Ok, let me try to reproduce this error. May I know which GPU you are using and how many GPUs are available on your machine?

Hi, sorry for my late reply. We only got A100 machines so it took a while for me to look for a V100 machine. This bug can be reproduced on torch 1.8 but not torch 1.10. This bug is due to an optional argument in pytorch DistributedDataParallel. This bug will be fixed in #194 .
