AMD's pip index now ships torch==2.11.0+rocm7.13.0 (ROCm 7.13). bitsandbytes auto-detects HIP 7.13 from torch.version.hip and looks for libbitsandbytes_rocm713.dll, which the AMD Windows prerelease wheel does not ship (it only ships rocm72.dll), causing a load error at training start. Fix: - worker.py section 1f: set BNB_ROCM_VERSION=72 (via setdefault) before section 2 ML imports, so bitsandbytes always loads rocm72.dll on Windows ROCm - install_python_stack.py: set BNB_ROCM_VERSION=72 in _install_bnb_windows_rocm() for any post-install imports; update comment to document root cause - tests: 4 new assertions covering the fix (141 passed, 2 skipped) |
