When does this happen?

IF Mypy reports 'has no attribute' errors on Trainer or PreTrainedModel when importing from top-level transformers module (since v4.51.0) because types are pulled from dummy_pt_objects.

How others solved it

THEN To fix, import directly from submodules: from transformers.trainer import Trainer and from transformers.modeling_utils import PreTrainedModel. Alternatively, library maintainers should add __all__ to exported symbols to resolve type resolution.

Instead of `from transformers import Trainer`, use `from transformers.trainer import Trainer`.
