WebInstall and build a specific NCCL version. To do this, replace the content in the PyTorch’s default NCCL folder ( /pytorch/third_party/nccl) with the specific NCCL version from the NVIDIA repository. The NCCL version was set in the step 3 of this guide. WebNCCL is supported for Allreduce, Allgather, Broadcast, and Alltoall operations. You can enable these by setting HOROVOD_GPU_OPERATIONS=NCCL during installation. NCCL operations are supported on both Nvidia (CUDA) and AMD (ROCm) GPUs. You can set HOROVOD_GPU in your environment to specify building with CUDA or ROCm.
