I got the following error when trying to load it using device_map='auto'

    raise ValueError(
ValueError: PhiForCausalLM does not support `device_map='auto'`. To implement support, the model class needs to implement the `_no_split_modules` attribute.

My code is pretty generic so I wouldn't really like to add exceptions for specific models and probably a lot of other people would also benefit if you can add this into the main release? It seems this error is related so I decided to raise a PR myself but I noticed that the _no_split_modules is actually already present so I'm not sure why this occurs.
