- install.sh: gate the new aarch64 bitsandbytes block on SKIP_TORCH=false --
with --no-torch/UNSLOTH_NO_TORCH (GGUF-only install) it would have pulled
torch back into the venv through bitsandbytes' dependencies.
- studio worker: in the new Spark OOM-guard section, decide
PYTORCH_CUDA_ALLOC_CONF (expandable_segments) BEFORE the guard's first CUDA
touch -- get_device_properties initializes the CUDA allocator, after which
the env var is ignored, and the later `import unsloth`
(patch_dgx_spark_memory_config) is too late for the worker process. Uses
the same CUDA-free nvidia-smi name sniff, append-don't-override, and
UNSLOTH_NO_EXPANDABLE_SEGMENTS opt-out as the library patch. Live-verified
on the N1X: env set while torch.cuda.is_initialized() is still False.
- uninstall.ps1: only run `fuser -k 8888/tcp` in a probed WSL distro when an
Unsloth install actually exists there (checked BEFORE the rm deletes the
marker) -- an unrelated listener on 8888 (e.g. Jupyter) in a clean distro
must survive a Windows-side uninstall. The Unsloth-specific pkills stay
unconditional.
- install.ps1 + uninstall.ps1: persist the chosen WSL distro to
%LOCALAPPDATA%\Unsloth\wsl-distro.txt at install; uninstall reads it
(before removing the directory) and prepends it to the cleanup candidates,
so a custom UNSLOTH_WSL_DISTRO install is cleaned without the env var
being set again at uninstall time.
- provision_llama_cuda.sh: honor UNSLOTH_LLAMA_PR (numeric-validated,
best-effort fetch of pull/N/head after clone) so a provisioned tree
matches a PR pin the way setup.sh does; and require only llama-server in
the main cmake build (mirroring setup.sh), building the helper targets
(llama-cli/quantize/mtmd-cli/gguf-split) best-effort afterwards -- an
older UNSLOTH_LLAMA_TAG pin lacking a newer helper target no longer fails
the whole provision.
Not changed: the "--tauri rejection doesn't restore the venv rollback"
comment is incorrect -- the rejection returns through Exit-InstallFailure,
which itself calls Restore-StudioVenvRollback.
