Addresses review findings from parallel reviewers on PR #4720: - install.sh: add _has_usable_nvidia_gpu() helper requiring nvidia-smi -L to actually list a GPU before treating the host as NVIDIA. Fixes the stale-nvidia-smi-on-PATH regression where AMD-only hosts fell into the CUDA branch. - install.sh: fix hipconfig awk blocks to propagate a non-zero exit code when the output is not a recognisable version string, so the ||-chain continues to dpkg-query / rpm instead of terminating early. - install.sh: fail-closed on Radeon wheel fallback. When torch, torchvision or torchaudio is missing from the Radeon repo for the active Python tag, fall back to the standard ROCm index instead of silently mixing Radeon wheels with PyPI defaults. Quote all wheel arguments individually so wheel filenames cannot be word-split or glob-expanded. - install_llama_prebuilt.py: detect_host() now requires nvidia-smi -L to list a GPU before setting has_physical_nvidia. Routes AMD ROCm hosts with a broken leftover nvidia-smi to the ROCm path instead of misclassifying them as NVIDIA. - install_llama_prebuilt.py: scan upstream assets for any rocm-<version> prebuilt instead of hard-coding rocm-7.2, so ROCm 6.x / 7.0 / 7.1 / 7.3+ users pick up a matching upstream prebuilt when one exists. - install_llama_prebuilt.py: validate_server() adds --n-gpu-layers 1 for linux-rocm and windows-hip hosts, so new HIP prebuilts are preflighted on the GPU path instead of passing validation on CPU only. - install_llama_prebuilt.py: restore the published windows-cpu fallback for AMD Windows hosts without a HIP prebuilt so hash-approved bundles are still preferred over the raw upstream CPU asset. - install_python_stack.py: drop the /opt/rocm / hipcc gate in _ensure_rocm_torch() and rely on _has_rocm_gpu(). Runtime-only ROCm installs (package-managed minimal installs, Radeon software) that ship amd-smi / rocminfo without hipcc can now repair a CPU-only venv via "unsloth studio update". Adds an explicit IS_WINDOWS / IS_MACOS guard. - studio/backend/utils/hardware/amd.py: honour HIP_VISIBLE_DEVICES / ROCR_VISIBLE_DEVICES / CUDA_VISIBLE_DEVICES in get_primary_gpu_utilization(). A process restricted to GPU 2 now reports metrics for GPU 2 instead of physical GPU 0. Tighten the plain bytes unit detection to an explicit allowlist. - studio/backend/utils/hardware/hardware.py: route get_backend_visible_gpu_info()'s backend_cuda_visible_devices field through a helper that reads HIP_VISIBLE_DEVICES on ROCm. Drop the unconditional "(rocm=False)" suffix in apply_gpu_ids() logs. |
