The error happened when I did multi-node distributed training #180
Description
🐛 Describe the bug
Excuse me. When I enter the command "colossalai run --nproc_per_node 4 --host [host1 ip addr],[host2 ip addr] --master_addr [host1 ip addr] train.py", I got this message: Error: failed to run torchrun --nproc_per_node=4 --nnodes=2 --node_rank=1 --rdzv_backend=c10d --rdzv_endpoint=[host1 ip addr]:29500 --rdzv_id=colossalai-default-job train.py on [host2 ip addr]
What are the configurations I have to set in the train.py you provided with?
