Hi,

This could indicate one of the nodes was for some reason irresponsive during the distributed initialization.

In order to debug those types of errors, I generally use the environment variable NCCL_DEBUG=INFO to get more information about what's going on within NCCL.

So if you get those errors more regularly, could you please run the script with

NCCL_DEBUG=INFO python run_with_submitit.py

and share the full logs?

Given that I believe this was a one-off error I'm closing this issue, but please let us know if you keep facing this problem.
