How can I use DDP mode without `torch.distributed.launch` command when I use transformers.Trainer
I checked the historical issues and readed a part of source code. But I didn't find the way out to use DDP without `torch.distributed.launch`. Is there a way to use deepspeed or ddp without modifying the command? Like a field named `strategy: str` to select the way weather I use DDP.

Thank you. I got it.
