The nccl test output is as follows:

Does it mean that the nccl setup is well done?
By the way, I’ve noticed the nccl version in my docker image is 2.7.8, but the runtime error says NCCL version is 2.4.8. It seems that PyTorch has another version installed internally, will the version mismatch lead to an error?
Thank you all for your time!
