when I launch multi gpu train use this command:
python -m torch.distributed.launch --nproc_per_node=2 /path_to_maskrcnn_benchmark/tools/train_net.py --config-file "path/to/config/file.yaml"
and it's run in docker container env, there are have two p40 in docker, but it seems that only one GPU is being used.

and there are actually two processes running

What could be the reason?
