AttributeError: '_LazyAutoMapping' object has no attribute '_mapping'

[BeaBea1234]

For

from transformer.models.auto.modeling_auto import MODEL_MAPPING

I get the following error:

AttributeError: '_LazyAutoMapping' object has no attribute '_mapping'

The _LazyAutoMapping class does indeed not have the attribute _mapping (see https://github.com/huggingface/transformers/blob/master/src/transformers/models/auto/auto_factory.py). However, it has a function def iter(self) that is supposed to return iter(self._mapping.keys()), which does not exist in init(). Am I missing something here or is this an error that needs to be fixed?

This is the error message:

 File "/content/drive/MyDrive/SharedColabNotebooks/Code/transformersum/src/main.py", line 8, in <module>
    from extractive import ExtractiveSummarizer

       return iter(self._mapping.keys())
AttributeError: '_LazyAutoMapping' object has no attribute '_mapping'

Any help is greatly appreciated!
