* Use prebuilt llama.cpp for unsloth studio setup
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix 3 issues that cause unnecessary fallback to source build
1. Make filelock import optional -- environments without filelock
(e.g. minimal installs) crashed at import time instead of
gracefully skipping the lock.
2. Use already-verified converter script from the hydrated source
tree instead of re-downloading from raw.githubusercontent.com
with no checksum. Adds symlink with copy fallback for the
legacy filename.
3. Initialize $SkipPrebuiltInstall in setup.ps1 before first use
to prevent potential uninitialized variable errors.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Keep network fallback in ensure_converter_scripts
Prefer the local verified copy from the hydrated source tree, but
retain the original network download as a fallback if the file is
missing. Create the legacy hyphenated filename as a symlink with a
copy fallback instead of writing a second full copy.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix 4 bugs in source-build fallback and binary_env paths
- setup.ps1: Replace git pull + checkout FETCH_HEAD with fetch + checkout -B
to avoid detached HEAD state that breaks re-runs. Use pinned tag in both
fetch and clone paths.
- setup.sh: Move rm -rf after cmake/git prerequisite checks so a missing
tool no longer deletes the existing install. Add --branch tag to clone.
- install_llama_prebuilt.py: Add binary_path.parent to Linux LD_LIBRARY_PATH
in binary_env() so bundled .so files in build/bin are found even without
RPATH, matching the existing Windows PATH logic.
- Add test for binary_env LD_LIBRARY_PATH on Linux.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Handle unresolved "latest" tag in source-build fallback clone
When tag resolution fails and the requested tag is "latest", both
setup scripts now omit --branch from git clone so the default branch
is cloned instead of failing on a nonexistent "latest" branch/tag.
Similarly, the PS1 fetch path fetches the default ref when the tag
is "latest".
* Resolve actual latest ggml-org tag instead of using literal "latest"
When both Python tag resolution attempts fail and the requested tag
is "latest", query the GitHub API for the actual latest release tag
from ggml-org/llama.cpp (e.g. b8508) instead of passing the literal
string "latest" to git clone --branch, which would fail since no
such branch/tag exists.
setup.sh uses curl + python json parsing; setup.ps1 uses
Invoke-RestMethod. Both fall back to the raw requested tag if the
API call also fails.
* Try Unsloth release repo before ggml-org when resolving latest tag
When falling back to the GitHub API to resolve "latest", query the
Unsloth release repo (unslothai/llama.cpp) first since it has the
prebuilt binaries pinned to tested tags. Only fall back to
ggml-org/llama.cpp if the Unsloth repo query fails.
* Add comprehensive sandbox tests for PR #4562 bug fixes
35 tests covering all fixes across platforms:
- binary_env cross-platform (Linux LD_LIBRARY_PATH, Windows PATH,
macOS DYLD_LIBRARY_PATH) with edge cases (dedup, ordering, existing paths)
- resolve_requested_llama_tag (concrete, latest, None, empty)
- setup.sh logic via subprocess: prereq check ordering (cmake/git missing
preserves install), pinned tag in clone, fetch+checkout -B pattern,
fetch failure warns instead of aborting
- "latest" tag resolution fallback chain (Unsloth API -> ggml-org ->
raw) with mock curl: success, failure, malformed JSON, empty body,
empty tag_name, env overrides
- Source code pattern verification for both .sh and .ps1 files
All 138 tests pass in isolated uv venv.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Add binary_path.parent to macOS DYLD_LIBRARY_PATH in binary_env
macOS prebuilt .dylib files are overlaid into build/bin (same as
Linux), but binary_env only added install_dir to DYLD_LIBRARY_PATH.
Add binary_path.parent so the loader can find sibling dylibs even
without embedded loader paths.
Mirrors the existing fix for Linux LD_LIBRARY_PATH and the Windows
PATH pattern.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Guard --branch when resolved tag is "latest"; fix broken test assertion
When all API fallbacks fail and the tag stays as literal "latest",
omit --branch from git clone (clones default branch instead of
failing). Both setup.sh and setup.ps1 now check for "latest" before
passing --branch to git clone/fetch.
Also fix test_setup_ps1_clone_uses_branch_tag which used Python
tuple syntax (assert "x", "y" in z) that always passes. Changed to
assert "x" in z and "y" in z.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix macOS DYLD trailing colon, install_lock no-op, and debug log
- binary_env macOS: use dedupe_existing_dirs instead of raw string
concatenation. Eliminates trailing colon in DYLD_LIBRARY_PATH
(which causes dyld to search CWD for libraries) and deduplicates
when binary_path.parent == install_dir. Now consistent with the
Linux and Windows branches.
- install_lock: when filelock is not installed, use os.O_CREAT|O_EXCL
as a fallback exclusive file lock with timeout, instead of yielding
with no locking. Prevents concurrent installs from corrupting each
other's staging directories.
- setup.ps1: remove [DEBUG] log line that printed to every user on
every Windows setup run.
* Add stale-lock detection and atomic clone-then-swap
install_lock fallback (no filelock): write PID to lock file and
check if the holder process is still alive on contention. Dead PIDs
(ProcessLookupError) and unreadable lock files trigger immediate
cleanup. Live processes owned by other users (PermissionError) are
correctly recognized as alive -- the lock is not removed.
setup.sh/setup.ps1 source-build: clone into a temporary directory
first, then swap into place only on success. If git clone fails,
the existing install is preserved instead of being deleted by the
premature rm -rf.
* Remove redundant upstream_tag != release_tag check
load_approved_release_checksums compared checksums.upstream_tag
against the Unsloth release_tag, which are different namespaces
(upstream ggml-org tag vs Unsloth published tag). This only worked
because both happened to be "b8508" by convention. Would break if
Unsloth ever uses a different release naming scheme.
The existing check at parse_approved_release_checksums (line 950)
already validates the release_tag field correctly.
* Fix lock TOCTOU race and build-in-temp-dir swap
install_lock fallback: add os.fsync(fd) after writing PID to ensure
the PID is visible to racing processes before they check. Treat
empty lock files (PID not yet written) as "wait and retry" instead
of stale, closing the window where two processes could both see an
empty file, both unlink it, and both acquire the lock.
setup.sh/setup.ps1 source-build: clone AND build in a temp directory
(LLAMA_CPP_DIR.build.$$). Only swap into the final LLAMA_CPP_DIR
after the build succeeds. If clone or cmake or build fails, the temp
dir is cleaned up and the existing working install is preserved.
Previously, rm -rf ran after clone but before build, destroying the
existing install even if the build later failed.

This reverts commit 301291d002.
* feat: migrate old .venv layout in install.sh instead of always nuking
* feat: validate old .venv with torch CUDA test before migration, recovery message on launch failure
* fix: try CUDA then fall back to CPU for migration validation
* fix: upgrade unsloth/unsloth-zoo with --reinstall-package on migration to preserve torch
* remove: delete unused unsloth ui command (use unsloth studio instead)
* Fix Windows venv path mismatch between install.ps1, setup.ps1, and studio.py
install.ps1 was creating the venv CWD-relative ($VenvName = "unsloth_studio"),
setup.ps1 was using an absolute path to ".unsloth\studio\.venv", and studio.py
looks for ".unsloth\studio\unsloth_studio". All three paths were different, so
the Windows installer would never produce a working Studio setup.
install.ps1:
- Use absolute $StudioHome + $VenvDir matching the Linux install.sh layout
- Add 3-way migration: old .venv at STUDIO_HOME, CWD-relative ~/unsloth_studio
from the previous install.ps1, or fresh creation with torch validation
- For migrated envs, upgrade unsloth while preserving existing torch/CUDA wheels
- Set SKIP_STUDIO_BASE=1 before calling setup.ps1 (matches install.sh behavior)
- Fix launch instructions to use the absolute venv path
setup.ps1:
- Change $VenvDir from ".unsloth\studio\.venv" to ".unsloth\studio\unsloth_studio"
- Add SKIP_STUDIO_BASE guard: error out if venv is missing when called from
install.ps1 (which should have already created it)
- Differentiate "Setup" vs "Update" in banners based on SKIP_STUDIO_BASE
* setup.ps1: unconditionally error if venv missing, matching setup.sh
setup.sh always errors out if the venv does not exist (line 224-228),
telling the user to run install.sh first. setup.ps1 was conditionally
creating a bare venv with python -m venv when SKIP_STUDIO_BASE was not
set, which would produce an empty venv with no torch or unsloth. Now
setup.ps1 matches setup.sh: always error, always point to install.ps1.
* Fix --torch-backend=auto CPU solver dead-end on Linux, macOS, and Windows
On CPU-only machines, `uv pip install unsloth --torch-backend=auto`
falls back to unsloth==2024.8 because the CPU solver cannot satisfy
newer unsloth's dependencies. install.ps1 already solved this with a
two-step approach; this applies the same fix to install.sh and
install_python_stack.py.
install.sh: add get_torch_index_url() that detects GPU via nvidia-smi
and maps CUDA versions to PyTorch index URLs (matching install.ps1's
Get-TorchIndexUrl). Fresh installs now install torch first via explicit
--index-url, then install unsloth with --upgrade-package to preserve
the pre-installed torch. All 5 --torch-backend=auto removed from
primary paths.
install.ps1: add fallback else-branch when TorchIndexUrl is empty,
using --torch-backend=auto as last resort (matching install.sh).
install_python_stack.py: remove unconditional --torch-backend=auto
from _build_uv_cmd. Torch is pre-installed by install.sh/setup.ps1
by the time this runs. Callers that need it can set UV_TORCH_BACKEND.
Both install.sh and install.ps1 now share the same three-branch logic:
migrated env (upgrade-package only), normal (torch-first + index-url),
and fallback (--torch-backend=auto if URL detection fails).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Use --reinstall-package for migrated envs on both Linux and Windows
For migrated environments (moved from legacy venv location),
--reinstall-package is better than --upgrade-package because it forces
a clean reinstall even if the same version is already installed. This
ensures proper .dist-info and .pyc state in the new venv location.
--upgrade-package remains correct for the fresh install path where
torch is already installed and we just want to add unsloth without
re-resolving torch.
* Address review findings: portability, parity, and stale comments
- Replace grep -oP (GNU Perl regex) with POSIX sed in
get_torch_index_url() so the script works on BSD grep (macOS is
already guarded by the Darwin early-return, but Alpine/BusyBox
would silently get the wrong CUDA tag)
- Add LC_ALL=C before nvidia-smi invocation to prevent locale-dependent
output parsing issues
- Add warning on stderr when nvidia-smi output is unparseable, matching
install.ps1's [WARN] message
- Add explicit unsloth-zoo positional arg to install.ps1 migrated path,
matching install.sh (--reinstall-package alone won't install it if it
was never present in the migrated env)
- Fix stale comment in install_python_stack.py line 392 that still
claimed --torch-backend=auto is added by _build_uv_cmd
- Add sed to test tools directory (function now uses sed instead of grep)
* Add --index-url to migrated env path to prevent CPU torch resolution
The migrated path runs uv pip install with --reinstall-package for
unsloth/unsloth-zoo. While uv should keep existing torch as satisfied,
the resolver could still re-resolve torch as a transitive dependency.
Without --index-url pointing at the correct CUDA wheel index, the
resolver would fall back to plain PyPI and potentially pull CPU-only
torch. Adding --index-url $TORCH_INDEX_URL ensures CUDA wheels are
available if the resolver needs them.
Applied to both install.sh and install.ps1.
* Revert --index-url on migrated env path
The original install.ps1 on main already handles the migrated path
without --index-url and it works correctly. --reinstall-package only
forces reinstall of the named packages while uv keeps existing torch
as satisfied. No need for the extra flag.
* Fix unsloth studio update --local not installing local checkout
studio.py sets STUDIO_LOCAL_REPO when --local is passed, but
install_python_stack.py never read it. The update path always
installed from PyPI regardless of the --local flag.
Add a local_repo branch that first updates deps from base.txt
(with --upgrade-package to preserve torch), then overlays the
local checkout as an editable install with --no-deps.

* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix 3 bugs in Q-GaLore optimizer and add weight_quant forward hooks
1. Fix use-after-delete crash: move `del p._saved_data` after the
weight decay block so decoupled weight decay can reference the
current weights correctly (p.data).
2. Fix substring matching in make_q_galore_param_groups: split
parameter names on "." and check exact component matches to
prevent false positives (e.g. "not_q_proj" matching "q_proj").
3. Implement forward pre-hooks for weight_quant: after the optimizer
quantizes weights to INT8, replace p.data with a 1-element
placeholder to free float memory. A register_forward_pre_hook
dequantizes back to float before each forward pass. The trainer
calls install_weight_quant_hooks() when weight_quant is enabled.
4. Update test_weight_decay_uses_saved_data to match the fixed code
path (decoupled decay uses p.data, expected value 2.7). Add
test_weight_quant_hook_restores_float to verify the INT8-to-float
hook round-trip.
All 24/24 Q-GaLore tests pass. Benchmarked on Llama-3.2-1B-Instruct
FFT: Q-GaLore saves 32% VRAM (10.63 -> 7.24 GB) with better loss
convergence (1.3 vs 2.0 at step 100). No regressions in 31-notebook
sweep across Llama, Qwen, Mistral, Phi, Gemma, vision, and GRPO.
* Default weight_quant to False in QGaloreConfig
Benchmarks show weight_quant=True adds ~1 GB on Llama-3.2-1B due to
INT8 copy/scale overhead exceeding savings from the placeholder trick.
Users can still opt in explicitly. The optimizer logic is unchanged.
* Optimize Q-GaLore projector and optimizer step performance
Projector (q_galore_projector.py):
- Use torch.svd_lowrank with oversampling p=10 (Halko et al. 2009) instead
of full SVD for large matrices. Falls back to full SVD when min(m,n) <= 2*rank.
SVD steps are 6-8x faster on Llama-3.2-1B (22s -> 3s for first step).
- Cache the dequantized ortho matrix between project() and project_back() to
avoid redundant dequantization when quant=True.
- Replace F.cosine_similarity with torch.dot for 1-D unit vectors in the
adaptive schedule. Remove unused torch.nn.functional import.
- Use collections.deque(maxlen=queue_size) instead of list with manual pop(0).
Optimizer (q_galore_adamw.py):
- Remove redundant .clone() on dequantized weights (line 151) and on float
data before re-quantization (line 211). _dequantize already returns a fresh
tensor and _quantize/_quantize_stochastic only reads its input.
- Consolidate per-group torch.cuda.synchronize() into a single call after
all param groups complete.
- Use torch.empty instead of torch.zeros for the scalar placeholder tensor
that is never read.
Verified: 24/24 unit tests pass. Llama-3.2-1B 61-step training produces
losses within 0.24% relative diff (correlation >0.9999) of the original.

**Summary:** The existing QAT + LoRA path only applied fake
quantization to the original slow path, but the default is the
fast path that calls unsloth's fast LoRA primitives. This commit
integrates fake quantization into these fast primitives as well,
and add unit tests to assert that fake quantization is actually
taking place.
**Test Plan:**
Unit tests:
```
pytest tests/utils/test_qat.py
```
End-to-end test: https://gist.github.com/andrewor14/6360dd69b5784c71c46e80c14f53e6b6
Full fine-tuning Llama3.1-8B with and without QAT + LoRA on yahma/alpaca-cleaned for 1 epoch:
- Batch size = 8 (no grad accum)
- Learning rate = 2e-4
- Quantization scheme = int4 weight only (with bf16 activations)
Wikitext perplexity:
- Baseline = int4 quantized model finetuned without QAT
- QAT int4 quantized model (with this PR) achieved 33% lower perplexity than the int4 baseline
- QAT int4 quantized model without this PR was worse than the int4 baseline
