请问在sat下如何进行多机训练？需要修改哪些配置呢

[QingQingS]

`#! /bin/bash

echo "RUN on $(hostname), CUDA_VISIBLE_DEVICES=$CUDA_VISIBLE_DEVICES"

run_cmd="PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True torchrun --standalone --nproc_per_node=8 train_video.py --base configs/test_cogvideox_5b.yaml configs/sft.yaml --seed $RANDOM"

echo ${run_cmd} eval ${run_cmd}

echo "DONE on hostname"` 启动命令应该怎样写呢？ sft.yaml 跟cogvideo5b.yaml里配置需要修改么？
