73973435ad* Require a found ROCm DLL before forcing BNB_ROCM_VERSION in Studio paths main.py previously set BNB_ROCM_VERSION=72 whenever HIP_PATH or ROCM_PATH was set, and the training worker fell back to a blind 72 when DLL detection found nothing. On a Windows machine with the AMD HIP SDK installed but CUDA or CPU torch, that forces a ROCm backend onto a non-ROCm bitsandbytes wheel, which raises at import. Both paths now only write the override when a libbitsandbytes_rocm DLL actually exists (or a seeded value is already present), matching the strict gates in unsloth/import_fixes.py. Also removes four redundant local import shutil statements in unsloth/save.py that shadow the module-level import, the same pattern that caused the UnboundLocalError fixed in #6149. * Worker: gate the BNB override on a found ROCm DLL, preserving seeded marker Review follow-ups: track _found_rocm_bnb in the worker like main.py so a ROCm DLL with an unparsable name still gets the seeded or 72 fallback, and skip the env write entirely when no DLL exists so a seeded value keeps its sitecustomize marker and stays redetectable by later import fixes. |
