Fix: pytorch/pytorch#116977 Nccl 2.19.3 don't exist for cuda 11.8 and cuda 12.1. Refer to https://docs.nvidia.com/deeplearning/nccl/release-notes/rel_2-19-3.html#rel_2-19-3 CUDA 12.0, 12.2, 12.3 are supported. Hence we do manual build. Follow this build process: https://github.com/NVIDIA/nccl/tree/v2.19.3-1?tab=readme-ov-file#build We want nccl version be exactly the same as installed here: https://github.com/pytorch/pytorch/blob/main/.github/scripts/generate_binary_build_matrix.py#L45
