When a user has HIP_VISIBLE_DEVICES set in their shell (e.g. "1" to select GPU 1) but detect_hardware() has not yet run in the Studio parent process, IS_ROCM is still False. _get_parent_visible_gpu_spec() was gated on IS_ROCM so it fell through to CUDA_VISIBLE_DEVICES (unset), saw all physical GPUs, and auto-selected index 0. apply_gpu_ids then overwrote HIP_VISIBLE_DEVICES with "0", making the intended GPU invisible to ROCm torch in the worker, which triggered the "no usable HIP accelerator" error (issue #5180). Apply the same _inherits_rocm_visibility pattern already used in apply_gpu_ids: check for HIP_VISIBLE_DEVICES / ROCR_VISIBLE_DEVICES in the environment regardless of IS_ROCM so the correct GPU index is preserved. |
