I’m try run
torch.distributed.init_process_group('nccl', world_size=2, rank=0, init_method='file://' + os.path.abspath('./dummy'))

inside docker container, that’s started with command:
docker run --runtime=nvidia --network="host" --shm-size 1g -v [from]:[to] -i -t [image] /bin/bash

But have RuntimeError:
RuntimeError: Timed out initializing process group in store based barrier on rank: 0, for key: store_based_barrier_key:1

Can you help me please?
