Impact: CI only (ROCm distributed test shards) Risk: low What Gate test/distributed/test_c10d_nccl4py.py on not TEST_WITH_ROCM so the whole file is skipped on ROCm runners, as it was before. Why nccl.core imports fine on ROCm, so the existing HAS_NCCL4PY / torch.cuda.is_available() guards let these tests run there — but the backend dlopens libnccl.so.2 on first use, which only NVIDIA ships. #195904 changed the surro…
