in https://github.com/pacman100/DHS-LLM-Workshop/blob/main/chat_assistant/training/utils.py#L182C9-L182C19, what is the reason to set device_map = 'auto'
When I run it with accelerator (with fsdp) I got the error

ValueError: You can't train a model that has been loaded with `device_map='auto'` in any distributed mode. Please rerun your script specifying `--num_processes=1` or by launching with `python {{myscript.py}}`.

Also in here (huggingface/accelerate#1840) it states that it is not compatible with using DistributedDataParallel.
