run validates whatever was actually merged. --- .github/workflows/docker-publish.yml | 9 ++++++++- docker/Dockerfile | 14 +++++++++++++- docker/run.sh | 11 ++++++++--- docker/test_locally.sh | 5 ++++- 4 files changed, 33 insertions(+), 6 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index eee1961fd6..e2ecaac199 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -216,13 +216,20 @@ jobs: # Re-compute the tag list deterministically from the same metadata-action # config the merge job used, so tag/schedule/SHA runs pull the image # they just published instead of an unrelated `:latest` from a prior run. + # IMPORTANT: keep this `enable=` expression byte-identical to the merge + # job's :latest gate above.

Both violate the image's build-host-independence rule. fetch_llama_prebuilt.py pins by build target only: amd64 takes the linux-x64-cuda12-portable bundle, arm64 the linux-arm64-cuda13-portable bundle (DGX Spark / Grace), both sha256-verified against the release's llama-prebuilt-sha256.json. convert_hf_to_gguf.py plus gguf-py/ are hydrated from the same release's source tarball so the converter's tensor mappings match the binaries, mirroring unsloth_zoo's _hydrate_converter_sources layout. LLAMA_PREBUILT_TAG build-arg overrides the pinned release. docker_confirm.sh: one-command confirmation script for any machine (Linux / WSL2 / macOS) following the staging confirm-script conventions: host + docker + GPU detection with CPU-mode auto-fallback, image pulls, in-container torch.cuda check, 5-step LoRA training smoke, baked llama.cpp verification, full-image boot probing Studio /api/health and JupyterLab /api, PASS/WARN/FAIL summary with RESULT line. --- .github/workflows/docker-publish.yml | 5 - docker/Dockerfile | 51 +++--- docker/docker_confirm.sh | 236 +++++++++++++++++++++++++++ docker/fetch_llama_prebuilt.py | 142 ++++++++++++++++ 4 files changed, 400 insertions(+), 34 deletions(-) create mode 100644 docker/docker_confirm.sh create mode 100644 docker/fetch_llama_prebuilt.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 417d0d6870..b4b174e468 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -124,11 +124,6 @@ jobs: cache-from: type=gha,scope=build-${{ matrix.platform }} cache-to: type=gha,scope=build-${{ matrix.platform }},mode=max outputs: type=image,name=${{ env.REGISTRY }}/${{ env.IMAGE_NAME }},push-by-digest=true,name-canonical=true,push=true - # The llama.cpp prebuilt bake reads GITHUB_TOKEN (BuildKit secret, - # never a layer) so the resolver's GitHub API calls are not subject - # to the anonymous per-IP rate limit shared across Actions runners. - secrets: | - github_token=${{ github.token }} build-args: | CUDA_VERSION=12.8.1 UBUNTU_VERSION=24.04 diff --git a/docker/Dockerfile b/docker/Dockerfile index 6e943f470c..c1af9baa4c 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -423,38 +423,31 @@ RUN if [ "${TARGETARCH:-amd64}" = "arm64" ]; then \ # Prebuilt llama.cpp so GGUF export works out of the box. # # unsloth_zoo's save_pretrained_gguf() calls check_llama_cpp(), which looks -# for llama-quantize + convert_hf_to_gguf.py in $UNSLOTH_LLAMA_CPP_PATH -# (default ~/.unsloth/llama.cpp).

The dir is the image's baked prebuilt, provisioned exclusively for Studio, so write the .unsloth-studio-owned marker next to the binaries. 2. With no GPU and no nvidia-smi in the build container, install.sh fell back to cu126 torch wheels for the Studio venv (and would pick cpu wheels on a CI runner without /proc/driver/nvidia), so the published image's Studio venv would depend on which host built it and could not train on Blackwell. get_torch_index_url now honours an explicit UNSLOTH_TORCH_INDEX_FAMILY override naming the index leaf (cu128, cu130, rocm7.2, cpu, ...).

The pip ninja lives in the venv bin, which subprocesses like vllm serve do not always inherit on PATH, so the JIT failed with exit 127. Install ninja-build so the binary is reachable from any PATH. 2. With ninja present the JIT still cannot succeed for device code: the runtime image deliberately ships no nvcc. Bake flashinfer-jit-cache (cu128) so ops missing from the cubin package (fmha_gen on sm_100a was the repro) come precompiled. In-process GRPO never hit this because unsloth-zoo blocks the FlashInfer JIT path; standalone vllm serve gets no zoo patches.

Three traps, all defended: From aba16af123d8fdedfb781203bb5bf2f085d20fc0 Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Mon, 15 Jun 2026 03:13:16 +0000 Subject: [PATCH 073/152] docker: notebook deps, image size cuts, per-notebook transformers Notebook dependency coverage (base Dockerfile): - Bake omegaconf, einx, librosa, decord, ftfy so the TTS/STT and vision notebooks stop dying on a silent No module named X. Installed in the notebook-deps layer (after the torch/vLLM resolve) with an assertion that the resolve did not move torch 2.10.0 / numpy>=2.3 / numba>=0.65. Image size (no functional change): - Base: prune npp to the two libs torchcodec actually dlopens (libnppicc + libnppc), drop link-time-only .a archives and the nvshmem device bitcode. Headers (torch/include etc) are kept so causal-conv1d / mamba-ssm still build at notebook time with --no-build-isolation. - Studio: pin the Studio venv to Python 3.12 (matches base) so its nvidia-*-cu12 wheels are byte-identical to the base venv's, then symlink the heavy arch-independent CUDA libs (cudnn/cublas/nccl/...) into the base venv copy. cuda_nvrtc and cuda_runtime are excluded (the arm64 nvrtc swap mutates nvrtc in place). Also remove the build-only frontend node_modules (runtime serves the committed dist). Studio image drops ~4.8GB. Per-notebook transformers version, run notebooks unchanged: - Bake coherent transformers sidecars (4.57.6 default + 5.3.0/5.5.0/5.10.2), each transformers==X with its matched huggingface_hub/tokenizers/ safetensors installed --no-deps into its own dir. Companion versions are resolved at build time so they satisfy each transformers' requirements. - unsloth_nb_compat.py: pick the sidecar from the notebook's pin or the model name and activate it (prepend to sys.path) before any ML import, without touching the base cu128 torch/vLLM/unsloth stack. - pip/uv shim on PATH: a notebook install cell becomes safe and idempotent inside a kernel (keeps the baked stack, records the requested transformers for its sidecar); passthrough to the real tool everywhere else. - IPython startup hook for manual JupyterLab, and unsloth-run for the headless driven path. --- docker/.dockerignore | 4 + docker/Dockerfile | 98 ++++++++++++++++++++- docker/Dockerfile.studio | 35 +++++++- docker/unsloth_ipython_startup.py | 18 ++++ docker/unsloth_nb_compat.py | 135 +++++++++++++++++++++++++++++ docker/unsloth_pip_shim.py | 136 ++++++++++++++++++++++++++++++ docker/unsloth_run.py | 107 +++++++++++++++++++++++ 7 files changed, 528 insertions(+), 5 deletions(-) create mode 100644 docker/unsloth_ipython_startup.py create mode 100644 docker/unsloth_nb_compat.py create mode 100644 docker/unsloth_pip_shim.py create mode 100644 docker/unsloth_run.py diff --git a/docker/.dockerignore b/docker/.dockerignore index ae1f499a29..1bd005c9c1 100644 --- a/docker/.dockerignore +++ b/docker/.dockerignore @@ -5,3 +5,7 @@ !fetch_llama_prebuilt.py !supervisord.conf !studio_launch.sh +!unsloth_nb_compat.py +!unsloth_pip_shim.py +!unsloth_ipython_startup.py +!unsloth_run.py diff --git a/docker/Dockerfile b/docker/Dockerfile index 2d577d0559..fd3a8d1cdc 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -282,10 +282,20 @@ RUN set -eux \ # langid DeepSeek-R1 GRPO reward's language-id check # easydict some vision trust_remote_code modeling files # protobuf slow->fast tokenizer conversion for sentencepiece models +# omegaconf TTS families + both NeMo-Gym RL notebooks' config objects +# einx TTS codec tensor-rearrange (Llasa / Oute / Spark TTS) +# librosa Whisper audio feature extraction (pairs with soundfile + torchcodec) +# decord ERNIE-VL vision notebook video decode +# ftfy Oute TTS text normalisation +# librosa pulls numba/soxr/audioread; numba is already pinned >=0.65 (numpy 2.4 +# compatible) by the vLLM pass, so the resolve must NOT move torch/numpy/numba -- +# the assertion below fails the build loudly if it did.

We record the content hash of every file we write; on refresh a file whose hash differs from what we last wrote is treated as user-modified and is left untouched, so the refresh only updates files the user has not changed and adds new ones. It never overwrites an edited notebook and never produces merge conflicts. Verified: an edited notebook stays the user's version across repeated upstream changes. - Fully best-effort and gated: UNSLOTH_SKIP_NOTEBOOK_SYNC=1 disables it, UNSLOTH_SKIP_NOTEBOOK_REFRESH=1 keeps the baked copy and never hits the network.

Dynamically follow the newest unslothai/llama.cpp release. build.sh resolves the latest release tag (following the /releases/latest redirect, no API token) to a concrete tag and passes it as LLAMA_PREBUILT_TAG, so the layer cache busts only when upstream publishes. The Dockerfile default is now "latest" and fetch_llama_prebuilt.py resolves it the same way, so a plain `docker build .` also tracks latest. Pin LLAMA_PREBUILT_TAG to a concrete tag for a reproducible, frozen build. 2. Make the in-app "newer llama.cpp available" banner work inside the image. Studio's freshness check (utils.llama_cpp_freshness.check_prebuilt_freshness) keys off tag / release_tag / published_repo in UNSLOTH_PREBUILT_INFO.json -- the schema install_llama_prebuilt.py writes. The image bakes the bundle directly, so the marker was the release tarball's own, which only carries upstream_tag / source_repo; the freshness check then bailed with installed_tag=None and could never report "behind", hiding the banner. fetch_llama_prebuilt.py now augments the baked marker with those keys (setdefault, no build timestamp so the layer stays byte-identical). A fresh build is on latest -> no banner; once upstream publishes a newer release the banner appears, as verified against the real freshness backend. --- docker/Dockerfile | 7 ++++- docker/build.sh | 21 ++++++++++++++ docker/fetch_llama_prebuilt.py | 50 +++++++++++++++++++++++++++++++++- 3 files changed, 76 insertions(+), 2 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 1dca2799e1..70c910ab1e 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -617,7 +617,12 @@ RUN set -eux \ # so the python-side tensor mappings match the binaries # /opt (not /root) so the install survives a `docker run --user` override; # UNSLOTH_LLAMA_CPP_PATH makes zoo find it regardless of $HOME. -ARG LLAMA_PREBUILT_TAG=b9596-mix-e6f2453 +# Default "latest" -> fetch_llama_prebuilt.py resolves the newest +# unslothai/llama.cpp release at build time (follows the /releases/latest +# redirect, no API token). build.sh resolves this to a concrete tag before +# invoking docker build so the layer cache busts only when upstream publishes; +# pass --build-arg LLAMA_PREBUILT_TAG= for a frozen, reproducible build. +ARG LLAMA_PREBUILT_TAG=latest COPY fetch_llama_prebuilt.py /tmp/fetch_llama_prebuilt.py RUN /opt/unsloth-venv/bin/python /tmp/fetch_llama_prebuilt.py \ "${LLAMA_PREBUILT_TAG}" "${TARGETARCH:-amd64}" /opt/unsloth/llama.cpp \ diff --git a/docker/build.sh b/docker/build.sh index 592a52da49..f84aa9f36e 100755 --- a/docker/build.sh +++ b/docker/build.sh @@ -18,10 +18,30 @@ PYTHON_VERSION="${PYTHON_VERSION:-3.12}" UNSLOTH_REF="${UNSLOTH_REF:-main}" UNSLOTH_ZOO_REF="${UNSLOTH_ZOO_REF:-main}" +# llama.cpp prebuilt: default to the newest unslothai/llama.cpp release, resolved +# here to a concrete tag so the build-arg changes only when upstream publishes a +# new release (correct Docker layer caching) and the build stays reproducible. +# Pin it explicitly for a frozen build: LLAMA_PREBUILT_TAG=b9596-mix-e6f2453 ./build.sh +resolve_latest_llama_tag() { + curl -fsSL -o /dev/null -w '%{url_effective}' \ + "https://github.com/unslothai/llama.cpp/releases/latest" 2>/dev/null \ + | sed -n 's#.*/releases/tag/##p' +} +if [ -z "${LLAMA_PREBUILT_TAG:-}" ]; then + LLAMA_PREBUILT_TAG="$(resolve_latest_llama_tag || true)" + if [ -n "$LLAMA_PREBUILT_TAG" ]; then + echo "Resolved latest llama.cpp release: ${LLAMA_PREBUILT_TAG}" + else + LLAMA_PREBUILT_TAG="latest" + echo "Could not resolve latest llama.cpp tag here; passing 'latest' (resolved inside the build)" + fi +fi + echo "Building ${IMAGE_NAME}:${TAG}" echo " CUDA ${CUDA_VERSION} Ubuntu ${UBUNTU_VERSION} Python ${PYTHON_VERSION}" echo " unsloth @${UNSLOTH_REF}" echo " unsloth-zoo @${UNSLOTH_ZOO_REF}" +echo " llama.cpp ${LLAMA_PREBUILT_TAG}" echo " arch list 8.0;8.6;8.9;9.0;10.0;12.0+PTX" echo @@ -32,6 +52,7 @@ DOCKER_BUILDKIT=1 docker build \ --build-arg PYTHON_VERSION="${PYTHON_VERSION}" \ --build-arg UNSLOTH_REF="${UNSLOTH_REF}" \ --build-arg UNSLOTH_ZOO_REF="${UNSLOTH_ZOO_REF}" \ + --build-arg LLAMA_PREBUILT_TAG="${LLAMA_PREBUILT_TAG}" \ -t "${IMAGE_NAME}:${TAG}" \ . diff --git a/docker/fetch_llama_prebuilt.py b/docker/fetch_llama_prebuilt.py index 503723c9cc..3eb50d67a6 100644 --- a/docker/fetch_llama_prebuilt.py +++ b/docker/fetch_llama_prebuilt.py @@ -19,8 +19,13 @@ tensor mappings match the binaries -- the layout unsloth_zoo's check_llama_cpp() expects: binaries, converter and gguf-py/ at the install dir root. +The tag may be the literal "latest" (or empty), in which case the newest +published release of RELEASE_REPO is resolved at build time by following the +/releases/latest redirect (no API token, no API rate limit).

Add a baked helper so a running container can update in place: docker exec unsloth-studio-update It updates only the Studio packages -- the backend code and the pre-built frontend, which ships inside the unsloth wheel -- with `pip install -U --no-deps unsloth unsloth_zoo`, then restarts just the studio service via supervisor. The torch/CUDA stack is left untouched, so it is safe in both GPU and CPU-only containers. This deliberately avoids `unsloth studio update`, which re-runs the full installer and re-probes the GPU to pick torch wheels -- in a container started without --gpus that finds no GPU and can downgrade torch to CPU/cu126. Options: --ref installs from git (track main) instead of the latest PyPI release; --with-deps also updates dependencies; --no-restart defers the restart. After the swap the helper smoke-imports studio.backend.main and, if a transitive dep is now missing, points the user at --with-deps.

The -r value was passed to the real pip unchanged, so torch / transformers / vLLM / nvidia pins inside the file could overwrite the baked cu128 stack or push transformers into the base venv. _filter_requirements_file() applies the same _KEEP / transformers-sidecar rules per line, writes the survivors to a temp file, keeps comments, option lines, nested includes and urls verbatim, and records a pinned transformers version for the sidecar. - install.sh + Dockerfile.studio + docker-publish.yml: forward the resolved unsloth-zoo ref into the Studio build. install.sh --local overlaid unsloth-zoo from git main regardless of the operator-requested or base-image ref, so the full image could run a different zoo than the base. install.sh now honors UNSLOTH_ZOO_REF across all four --local overlays, Dockerfile.studio passes UNSLOTH_STUDIO_ZOO_REF through to it, and the workflow resolves one zoo ref in the prepare job and shares it with both the base and Studio builds. - Dockerfile + docker-publish.yml: pin unslothai/notebooks to one resolved commit. Each arch leg cloned HEAD independently, so the same tag could seed different baked templates and .unsloth_template_commit depending on the pulled platform. The prepare job freezes notebooks to one sha (like the llama.cpp prebuilt tag) and the Dockerfile fetches that single ref at depth 1. --- .github/workflows/docker-publish.yml | 95 ++++++++++++++++++++-------- docker/Dockerfile | 14 +++- docker/Dockerfile.studio | 6 ++ docker/unsloth_pip_shim.py | 69 ++++++++++++++++++-- install.sh | 34 ++++++---- 5 files changed, 173 insertions(+), 45 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index d68f7c1889..e86fec2790 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -48,6 +48,10 @@ on: description: 'unslothai/llama.cpp prebuilt release tag to bake (blank = newest)' required: false default: '' + notebooks_ref: + description: 'unslothai/notebooks git ref to bake (resolved to one commit)' + required: false + default: 'main' env: REGISTRY: docker.io @@ -85,6 +89,12 @@ jobs: contents: read outputs: llama_tag: ${{ steps.llama.outputs.tag }} + # One zoo ref + one notebooks commit, resolved here so BOTH arch legs of + # the base build (and the Studio build) bake the identical bits.

JupyterLab labextension (prebuilt in a throwaway builder stage, so the runtime image stays Node-free): - Unsloth Dark (Monokai) theme, adaptive light/dark by system preference - Colab-style ArrowDown/Up cell navigation - top-bar Unsloth logo (stock Jupyter logo disabled and locked) - #@title lines render as collapsible Heading-2 form bars - Ctrl+A in a cell output selects only that output, not the whole notebook (the old behaviour ran notebook:select-all and was laggy) - right activity bar hidden by default - overrides.json: per-cell run button without auto-advance, labeled Restart and Run All, windowing off so collapsing an output does not snap to the cell top, news/update prompts suppressed Studio and login branding: Unsloth favicon, page logo, and a dark Unsloth login page that rotates through the curated Studio sloth stickers (fail-soft to the logo). Notebook organization and Colab compatibility (base image): - categorized folder view built from relative symlinks mirroring the README sections, rebuilt each boot; real .ipynb files never moved, and the symlink tree is invisible to the sync state machine - AMD-* notebooks shown only on an AMD/HIP host (autodetected) - Docker-only strip of the Colab "Run all on Colab" intro sentence from unedited notebooks (upstream notebooks unchanged) - hoist %%capture above a leading #@title form so the cell runs - the per-cell transformers-sidecar log is silent unless UNSLOTH_ENABLE_LOGGING=1 Dependency pinning and naming: the curated notebook extras are pinned to their resolved versions for reproducible rebuilds; decord is split into its own fail-soft install (no aarch64 wheel). The lean base image is renamed from :base to :core. Adds tests/validate_studio_features.py, a static self-test for the labextension plugins, overrides keys, and branding wiring. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: address review feedback on the JupyterLab/Studio UX - unsloth_nb_view.py: rebuilding the categorized view no longer deletes user files. The view is also JupyterLab's landing dir, so a user may save real notebooks there; _clear_view now unlinks only the symlinks we own and removes only folders that end up empty, leaving regular files in place. It also tests islink before isdir, so a view that is itself a symlink to a directory is unlinked instead of being walked into (which would have wiped the symlink target). - studio_launch.sh: derive the landing URL and preferred_dir from UNSLOTH_NOTEBOOKS_VIEW_DIR / UNSLOTH_SKIP_NOTEBOOK_VIEW, the same env the sync script uses, instead of hard-coding /workspace/Unsloth Notebooks. A relocated or disabled view no longer opens JupyterLab on a missing folder; it falls back to the default /lab over /workspace. - Dockerfile.studio: the labext-builder stage now installs Node 20 from NodeSource. Ubuntu 24.04's distro nodejs is 18, below JupyterLab 4.6's declared Node >=20 engine. Node stays confined to the throwaway builder stage, so the runtime image is unchanged. - .dockerignore: explicitly allowlist jupyter/install_sloth_stickers.py alongside its sibling jupyter assets, rather than relying on the directory re-inclusion. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: publish lean image as :core and full image as :studio Complete the base->core (and "studio as studio") tag rename so the publish workflow matches the user-facing helpers and the Dockerfile.studio header. - The lean training image now publishes as :core (core-, core-nightly, core-sha-*); run.sh / docker_confirm.* already told users to pull :core, but docker-publish.yml still tagged it :base, so that pull would have 404'd. The per-arch digest artifacts are renamed to match. - The full Studio image keeps :latest and gains a stable :studio alias, matching the Dockerfile.studio header. Both the merge and post-publish smoke-test metadata blocks are updated together. Internal "base image" wording (the layer Studio builds FROM) is left as-is. * docker: address second-round review feedback on the JupyterLab/Studio UX - studio_launch.sh: also gate the categorized-view landing URL on UNSLOTH_SKIP_NOTEBOOK_SYNC (the entrypoint skips building the view entirely in that mode), not just UNSLOTH_SKIP_NOTEBOOK_VIEW, so a no-sync container does not land on a missing folder. - Dockerfile.studio: scope the sticker-install "|| echo" fallback to only the sticker step via a { ...; } group. It was attached to the whole branding && chain, so a failure in a REQUIRED step (JS resolve, favicon/logo/login copy) was swallowed and the build continued with broken branding. - unsloth_nb_view.py: when creating the categorized symlinks, only replace our own stale symlinks; if a real user file already occupies that name, keep it and skip the link instead of os.remove-ing it. - overrides.json: drop doNotDisturbMode (it silenced ALL JupyterLab toasts, including kernel-restart / connection-drop feedback). The news/update prompts are already off via fetchNews / checkForUpdates. - Dockerfile: keep decord mandatory on amd64 (fail the build on a missing or incompatible wheel) and only fail-soft on arm64/other arches that have no wheel. - cellNav.ts: do not hijack ArrowUp/Down when focus is in an interactive output widget / form control, or while a completion popup is open, so ipywidgets controls and autocomplete at cell boundaries keep working. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: keep Studio branding RUN free of comments inside the line continuation Move the sloth-sticker fail-soft explanation above the RUN so no comment line sits between backslash-continued commands. BuildKit strips such comments, but keeping the RUN body a plain && chain removes the ambiguity for non-BuildKit builders and static linters. The { ...; } fail-soft scoping is unchanged. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: AGPLv3 attribution + integrity guard for the Studio/JupyterLab image Make it obvious the image is built by Unsloth and hard to white-label out with a shallow find-and-replace, and surface the AGPLv3 license + copyright in the UI. Visible attribution (labextension): - Help > "About Unsloth Docker Studio" dialog (about.ts): Unsloth logo, the AGPLv3 notice, "Copyright 2026-Present the Unsloth team", and source/website/ license links. Added to the Help menu and the command palette. - The JupyterLab loading splash is replaced with a spinning Unsloth logo (splash.ts, provides ISplashScreen; honors prefers-reduced-motion). The stock @jupyterlab/apputils-extension:splash is disabled+locked at build time, like the stock logo. - AGPLv3 footer (license + copyright + links) on the branded login page. - Labextension relicensed AGPL-3.0-only; SPDX headers on every source file. Anti-tamper (no encoded/obfuscated strings -- plain readable text only; the one data URI is the logo image): - A canonical, plain-text attribution set lives in unsloth_branding.py with a TypeScript mirror (branding.ts) bundled verbatim into the labextension, so the phrase, copyright, links and plugin ids are spread across independent layers. - unsloth_branding.py verifies all of these across the installed files (AGPLv3 text, login footer, theme, labextension package + built bundle strings, logo, favicon) and fails loudly if any are missing. It runs at three layers: build time (fails the image build), the whole-container launcher (studio_launch.sh refuses to start), and as a jupyter_server extension (refuses to serve JupyterLab). - tests/studio/test_branding_guard.py: positive + per-marker negative coverage, plus a check that no base64/decoder obfuscation crept into the attribution. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: address #6681 review round 2 (colab magics, output select, branding guard) - unsloth_colab_compat.py: only hoist a leading `%%` cell magic above the Colab `#@title` form for magics whose body runs as code (capture/time/bash/python/ ...). Content magics (%%writefile, %%html, %%latex, ...) are left untouched so the form comment is never injected into the written file / rendered output. - outputSelect.ts: stop trusting the text selection anchor to decide ownership of Ctrl/Cmd+A. A stale selection inside an output survives a click onto a command-mode cell or the file browser, which made select-all keep re-selecting the old output. Gate on the keystroke target or the last pointer-down (reset to null on any click outside an output) instead. - unsloth_branding.py: also reject page_config.json that disables the Unsloth labextension or any of its plugin ids via disabledExtensions (dict or list form); that leaves the bundle on disk so the prior checks passed while the logo/About/splash attribution was stripped at load. Lock unsloth-jupyterlab in Dockerfile.studio as well (defense in depth), and add guard tests. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * labext: pin JupyterLab extension deps; confirm.ps1 /login probe Pin the unsloth-jupyterlab npm deps to exact versions matching the baked jupyterlab==4.6.0 (builder stays 4.5.9, its newest release) instead of floating ^/~ ranges, so the same commit always builds the same labextension bundle. Also probe JupyterLab /login (not /api, which 403s behind a password hash) in the Windows confirmation script. * docker: categorize AMD/domain notebooks and wire the feature validation into CI unsloth_nb_view.parse_readme only reset the folder section on level-3 (###) headings. The notebooks README carries level-1 domain headers (# AMD Notebooks, # Kaggle Notebooks) with their own nb/*.ipynb link tables and no intervening ###, so those notebooks were mis-filed under the previous stale section (all 148 AMD notebooks landed in Other Notebooks on an --amd build). Reset on any heading level and strip a leading emoji/symbol run so the domain notebooks get their own clean folder. Also run tests/validate_studio_features.py explicitly in the repo CPU job. It is named validate_* (not test_*) so pytest never collected it, which meant a regression in the notebook view, Colab compat, strip, JupyterLab defaults or login branding failed CI only when run by hand. * labext: use caret ranges so jlpm dedups JupyterLab/Lumino singletons The exact pins introduced earlier (@jupyterlab/* 4.6.0, @lumino/widgets 2.8.0, @jupyterlab/builder 4.5.9) break the Dockerfile.studio labext-builder stage. Exact-pinning the framework packages defeats jlpm's (yarn classic) hoisting: transitive @jupyterlab deps request caret ranges that resolve to newer patch releases (e.g. @jupyterlab/ notebook pulls @jupyterlab/cells ^4.6.0 -> a newer patch), so jlpm installs a second nested copy alongside the exact top-level one. Two copies of @jupyterlab/cells and @lumino/widgets in the tree produce TS2345 "not assignable" errors (protected-member/identity mismatch) and the build fails. Caret ranges let jlpm collapse every @jupyterlab and @lumino package to a single hoisted copy, which is required for a JupyterLab prebuilt (federated) extension: at runtime those packages are shared singletons provided by the host JupyterLab, so the build-time versions only need to type-check against one consistent tree, not match an exact runtime patch. This is the version set the published image was built and validated with end to end. Verified by building the labext in isolation against the base image (Node 20 + bundled jlpm): caret ranges build clean (webpack compiled successfully); the exact pins fail with the duplicate-package TS errors. * ci(studio-backend): trigger on docker/** so the JupyterLab feature validation guards docker-only changes The 'Docker JupyterLab/notebook feature validation' step runs tests/validate_studio_features.py, which checks docker/jupyter (the labextension, overrides.json, login branding) and the docker notebook helpers. The pull_request paths filter listed studio/unsloth/tests but not docker/**, so a PR that only touches docker/ would skip that step and a regression in those files could pass CI. Add docker/** so the validation runs whenever the files it checks change. * jupyter: center the login card and place the attribution below it #site was a flex container using the default row direction with two children (the login card and the AGPLv3 attribution), so they rendered side by side: the card sat left of centre and the attribution floated up to the top-right. Stack them in a column so the card is horizontally centred and the attribution sits below it as a footer, matching the intended single-column layout. * jupyter: refresh Studio attribution, About dialog and loading splash - Attribution now reads 'Built by the Unsloth team' with a single Apache 2.0 / AGPLv3 license link (to the repo license section) on the login page and in the About dialog, replacing the plain 'Built by Unsloth. Licensed under the GNU AGPLv3.' line. The integrity guard, its canonical PHRASE and the branding tests are updated to match. - About dialog: left-align the link rows so the labels line up instead of each row centering independently; add an 'Unsloth Reference' link to the docs, and a Licenses section listing Unsloth Studio (AGPLv3) and Unsloth Core (Apache 2.0) alongside the full license link. - Loading splash now reads 'Loading Unsloth Docker' instead of the attribution label, via a dedicated SPLASH_LABEL constant. * docker: document the branding attribution as an AGPLv3 Section 7 notice Add docker/NOTICE and docker/jupyter/BRANDING.md so the Unsloth attribution that unsloth_branding.py enforces is also a written license condition, not only a build check. docker/NOTICE designates the attribution (the "Built by the Unsloth team" label, the copyright line, the license notice, the logo and theme, and the Help > About links) as required Appropriate Legal Notices under AGPLv3 Section 7(b), referencing /studio/LICENSE.AGPL-3.0 and /LICENSE. BRANDING.md is a human-readable note next to the guard describing what must stay, where it lives and how it is enforced. * ci(studio-backend): restore docker/** trigger path The docker/** pull_request path added in b558bc7d was dropped by a later rebase, so the "Docker JupyterLab/notebook feature validation" step (which runs tests/validate_studio_features.py against docker/jupyter branding and notebook helpers) no longer ran on PRs that only touch docker/. Re-add docker/** so a docker-only change is validated on the PR rather than only after merge to main. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- .github/workflows/docker-publish.yml | 35 +- .github/workflows/studio-backend-ci.yml | 11 + docker/.dockerignore | 20 ++ docker/Dockerfile | 9 +- docker/Dockerfile.studio | 90 +++++- docker/NOTICE | 41 +++ docker/docker_confirm.ps1 | 2 +- docker/docker_confirm.sh | 4 +- docker/jupyter/BRANDING.md | 50 +++ docker/jupyter/favicon.ico | Bin 0 -> 16901 bytes docker/jupyter/install_sloth_stickers.py | 78 +++++ .../unsloth_branding_guard.json | 7 + docker/jupyter/login.html | 118 +++++++ docker/jupyter/logo.png | Bin 0 -> 14416 bytes docker/jupyter/overrides.json | 40 +++ docker/jupyter/unsloth_branding.py | 305 ++++++++++++++++++ docker/jupyter/unsloth_labext/.gitignore | 7 + docker/jupyter/unsloth_labext/.yarnrc.yml | 1 + docker/jupyter/unsloth_labext/package.json | 54 ++++ docker/jupyter/unsloth_labext/src/about.ts | 98 ++++++ docker/jupyter/unsloth_labext/src/branding.ts | 30 ++ docker/jupyter/unsloth_labext/src/cellNav.ts | 126 ++++++++ .../jupyter/unsloth_labext/src/colabTitle.ts | 161 +++++++++ docker/jupyter/unsloth_labext/src/index.ts | 81 +++++ docker/jupyter/unsloth_labext/src/logo.ts | 8 + .../unsloth_labext/src/outputSelect.ts | 136 ++++++++ docker/jupyter/unsloth_labext/src/splash.ts | 89 +++++ docker/jupyter/unsloth_labext/src/uiChrome.ts | 60 ++++ docker/jupyter/unsloth_labext/style/index.css | 6 + .../unsloth_labext/style/variables.css | 97 ++++++ docker/jupyter/unsloth_labext/tsconfig.json | 26 ++ docker/run.sh | 4 +- docker/studio_launch.sh | 38 +++ docker/unsloth_colab_compat.py | 101 ++++++ docker/unsloth_ipython_startup.py | 10 + docker/unsloth_nb_compat.py | 16 +- docker/unsloth_nb_strip_colab.py | 216 +++++++++++++ docker/unsloth_nb_view.py | 245 ++++++++++++++ docker/unsloth_sync_notebooks.sh | 74 +++++ tests/studio/test_branding_guard.py | 252 +++++++++++++++ tests/validate_studio_features.py | 279 ++++++++++++++++ 41 files changed, 2997 insertions(+), 28 deletions(-) create mode 100644 docker/NOTICE create mode 100644 docker/jupyter/BRANDING.md create mode 100644 docker/jupyter/favicon.ico create mode 100644 docker/jupyter/install_sloth_stickers.py create mode 100644 docker/jupyter/jupyter_server_config.d/unsloth_branding_guard.json create mode 100644 docker/jupyter/login.html create mode 100644 docker/jupyter/logo.png create mode 100644 docker/jupyter/overrides.json create mode 100644 docker/jupyter/unsloth_branding.py create mode 100644 docker/jupyter/unsloth_labext/.gitignore create mode 100644 docker/jupyter/unsloth_labext/.yarnrc.yml create mode 100644 docker/jupyter/unsloth_labext/package.json create mode 100644 docker/jupyter/unsloth_labext/src/about.ts create mode 100644 docker/jupyter/unsloth_labext/src/branding.ts create mode 100644 docker/jupyter/unsloth_labext/src/cellNav.ts create mode 100644 docker/jupyter/unsloth_labext/src/colabTitle.ts create mode 100644 docker/jupyter/unsloth_labext/src/index.ts create mode 100644 docker/jupyter/unsloth_labext/src/logo.ts create mode 100644 docker/jupyter/unsloth_labext/src/outputSelect.ts create mode 100644 docker/jupyter/unsloth_labext/src/splash.ts create mode 100644 docker/jupyter/unsloth_labext/src/uiChrome.ts create mode 100644 docker/jupyter/unsloth_labext/style/index.css create mode 100644 docker/jupyter/unsloth_labext/style/variables.css create mode 100644 docker/jupyter/unsloth_labext/tsconfig.json create mode 100644 docker/unsloth_colab_compat.py create mode 100644 docker/unsloth_nb_strip_colab.py create mode 100644 docker/unsloth_nb_view.py create mode 100644 tests/studio/test_branding_guard.py create mode 100644 tests/validate_studio_features.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 18a8d4de0a..6682e09113 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -274,7 +274,7 @@ jobs: - name: Upload digest uses: actions/upload-artifact@v4 with: - name: digests-base-${{ matrix.platform == 'linux/amd64' && 'amd64' || 'arm64' }} + name: digests-core-${{ matrix.platform == 'linux/amd64' && 'amd64' || 'arm64' }} path: /tmp/digests/* if-no-files-found: error retention-days: 1 @@ -301,7 +301,7 @@ jobs: - uses: actions/download-artifact@v4 with: path: /tmp/digests - pattern: digests-base-* + pattern: digests-core-* merge-multiple: true - uses: docker/setup-buildx-action@v3 @@ -322,17 +322,17 @@ jobs: # and collide with the Studio image that legitimately owns :latest. flavor: latest=false tags: | - # The lean training image publishes under the base- prefix;

The old extra pulls xformers 0.0.34, which hard-pins torch==2.10.0 and conflicts with the torch==2.11.0 held throughout the build; the torch2110 family pulls xformers 0.0.35 (no torch pin) and resolves cleanly. This needs an unsloth carrying the torch2110 CUDA extras on main, so merge the torch2110 extras PR first (default UNSLOTH_REF=main). - notebook-deps assertion: startswith('2.10.0') -> '2.11.0' so the layer actually verifies the torch it now installs. - refresh the torch2100/xformers 0.0.34 references in the surrounding comments to the torch2110/0.0.35 line. sm_103 (B300/GB300) JIT override (Codex item): The cu13 NVRTC/ptxas override was arm64-only (sm_121), and its comment claimed triton 3.6.0 bundles cu13 ptxas and set TRITON_PTXAS_PATH -- neither was true: triton 3.6.0's bundled ptxas is CUDA 12.8 (V12.8.93, tops out at sm_120) and TRITON_PTXAS_PATH was never set. So sm_103 (amd64) and even sm_121 (arm64) Triton JIT were unfixed. Run the cu13 install on both arches and actually wire the ptxas override: - NVRTC swap (cu13 libnvrtc.so.13 over torch's bundled cu12.8 .so.12) now runs on amd64 too. - ENV TRITON_PTXAS_PATH=/usr/local/cuda-13.0/bin/ptxas routes every Triton JIT through the cu13 ptxas. Global rather than per-arch is safe: cu13.0 ptxas spans sm_70..sm_121 (verified: Volta/Turing/Ampere/Hopper through Blackwell), so no regression for the older GPUs in the arch list. Verified on amd64 in the built base image: cuda-nvrtc-13-0/cuda-nvcc-13-0 install cleanly from the base's CUDA repo, ptxas lands at /usr/local/cuda-13.0/bin/ptxas (V13.0.88) and libnvrtc.so.13 at /usr/local/cuda-13.0/lib64/. The sm_103/sm_121 runtime path itself is not hardware-tested (no such GPU on hand); precompiled SASS still covers both via sm_100/sm_120 forward-compat, so only JIT-heavy paths rely on this. --- docker/Dockerfile | 93 +++++++++++++++++++++++++---------------------- 1 file changed, 50 insertions(+), 43 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 9c3c7306fa..96b83aafc8 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -17,10 +17,10 @@ # * Unsloth's runtime kernels are Triton, which JIT-compiles per device at # first run.

That is only safe when both venvs run the same torch, but the pre-dedup guard only checked the CUDA family (endswith('+cu128')). A Studio venv that installed torch 2.10.0+cu128 (an installer capped below the base's 2.11.0, or a build-time nvidia-smi fallback) would pass that check yet mismatch the base's 2.11.0+cu128, and the dedup would link incompatible libs. Capture the base venv's torch from its metadata and assert the Studio venv torch equals it exactly (version and family) before the dedup runs, so a mismatch fails the build loudly instead of silently linking skewed CUDA libs. Comparing to the base venv also avoids hardcoding the version here. The Studio venv reaches torch 2.11.0+cu128 via the installer's UNSLOTH_TORCH_INDEX_FAMILY=cu128 handling and its CUDA torch spec allowing 2.11.x. --- docker/Dockerfile.studio | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/docker/Dockerfile.studio b/docker/Dockerfile.studio index d6480704f3..2f51481830 100644 --- a/docker/Dockerfile.studio +++ b/docker/Dockerfile.studio @@ -136,12 +136,18 @@ RUN set -eux \ UNSLOTH_ZOO_REF="${UNSLOTH_STUDIO_ZOO_REF}" \ UNSLOTH_PYTHON=3.12 \ bash install.sh --local \ - # Fail loud if the Studio venv torch missed the pinned CUDA family (an - # install.sh that ignores UNSLOTH_TORCH_INDEX_FAMILY falls back to - # nvidia-smi probing, which cannot work at build time and lands on cu126 - # wheels with no sm_100/sm_120 kernels). metadata check only: importing - # torch needs native libs, which QEMU arm64 builds cannot load. - && "${UNSLOTH_STUDIO_HOME}/unsloth_studio/bin/python" -c "import sys; from importlib.metadata import version; assert sys.version_info[:2] == (3, 12), 'Studio venv python %d.%d is not 3.12 (UNSLOTH_PYTHON pin ignored) -- CUDA dedup below depends on it' % sys.version_info[:2]; v = version('torch'); assert v.endswith('+${TORCH_FAMILY}'), 'Studio venv torch ' + v + ' does not match ${TORCH_FAMILY}'; print('Studio venv python %d.%d' % sys.version_info[:2], 'torch', v)" \ + # Fail loud unless the Studio venv torch EXACTLY matches the base venv + # torch (version AND CUDA family) before the dedup below symlinks the two + # venvs' CUDA libs together.

UNSLOTH_REF / UNSLOTH_STUDIO_REF were raw expressions re-evaluated per base arch leg and in the Studio build, so a mutable branch (the workflow_dispatch default unsloth_ref=main) advancing during the run could bake different unsloth commits under one manifest. Resolve once (same precedence: dispatch input, else pushed tag, else triggering sha, else main; ls-remote a branch/tag to a sha, mirroring the zoo/notebooks steps) and read needs.prepare.outputs.unsloth_ref everywhere. Dockerfile.studio: run the Studio venv NVRTC cu13 swap on both arches, not arm64 only. amd64 sm_103 (B300/GB300) needs cu13 NVRTC just as arm64 sm_121 does, and the CUDA dedup never touches cuda_nvrtc, so an amd64 Studio venv would otherwise keep its bundled cu12.8 libnvrtc and fail NVRTC/jiterator JIT on compute_103. The base cu13 layer installs cuda-nvrtc-13-0 on both arches, so the target .so.13 exists here regardless of TARGETARCH. unsloth_pip_shim.py: close three ways a protected package slipped past _KEEP. Treat -e/--editable as a value-taking flag paired with its target and drop both when the target is protected (was leaving a dangling -e that failed the cell); filter -P/--upgrade-package values through _KEEP (a named baked package could be refreshed while installing another target); and parse the PEP 427 distribution name out of a wheel URL/path so a bare `pip install https://.../torch-...whl` drops instead of reinstalling the baked torch. Non-protected editables, upgrade selectors, and wheels are unchanged.

An editable line (-e/--editable ) inside a -r requirements file is a real install target, so a protected editable there is now classified and dropped like the command-line case (new _parse_editable). pip/uv accept the attached short forms -rreqs.txt / -cconstraints.txt / -epath / -Pname as one token; these were falling through as opaque options (so an attached -r-only cell no-op'd and an attached -c/-e/-P value bypassed _KEEP), so the 2-char flag is now split from its value and routed through the separated-form handling. And a nested -c constraint inside a -r file no longer records its transformers pin as an install request (a constraint is not a request; mirrors the top-level -c path). entrypoint.sh / Dockerfile: gate the CUDA 13 ptxas + NVRTC to sm_103 / sm_121 at runtime instead of a global build-time default. A cu13 cubin needs a >= 580 driver to LOAD even when it targets an older arch (CUDA has forward, not backward, cross-major driver compatibility), but the image supports Turing.. sm_120 on a 570+ driver, so the previous global TRITON_PTXAS_PATH ENV + cu13 NVRTC symlink would break ordinary Triton/NVRTC JIT on 570-579 driver hosts. The build still bakes cu13 (saving the cu12.8 NVRTC as .cu128.orig); a new select_cuda_jit_tools() in the entrypoint reads the device compute_cap and only activates cu13 for sm_103/sm_121 (which ship >= 580 drivers), otherwise leaving Triton on its bundled cu12.8 ptxas and restoring the cu12.8 NVRTC in both the base and Studio venvs. The base ENTRYPOINT runs for the Studio image too.

Copy to a temp sibling and publish with one atomic rename; dst.exists() is now a truthful complete-tree signal. 2. unsloth_run.py --out truncated the existing output before nbconvert ran, so a timeout, missing kernel, or failed cell irreversibly destroyed the previous result. The input copy and executed result are staged as temp files next to the destination and published with os.replace only on exit code 0. 3. unsloth_nb_view.py cleanup treated every symlink in the view as its own: user-created links (and an operator's view-root routing symlink) were deleted on every rebuild. Cleanup now removes only links that resolve into the notebooks tree it links from, and builds inside a view-root symlink's target instead of unlinking it. 4. unsloth_llama_update.sh: the unconditional EXIT trap deleted the .old backup even when it was the only remaining copy (signal between the two renames, or a failed swap whose restore also failed). The handler now restores the backup first when the install dir is missing and removes it only after the new tree is verifiably active; HUP/INT/TERM route through the same handler. 5. unsloth_pip_shim.py: transitive dependencies could replace the baked torch stack (reproduced with a wheel requiring torch==99.0). Every forwarded install now carries a constraints file pinning the installed protected set, turning the swap into ResolutionImpossible. 6. unsloth_pip_shim.py: ${UPPER} env references in requirements files were classified before pip expanded them, bypassing the protected-package filter; the shim now expands with pip's exact regex first. 7. unsloth_pip_shim.py: a failure writing the filtered requirements copy returned the ORIGINAL file, forwarding exactly the protected pins it had detected; it now fails closed. 8. docker-publish.yml: workflow_dispatch defaulted unsloth_ref to 'main' while the stable-tag gates require '', so UI-default manual runs could never advance :core/:latest/:studio; the default is now empty. 9. entrypoint.sh: the sm_103/sm_121 branch rewrote libnvrtc.so.12 to the CUDA-13 build but the ordinary-GPU branch never restored it, so a container moved to an older GPU kept the stale link; it is now reversed when it points exactly at the .cu13 target. Rejected after verification (no code change): timeout=0 semantics are documented at the site with no zero callers, TORCHINDUCTOR_COMPILE_THREADS override is deliberate, fetchNews is a string enum per JupyterLab's schema, :base tag appears in no in-tree doc, install-cell digest exclusion is the module's stated contract, transformers ceiling semantics are documented, and the cloudflared download mirrors the pre-existing Studio downloader (Cloudflare publishes no checksum asset). The UNSLOTH_ALLOW_CPU import crash lives in unsloth_zoo (compiler.py / loss_utils.py capability probes), not in this diff; the image consumes the zoo fix automatically once merged there. Tests: shim suite extended to 63 (constraints, env expansion, fail-closed), jit-selector suite to 14 (NVRTC reversal transitions), plus staged-publish and ownership repros; wider studio install suite green except failures reproduced at the unmodified head. --- .github/workflows/docker-publish.yml | 21 +++-- docker/entrypoint.sh | 25 ++++-- docker/unsloth_llama_update.sh | 29 ++++++- docker/unsloth_nb_view.py | 61 ++++++++----- docker/unsloth_pip_shim.py | 76 ++++++++++++++-- docker/unsloth_run.py | 49 ++++++++--- studio/install_llama_prebuilt.py | 21 ++++- tests/python/test_unsloth_pip_shim.py | 116 ++++++++++++++++++++++++- tests/sh/test_select_cuda_jit_tools.sh | 14 ++- 9 files changed, 349 insertions(+), 63 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index e2cce67c52..9371d8e0d2 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -37,9 +37,14 @@ on: workflow_dispatch: inputs: unsloth_ref: - description: 'unsloth git ref to bake in' + # Blank means "the dispatched branch" (the resolver below falls back to + # the triggering sha, then main).

Names match exactly after normalization, so a user dir named my-torch-utils is untouched, and a metadata-less directory still passes through. 2. unsloth_nb_pip_magic.py only rewrote literal `!python -m pip`, so the `!{sys.executable} -m pip ...` form notebooks use to target the running kernel (and absolute interpreter paths) bypassed the PATH shim entirely. Input transformers see the raw cell text before IPython expands the braces, so the matcher now also covers {sys.executable} (quoted or bare) and quoted/bare interpreter paths ending in python[0-9.]*(.exe) before -m pip|uv. 3. unsloth_pip_shim.py did not strip uv's --exact, which performs an exact sync that removes every installed package outside the kept target's closure (vLLM, bitsandbytes, the NVIDIA libs); `uv pip install --exact peft` would strip the baked stack after the filter kept it. --exact now joins the resolver-wide destructive flags dropped in shim mode. 4. entrypoint.sh: the arm64 image bakes a CUDA 13 llama.cpp because upstream (unslothai/llama.cpp) publishes no CUDA 12 arm64 asset, while the torch stack (cu128) runs on a 570-series driver. A CUDA 13 cubin cannot load on a 570-579 driver, so on GH200/GB200 hosts below 580 GGUF export and Studio chat fail while training works. The entrypoint now warns up front on aarch64 + driver < 580 instead of letting llama-server fail later.

Comments that pointed at the removed dev scripts now name the underlying command or artifact instead. Non-comment lines of both Dockerfiles and the workflow are byte-identical. unsloth_sync_notebooks.sh folds the three copies of the override -> PATH -> sibling helper resolution into one resolve_helper(), behavior verified for all four modes including graceful absence under set -u. unsloth_pip_shim.py collapses an if/else whose branches were identical and merges the structurally duplicate _parse_include/_parse_editable into one _parse_flag_line. The test suite folds 35 near-duplicate tests into 8 parametrized groups with exact case-count parity (69 collected before and after, 81 passing including the nb-pip-magic suite). Cuts another 144 lines with zero behavior change outside the two refactors. --- .github/workflows/docker-publish.yml | 80 ++----- docker/Dockerfile | 95 +++----- docker/Dockerfile.studio | 15 +- docker/unsloth_pip_shim.py | 61 ++--- docker/unsloth_sync_notebooks.sh | 71 ++---- tests/python/test_unsloth_pip_shim.py | 328 +++++++++++--------------- 6 files changed, 253 insertions(+), 397 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index f568689c1e..6288d59a7d 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -80,12 +80,15 @@ permissions: jobs: # --------------------------------------------------------------------------- - # Resolve the llama.cpp prebuilt release ONCE, up front, so both arch legs of - # the base build bake the identical GGUF binaries.

The pip shim's _VALUE_FLAGS now covers every value-taking flag of uv pip install and pip install (generated from both tools' --help). The separated form `uv pip install --torch-backend cu128 torch` used to drop the protected torch but exec uv with no install target at all (uv hard-errors) instead of no-oping like the attached `=` form, and `--extra torch peft` misread the extra name as a protected target, leaving a dangling --extra that swallowed peft. Adds parametrized regressions plus help-derived drift guards so a future uv/pip value flag cannot silently reintroduce the misparse. unsloth-llama-update now detects when the install dir is itself a mount point (the documented -v unsloth_llama:/opt/unsloth/llama.cpp persistence recipe, where rename(2) fails EBUSY) and swaps the bundle CONTENTS inside the mounted tree, so the update lands in the volume and stays persistent. Work and backup dirs live under the mount (same-fs renames), the abort trap restores the old contents even mid-swap, and the non-mounted path keeps the whole-dir rename. Verified: in-place swap preserves the dir inode and ownership marker, failed fetch leaves the install untouched, simulated mid-swap abort restores fully. --- docker/entrypoint.sh | 12 ++++ docker/unsloth_llama_update.sh | 91 ++++++++++++++++++++++----- docker/unsloth_pip_shim.py | 54 ++++++++++++++++ tests/python/test_unsloth_pip_shim.py | 80 +++++++++++++++++++++++ 4 files changed, 222 insertions(+), 15 deletions(-) diff --git a/docker/entrypoint.sh b/docker/entrypoint.sh index 36138dcfd3..085dbe2b65 100755 --- a/docker/entrypoint.sh +++ b/docker/entrypoint.sh @@ -229,6 +229,18 @@ if major < 7 or (major == 7 and minor < 5): if major < 8: print(f"NOTE: {name} is Turing (sm_{major}{minor}) -- bfloat16 is not supported.") print(" Unsloth will fall back to fp16.

Both arches now take the plain huggingface extra and amd64 pins xformers==0.0.35 explicitly in the same resolve (it requires torch>=2.10 without an exact pin, pairing with the baked 2.11.0; verified on PyPI, x86_64 wheels only, matching the arm64 exclusion). This decouples the base image from the pending extras PR. The Studio build now receives the SAME llama.cpp tag the base image baked: Dockerfile.studio grows a LLAMA_PREBUILT_TAG arg exported as UNSLOTH_LLAMA_TAG to install.sh (setup.sh honours it; the "latest" default is byte-identical to setup.sh's own default for local builds), and the publish workflow forwards the prepare job's resolved tag in the studio build-args. Without the pin a dispatch override or an upstream release landing between the two jobs let the no-GPU Studio build re-resolve "latest" and replace the pinned CUDA bundle. The Studio venv-match assertion also needs installer support for torch 2.11 on the CUDA path; that lands in a separate installer PR and is now declared as a merge-order dependency in the PR description (the publish workflow only runs on main pushes, so nothing builds before both are merged). --- .github/workflows/docker-publish.yml | 10 ++++++---- docker/Dockerfile | 28 +++++++++++++--------------- docker/Dockerfile.studio | 7 +++++++ 3 files changed, 26 insertions(+), 19 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 6288d59a7d..8a661d7807 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -438,14 +438,16 @@ jobs: cache-from: type=gha,scope=studio-${{ matrix.platform }} cache-to: type=gha,scope=studio-${{ matrix.platform }},mode=min outputs: type=image,name=${{ env.REGISTRY }}/${{ env.IMAGE_NAME }},push-by-digest=true,name-canonical=true,push=true - # Both refs are the SAME resolved shas the base build baked (prepare - # job), so the Studio tree + its zoo overlay match the base venv even - # if the branch moved mid-run.

TileLang JIT and torch.utils.cpp_extension resolve nvcc through /usr/local/cuda, so on the 570-driver hosts this image supports they would emit cu13 cubins that need driver 580 and fail at load. Pin the alternative back to 12.8 right after the cu13 install; the cu13 tools stay reachable by absolute path, which is exactly how the entrypoint activates them, and manual mode prevents future apt flips. run.sh accepted the native --gpus device=0,1 form through an unquoted passthrough, but docker requires the comma-carrying value to be quoted (daemon rejects it with 'cannot set both Count and DeviceIDs'; reproduced against a live daemon, and the docker GPU docs call the quoting out explicitly). A native multi-device selector is now wrapped in the same embedded quotes the other comma paths already use; single-device and pre-quoted forms pass through unchanged. All eight selector forms verified through the case block. --- docker/Dockerfile | 8 ++++++++ docker/run.sh | 6 ++++-- 2 files changed, 12 insertions(+), 2 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 5bc6067154..72587c3354 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -589,6 +589,14 @@ RUN set -eux; \ apt-get install -y --no-install-recommends \ cuda-nvrtc-13-0 \ cuda-nvcc-13-0; \ + # cu13's config-common postinst flips the /usr/local/cuda alternative to + # cuda-13.0 (priority 130 beats 12.8's 128).

The shared default marker leaked one run's transformers pin into later or concurrent runs in the same container: a notebook pinned to 4.57.6 left the marker behind and the next unpinned run's kernel activated the stale sidecar. An empty marker reads as no pin, so pre-creating the file is safe. The vLLM startup wait in dataprep/synthetic.py capped every poll at a full second regardless of the remaining budget, so a fractional timeout could overshoot by up to a second. The final wait is now clamped to the remaining time; verified empirically (timeout=1.1 elapses 1.10s). /workspace and the default HF/Triton cache dirs were root-owned, so docker run --user without a bind mount could not sync notebooks or populate caches. They are now world-writable (a+rwX), matching the documented non-root use the /opt prebuilt placement already supports. --- docker/Dockerfile | 5 ++++- docker/unsloth_run.py | 13 +++++++++++-- unsloth/dataprep/synthetic.py | 10 ++++++++-- 3 files changed, 23 insertions(+), 5 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 5f60589c91..9e7bf98892 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -516,7 +516,10 @@ RUN /opt/unsloth-venv/bin/python /tmp/fetch_llama_prebuilt.py \ ENV UNSLOTH_LLAMA_CPP_PATH=/opt/unsloth/llama.cpp WORKDIR /workspace -RUN mkdir -p ${HF_HOME} ${TRITON_CACHE_DIR} +# World-writable so `docker run --user ` (documented non-root use) can +# create notebooks and populate the default caches without a bind mount. +RUN mkdir -p ${HF_HOME} ${TRITON_CACHE_DIR} \ + && chmod -R a+rwX /workspace # --------------------------------------------------------------------------- # Per-notebook transformers version activation -- run unslothai/notebooks diff --git a/docker/unsloth_run.py b/docker/unsloth_run.py index 95d1f39c90..b4591c7151 100644 --- a/docker/unsloth_run.py +++ b/docker/unsloth_run.py @@ -103,10 +103,19 @@ def main(): env = dict(os.environ) env["UNSLOTH_NB_SHIM"] = "1" # enable safe-install for the notebook's cells + # Per-run marker unless the caller pinned one: the shared default would leak + # this run's transformers pin into later or concurrent runs in the same + # container (their kernels would activate a stale sidecar).

The CUDA runtime base image only carries libcudart, and the only libcublas in the image is torch's wheel copy under site-packages/nvidia/cublas/lib, which was not on the loader path. So the CUDA backend failed to load, and llama.cpp said nothing about it: `--list-devices` printed an empty list and every GGUF request ran on the CPU. Measured in the built image on a B200 with gemma-4-E2B-it UD-Q4_K_XL: 1.6 tok/s from llama-cli and 4.2 tok/s from llama-server. With the fix, the same image and model report `CUDA0: NVIDIA B200` and run at 229 tok/s and 193 tok/s. Studio's GGUF chat and the GGUF export path go through the same bundle, so both were affected. The venv loader config already existed for torchcodec, so cublas/lib joins it there rather than on LD_LIBRARY_PATH: ld.so.conf.d is consulted after DT_RUNPATH, which keeps llama.cpp resolving its own $ORIGIN libs first. cu13/lib comes along for the arm64 bundle's layout. A silent 140x slowdown deserves a build-time gate, so the layer after the fetch runs ldd over libggml-cuda.so, installs the cublas major the bundle actually asks for when it is missing, and fails the build on anything still unresolved. The amd64 bundle wants libcublas.so.12 and torch already provides it; the arm64 bundle is CUDA 13, and deriving the major from ldd keeps that leg honest without hardcoding either. libcuda.so.1 is exempt: nvidia-container-toolkit injects the driver stub at `docker run --gpus`, so it is never resolvable at build time. ldd needs no GPU, so the build stays host-independent. tests/python/test_docker_llama_cuda_backend.py pins the loader entry, the guard, the driver-stub exemption and the ordering. --- docker/Dockerfile | 39 +++++++- .../python/test_docker_llama_cuda_backend.py | 89 +++++++++++++++++++ 2 files changed, 127 insertions(+), 1 deletion(-) create mode 100644 tests/python/test_docker_llama_cuda_backend.py diff --git a/docker/Dockerfile b/docker/Dockerfile index 35083878c1..dc29131350 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -432,10 +432,13 @@ RUN set -eux; \ # Register the venv's torch + NVIDIA lib dirs with the loader so torchcodec can # dlopen them. ld.so.conf.d, NOT LD_LIBRARY_PATH: the cache is consulted after # DT_RUNPATH, so llama.cpp keeps resolving its own $ORIGIN libs first. +# cublas/lib and cu13/lib are here for llama.cpp's libggml-cuda.so, which links +# against libcublas but does not ship it (see the guard after the fetch below).

The cost of dropping it is not a no-op. Measured on a LoRA Qwen2-VL under transformers 5.14.1, with the model's forward hooked so the validator still sees the real signature: asking for logits_to_keep=0 (the whole sequence) reached forward as 1 and returned logits of shape (1, 1, 151936); with the value preserved it reached forward as 0 and returned (1, 88, 151936). Deleting the pops outright would be wrong in the other direction. An explicit num_logits_to_keep raises from _validate_model_kwargs on plain, PEFT, text and vision models alike, because v5 renamed it away, and logits_to_keep raises on the 12 of 79 image-text-to-text architectures whose top-level forward does not take it. So each key is now stripped only when _unsloth_generate_accepts_kwarg says this model would reject it, which is the same predicate the validator uses. Under PEFT, self inside the wrapper is the object the validator later runs against, so the check has no false negatives there. Also softened the comment above the branch. Unsloth 2026.7.5 does pre-inject on a LoRA Qwen2-VL under 5.14.1 and generation succeeds, so "pre-injecting makes the strict validator raise on PEFT models" overstates it. Skipping the injection on v5 is still right: it is redundant, and the arch walk can select a key the top-level model rejects. tests/test_generate_kwarg_gate.py gains four cases covering a preserved supported value, a stripped unsupported one, untouched neighbours, and the absence of the unconditional pop. --- tests/test_generate_kwarg_gate.py | 44 +++++++++++++++++++++++++++++++ unsloth/models/vision.py | 18 ++++++++++--- 2 files changed, 58 insertions(+), 4 deletions(-) diff --git a/tests/test_generate_kwarg_gate.py b/tests/test_generate_kwarg_gate.py index 6d1379d3a9..242fcebfbf 100644 --- a/tests/test_generate_kwarg_gate.py +++ b/tests/test_generate_kwarg_gate.py @@ -130,6 +130,50 @@ def test_generate_kwarg_gate(): assert got is expected, f"{name}: got {got}, expected {expected}" +# --- v5 logits-to-keep filtering ------------------------------------------ +# transformers >= 5 injects logits_to_keep=1 in generate() itself, but the +# injection is guarded by `"logits_to_keep" not in model_kwargs`, so it is a +# DEFAULT.

Every unsloth_cli subcommand that touches the studio backend died on import. `unsloth list-checkpoints` on the published image: ModuleNotFoundError: No module named 'structlog' and the same for train / export / chat, since all four import studio.backend.core.*. structlog is a studio backend requirement, not an unsloth[huggingface] one, so nothing in the base install pulled it in. Added it to the base venv, and added a build-time `from studio.backend.core.export import ExportBackend` so a future missing dependency in that closure fails the build instead of the user's first CLI invocation. That guard has to live in the LAST builder verification block: the closure also needs starlette, which only arrives with vLLM two stages later. 2. flashinfer-jit-cache was pinned to a literal 0.6.6 while vLLM 0.26.0 resolves flashinfer-python 0.6.14. flashinfer raises at import when the two disagree, and that exception is thrown inside the vLLM EngineCore, so Unsloth's GRPO fast_inference path fails at engine start with no earlier warning. A literal pin drifts again on the next vLLM bump, so the version is now read back from the resolved flashinfer-python, and the build proves `import flashinfer` works. Verified on the rebuilt image: flashinfer-python 0.6.14 with flashinfer-jit-cache 0.6.14+cu128, structlog 26.1.0, the export backend importable, and `unsloth list-checkpoints` exiting 0. tests/python/test_docker_llama_cuda_backend.py gains two static cases pinning both: the jit-cache version must be derived rather than literal and the build must import flashinfer, and the base venv must ask for structlog with the CLI reachability guard present. --- docker/Dockerfile | 29 +++++++++++++++++-- .../python/test_docker_llama_cuda_backend.py | 28 ++++++++++++++++++ 2 files changed, 54 insertions(+), 3 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index dc29131350..9348c89d1a 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -121,7 +121,11 @@ RUN set -eux \ "bitsandbytes>=0.49.2,!=0.46.0,!=0.48.0" \ "unsloth_zoo @ git+https://github.com/unslothai/unsloth-zoo@${UNSLOTH_ZOO_REF}" \ "unsloth[${UNSLOTH_EXTRA}] @ git+https://github.com/unslothai/unsloth@${UNSLOTH_REF}" \ - "timm>=1.0.11" "addict" + `# structlog is a studio backend dep, not an unsloth[huggingface] dep,` \ + `# but unsloth_cli's train / export / chat / list-checkpoints all import` \ + `# studio.backend.core.*, so without it every one of them dies on` \ + `# ModuleNotFoundError.

Selection was a pure ceiling (smallest baked version >= the request) and ignored that vLLM is version-locked to transformers, so two of the four baked sidecars could not be imported by the baked vLLM 0.26.0 at all: 4.57.6 ImportError: Support for Transformers v4 is deprecated and was removed in vLLM v0.24.0 5.3.0 ImportError: cannot import name 'ALLOWED_LAYER_TYPES' from transformers.configuration_utils Those two are exactly the ones the common pins select. 241 notebooks pin 4.48/4.52.3/4.55.4/4.56.1/4.56.2/4.57.x and land on the 4.57.6 sidecar, 13 pin 5.2.0/5.3.0 and land on the 5.3.0 sidecar. All 254 died at `from unsloth import FastModel`, before the first model cell.

Which versions clear the floor is measured, not hardcoded: the build imports vllm.transformers_utils.config under every candidate sidecar, deletes the ones that raise, and records the lowest survivor. That is the vLLM module which reads the transformers API, it reproduces both failures, and it imports without a GPU, which matters because the build host has none. A request below the floor is clamped up to the lowest eligible sidecar, the closest version to the notebook's pin this image can actually run; a request above every sidecar still falls through to the baked transformers. Measured on the rebuilt image: sidecars 5.5.0 and 5.10.2 survive, floor 5.5.0, tf-sidecars drops from 250M to 123M, and all 13 distinct transformers pins found across the 433 shipped notebooks now reach `from unsloth import FastModel`.

Across the 433 shipped notebooks that left the training half wide open: trl 382 pin an older release, 378 of them ending the install cell with `pip install --no-deps trl==0.22.2`, against a baked trl 0.24.0 torchao 273 reinstall it and 2 pin 0.15.0, replacing 0.17.0+cu128 torchcodec 92 reinstall it and 26 pin 0.5 or 0.7.0, replacing the 0.11.0+cu128 wheel the Dockerfile pairs with torch 2.11 datasets 254 reinstall it, observed falling from 4.3.0 to 3.0.0 peft 225 reinstall it, observed falling from 0.19.1 to 0.14.0 accelerate 225 reinstall it hf hub 240 reinstall it and tokenizers 64, both version-locked to transformers and shipped in matched copies inside every sidecar So every notebook run mutated the stack the image was validated with, while the shim printed that it was keeping the baked versions. The membership criterion is "replacing this invalidates the tested stack or breaks unsloth", not "a notebook mentions it": snac, causal-conv1d, mamba-ssm, omegaconf, protobuf, sentencepiece and the rest still install normally. Verified in the rebuilt image by running the Gemma3 (270M) install cell verbatim: trl 0.24.0, peft 0.19.1, datasets 4.3.0, accelerate 1.14.0, torchao 0.17.0+cu128, transformers 5.14.1 and huggingface_hub 1.24.0 are all unchanged afterwards, the requested transformers pin is still recorded for the sidecar, and a package the image does not bake still installs. The existing shim tests used peft as their "unprotected package" sentinel, so they move to snac. --- docker/unsloth_pip_shim.py | 42 +++- .../test_docker_pip_shim_training_stack.py | 196 ++++++++++++++++++ tests/python/test_unsloth_pip_shim.py | 108 +++++----- 3 files changed, 289 insertions(+), 57 deletions(-) create mode 100644 tests/python/test_docker_pip_shim_training_stack.py diff --git a/docker/unsloth_pip_shim.py b/docker/unsloth_pip_shim.py index 5d793303c7..35bc2ffe29 100644 --- a/docker/unsloth_pip_shim.py +++ b/docker/unsloth_pip_shim.py @@ -11,9 +11,15 @@ carefully-resolved cu128 torch/vLLM/transformers stack: * `transformers==X` -> NOT installed into the base venv.

The sync backgrounds a GitHub refresh child and the parent exits immediately, firing its `trap finalize EXIT` (Colab intro strip plus categorized view rebuild) while the child is concurrently cp -a'ing refreshed notebooks into the same tree and rewriting the same state file. Six identical fresh-container boots reported cleaned 337/311/316/277/297/360 notebooks, and one of them published a categorized view holding 176 of 359 notebooks because both processes tore down and rebuilt the symlink farm at once. The lost writes are permanent: 222 to 309 recorded hashes no longer matched the file on disk, so those notebooks were treated as user-edited and skipped by every later strip, which is where 10 of the 23 notebooks still carrying the Colab intro came from. Keep the refresh detached, which is the whole point of it, and fix the ordering instead. One exclusive flock covers a whole invocation so the child cannot start until the parent has exited, the parent runs the finalize explicitly before it forks so the order holds even where flock is missing, the finalize is run-once, and the child re-arms it only when the refresh actually copied something. The strip itself only inspected cells[0], which missed 23 of the 433 shipped notebooks: 21 put the Colab badge in cells[0] and the sentence in cells[1] (Advanced_Llama3_2_(3B)_GRPO_LoRA, Falcon_H1-Alpaca, gpt-oss-(20B)-GRPO and friends), and 2 (NeMo-Gym-*) wrap the sentence in a single-line HTML comment. Scan the leading markdown block instead, stopping at the first code cell so it can never reach prose between code cells, and match the closed single-line comment form. The strip stays idempotent and leaves the content signature of all 433 notebooks unchanged, so the boot refresh does not re-copy and re-strip them forever. Measured on the rebuilt image: ten consecutive fresh-container boots all report cleaned 536 notebook(s) and view 359 notebooks in 26 folders, 0 of 433 notebooks retain the Colab intro (was 23), 0 recorded hashes mismatch (was 222 to 309), and a second boot on the same volume is a no-op. --- docker/unsloth_nb_strip_colab.py | 55 +++++-- docker/unsloth_sync_notebooks.sh | 75 ++++++++- .../test_docker_nb_strip_colab_scope.py | 152 ++++++++++++++++++ tests/python/test_docker_nb_sync_race.py | 136 ++++++++++++++++ 4 files changed, 407 insertions(+), 11 deletions(-) create mode 100644 tests/python/test_docker_nb_strip_colab_scope.py create mode 100644 tests/python/test_docker_nb_sync_race.py diff --git a/docker/unsloth_nb_strip_colab.py b/docker/unsloth_nb_strip_colab.py index 95b89a72f0..4ffa67a0a1 100644 --- a/docker/unsloth_nb_strip_colab.py +++ b/docker/unsloth_nb_strip_colab.py @@ -33,11 +33,31 @@ _INTRO_PREFIX = "to run this, press" _WIDGET_VIEW_MIME = "application/vnd.jupyter.widget-view+json" +def _is_intro_line(line): + """True for the Colab run announcement in either shipped spelling. + + Most notebooks open the line with the sentence itself, but two (NeMo-Gym-*) + ship it inside a single-line HTML comment: + + + + Only a comment that OPENS AND CLOSES on the same line is matched, so + dropping it can never leave a dangling `"): + return stripped[4:-3].strip().lower().startswith(_INTRO_PREFIX) + return False + + def _strip_lines(lines): """Drop the intro line (and an immediately-following blank).

A second case covers the other half of that contract, which is what a bare venv actually hits: with nothing protected installed the install must still be forwarded, just without the pair. test_select_cuda_jit_tools.sh stages libnvrtc as symlinks and asserts through readlink, because retargeting that symlink is what the function under test does. git-bash copies instead of symlinking unless MSYS=winsymlinks:nativestrict and the user is elevated, so readlink comes back empty and all 14 assertions fail on both Windows runners, taking tests/run_all.sh down with them for any Windows contributor. The code only ever runs inside a Linux container, so probe for real symlink support and skip when it is absent rather than assert something the filesystem cannot represent. Verified: the shim suite is 87 passed / 2 skipped in both a bare venv and a full one; the shell suite still reports 14 passed on Linux and skips with exit 0 under a simulated no-symlink filesystem. --- tests/python/test_unsloth_pip_shim.py | 41 ++++++++++++++++++++++++-- tests/sh/test_select_cuda_jit_tools.sh | 18 +++++++++++ 2 files changed, 57 insertions(+), 2 deletions(-) diff --git a/tests/python/test_unsloth_pip_shim.py b/tests/python/test_unsloth_pip_shim.py index 0573efcf31..dd993898f3 100644 --- a/tests/python/test_unsloth_pip_shim.py +++ b/tests/python/test_unsloth_pip_shim.py @@ -511,9 +511,36 @@ def _raw_execd(shim, tool, args): return exc.argv[exc.argv.index("install") + 1 :] -def test_forwarded_install_carries_protected_constraints(shim): +class _FakeDist: + """Minimal stand-in for an importlib.metadata Distribution.""" + + def __init__(self, name, version): + self.metadata = {"Name": name} + self.version = version + + +def _fake_distributions(monkeypatch, *pairs): + """Pin what _protected_constraints_file sees as INSTALLED. + + It reads the ambient environment via importlib.metadata.distributions, so + without this the outcome depends on whatever happens to be in the venv: + with no protected package installed it correctly returns None (see its + docstring) and no --constraint pair is appended.

Publish through a same-dir dot-prefixed temp plus an atomic rename, and re-read the hash once the staging copy is complete (the earlier check sits before middle_unchanged, a python subprocess, so the window was most of the loop). A single-file bind mount cannot be renamed over, so that path falls back to the previous copy. Notebook sync, first boot. A pre-existing file whose bytes already match the baked template fell through to cp -a, which is --preserve=all: as root that stamps root:root, the baked mode and the build mtime onto a bind-mounted host file and locks its owner out of editing it. Record it as managed instead. The hash is identical, so the state file is byte-for-byte what the copy wrote. unsloth-studio-update. The post-update import check only warned, then the default restart replaced a process that was serving fine with one known not to import. supervisord retries startretries times, lands in FATAL and never leaves it on its own, so the container serves nothing until someone execs in. Keep the running service and exit non-zero with the remedy. unsloth-llama-update --check. resolve_latest swallows every failure into an empty string, which fell into the "up to date" branch and exited 0, so the command reported a state it could not observe. Report UNKNOWN and fail. unsloth-llama-update rollback. The in-place restore iterates the backup's entries, so a file the new release introduced survives it and the restored tree is mixed-version; ggml dlopens every libggml-*.so next to the binaries. Clear the install dir before restoring, gated on the drain having completed, because before that an entry there can still be the only copy of an old file. docker-publish ref freeze. git ls-remote exits 0 whether or not a ref matched, so a non-zero exit means the remote was never reached. That exit was lost twice over: first element of a pipeline, and a run step with no explicit shell runs under bash -e without pipefail. The step exited 0 and published ref=main, which the amd64, arm64 and Studio builds each resolve again, so one multi-arch tag could carry different revisions. Fail the prepare job instead, keeping the passthrough for the reachable-but-no-match case it was written for. Jupyter output select. lastPointerOutput was only replaced by another pointer-down, but J/K/arrow cell navigation fires none, so Ctrl/Cmd+A on a later cell selected the previously clicked output and suppressed notebook:select-all; after a re-run the node is detached and the chord did nothing at all. Revalidate the remembered output (still in the document, still in the active cell) before using it as the fallback. Tests: four static guards in test_docker_nb_sync_race.py, a new behavioural test_docker_update_helpers.py driving both helpers with stub pip, supervisorctl and mv, a new test_docker_publish_ref_freeze.py that executes each resolver step under bash -e with a failing ls-remote, and a source check in validate_studio_features.py. Each fails against the code before this change; the interrupted-drain case also fails against the unconditional form of the rollback fix. --- .github/workflows/docker-publish.yml | 29 +- .../unsloth_labext/src/outputSelect.ts | 16 +- docker/unsloth_llama_update.sh | 27 +- docker/unsloth_studio_update.sh | 10 +- docker/unsloth_sync_notebooks.sh | 42 ++- tests/python/test_docker_nb_sync_race.py | 56 ++++ .../python/test_docker_publish_ref_freeze.py | 132 +++++++++ tests/python/test_docker_update_helpers.py | 250 ++++++++++++++++++ tests/validate_studio_features.py | 9 + 9 files changed, 558 insertions(+), 13 deletions(-) create mode 100644 tests/python/test_docker_publish_ref_freeze.py create mode 100644 tests/python/test_docker_update_helpers.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index d6f9a1d905..0382f3dc51 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -105,7 +105,17 @@ jobs: if printf '%s' "$REF" | grep -Eq '^[0-9a-f]{40}$'; then SHA="$REF" else - SHA="$(git ls-remote https://github.com/unslothai/unsloth "$REF" | awk 'NR==1{print $1}')" + # ls-remote exits 0 whether or not a ref matched, so a non-zero exit + # means we never reached the remote.

The runner's default `bash -e` shell takes sed's exit status, so an unreachable github.com left TAG empty and the step published the mutable `latest`. Both arch legs re-resolve that through fetch_llama_prebuilt.py and Dockerfile.studio resolves it a third time, so a release cut mid-run can put different llama.cpp bundles under one manifest. Capture the redirect first and fail the job when it is missing or does not land on a release tag, matching the three ref resolvers below it. unsloth_nb_strip_colab.py: strip_notebook read, parsed and then unconditionally os.replace'd. The refresh child re-arms finalize after the entrypoint has execed the container command, so JupyterLab is already serving the tree and a save landing in that window was destroyed, after which migrate recorded the cleaned hash and marked the notebook pristine forever. Re-read the hash once the staged copy is complete and drop it when the file moved, the same rule the refresh publish in unsloth_sync_notebooks.sh already follows. unsloth_nb_view.py: ownership for the view teardown accepted any symlink target under DEST, but every link the tool creates points at DEST/nb. A shortcut the user made in the landing dir to their own file elsewhere in the checkout was therefore classified as ours and deleted on the next boot. Key ownership on DEST/nb instead. cellNav.ts: the edit-mode boundary test compared the cursor line against editor.lineCount, both logical, while JupyterLab wraps markdown and raw editors by default (StaticNotebook.defaultEditorConfig). A one-line markdown header renders as several visual rows, so every arrow left the cell and the wrapped rows could not be reached. Ask CodeMirror whether it can still move one visual line (EditorView.moveVertically, compared by coordsAtPos top) and keep the logical test as the fallback for a non-CodeMirror editor. New tests: 12 passed / 8 failed before, 20 passed / 0 failed after. --- .github/workflows/docker-publish.yml | 24 ++- docker/jupyter/unsloth_labext/src/cellNav.ts | 38 ++++- docker/unsloth_nb_strip_colab.py | 11 ++ docker/unsloth_nb_view.py | 28 ++-- tests/python/test_docker_labext_cell_nav.py | 73 +++++++++ .../python/test_docker_nb_strip_colab_race.py | 139 ++++++++++++++++++ tests/python/test_docker_nb_view_ownership.py | 118 +++++++++++++++ .../python/test_docker_publish_ref_freeze.py | 90 ++++++++++++ 8 files changed, 497 insertions(+), 24 deletions(-) create mode 100644 tests/python/test_docker_labext_cell_nav.py create mode 100644 tests/python/test_docker_nb_strip_colab_race.py create mode 100644 tests/python/test_docker_nb_view_ownership.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 0382f3dc51..d91f61a14b 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -82,12 +82,26 @@ jobs: run: | TAG="$INPUT_TAG" if [ -z "$TAG" ]; then - TAG="$(curl -fsSL -o /dev/null -w '%{url_effective}' \ - https://github.com/unslothai/llama.cpp/releases/latest \ - | sed -n 's#.*/releases/tag/##p')" + # Same rule as the three ref resolvers below.
