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.
