train_MambaDFuse.py: error: unrecognized arguments: --local-rank=1

[Jamie-Cheung]

If your script expects --local-rank argument to be set, please
change it to read from os.environ['LOCAL_RANK'] instead. See
https://pytorch.org/docs/stable/distributed.html#launch-utility for
further instructions

Could you tell me how to solve this problem? Thank you for your time.

I also encountered the same problem. Have you solved it

好像是因为博主代码是多GPU训练，而自己在跑的时候只有一个GPU的话是单GPU训练，需要修改成单GPU训练
