Who can help?

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

Right now any command with --deepspeed /path/to/json will fail and throw the following error

--deepspeed: invalid Dict value

This is reported in #24549 (comment) but the merged fix #24574 does not resolve this.
In fact the deepspeed: Union[str, Dict] field in training_args.py still raise the error when the deepspeed is passed as the string. This seems to be a limitation of python dataclass.

Expected behavior

deepspeed flag should support string.

Yes, this has been broken by #24550 again...

@sgugger Any chance this got broken once again on the latest version (4.53.2)?
