Comment-only pass over the PR's own files. No executable line changes. - Dockerfile / Dockerfile.studio: drop the decorative stage banner rules, the stale "5)" / "6)" step numbering, and the entrypoint pre-flight list that restated (and had drifted from) entrypoint.sh's own accurate header. Cut the llama.cpp asset bullet list that repeats fetch_llama_prebuilt.py's docstring and the structlog rationale already spelled out at the install site. - entrypoint.sh / studio_launch.sh: fold the section banners into the explanation lines that follow them. - docker-publish.yml: remove the comment rule lines around the job headers. - validate_studio_features.py: same for the numbered section headers. - smoke_test.py: drop the stale "~125M params" note on a 1B model. - unsloth_branding.py, unsloth_nb_view.py, unsloth_nb_pip_magic.py, colabTitle.ts: remove comments that restate the adjacent line.

|
|
# Unsloth + unsloth-zoo for every current NVIDIA arch (Turing -> Blackwell),
|
|
# on linux/amd64 and linux/arm64.
|
|
#
|
|
# Why it works:
|
|
# * cu128 wheels ship native SASS (no PTX), verified via `cuobjdump --list-elf`:
|
|
# amd64: sm_70 sm_75 sm_80 sm_86 sm_90 sm_100 sm_120
|
|
# arm64: sm_80 sm_90 sm_90a sm_100 sm_100a sm_120 sm_120a
|
|
# * SASS is forward-compatible within a major: sm_86->sm_89 (Ada),
|
|
# sm_100->sm_103 (B300/GB300), sm_120->sm_121 (DGX Spark/GB10), so every
|
|
# non-Jetson GPU on https://developer.nvidia.com/cuda/gpus runs precompiled
|
|
# SASS (torch, llama.cpp, source-built ops).
|
|
# * Triton kernels JIT per-device at first run; the bundled cu12.8 ptxas/NVRTC
|
|
# cannot emit compute_103/compute_121, so the cu13 override below handles
|
|
# amd64 sm_103 and arm64 sm_121 (SASS still runs there via forward-compat, so
|
|
# only JIT-heavy paths need it).
|
|
# * Rare source builds compile against
|
|
# TORCH_CUDA_ARCH_LIST="7.5;8.0;8.6;8.9;9.0;10.0;12.0+PTX"; the host GPU is
|
|
# irrelevant, nvcc emits whatever the arch list says.
|
|
#
|
|
# Cross-arch build (arm64 / sm_121): built via QEMU binfmt on an x86_64 host
|
|
# (`docker run --privileged --rm tonistiigi/binfmt --install all` once, then
|
|
# `docker buildx build --platform linux/arm64 ...`). QEMU is build-time only;
|
|
# the image runs natively on aarch64. xformers has no cu128 aarch64 wheel, so
|
|
# arm64 falls back to Unsloth's SDPA (~5-10% slower, functionally complete).
|
|
#
|
|
# Build host needs Docker buildkit + buildx, and QEMU binfmt for arm64-on-x86_64;
|
|
# nvidia-container-toolkit only for test-time `--gpus all`. No GPU at build time.
