How to train a model in the same terminal when I used DDP training？

[szhang963]

I need to open 8 terminals when I used DDP training.It is so troubling.What method can I use in one terminal？

Use tmux to open more sessions in one terminal.

You can use the command like this

python3 -m torch.distributed.launch --nproc_per_node 4 --master_port=9495 xxx.py

This command will start a DDP without using 8 terminals

You can use tmux to do so.
