[Docs] How do backend_args work?

[Data-drone]

📚 The doc issue

I can't seem to find any documentation on how backend_args work along with allowable values?

Suggest a potential alternative/fix

mmengine documentation should either have some examples of valid backend_args configurations aside from just the Ceph 'petrol' example in some of the detection files

Hi @Data-drone , thanks for your feedback. backend_args is used to decide which backend should be used and to initialize the corresponding Backend. More details can be found at here.

BTW, I will provide a document for backend usage soon.

is it possible to remove the petrel_backend defaults to another branch or as an added extra? I keep having issues with:

ModuleNotFoundError: No module named 'petrel_client'
