Hey @Purvak-L, you can cd to the NCCL submodule in the third party folder in https://github.com/pytorch/pytorch/tree/master/third_party/nccl 22 and manually update the nccl module there.
Another option is to install 2.7.6 locally and set USE_SYSTEM_NCCL=1 when building PyTorch. See this issue: https://github.com/pytorch/pytorch/issues/32286 33
