When does this happen?

IF AutoProcessor.from_pretrained fails with AttributeError: 'dict' object has no attribute 'model_type' when loading a local model in transformers v4.57.2.

How others solved it

THEN Upgrade transformers to a version >4.57.2 where the fix is applied, or manually patch tokenization_utils_base.py: change `if _is_local and _config.model_type not in [` to `if _is_local and _config.get('model_type') not in [` or use dictionary access `_config['model_type']`. As a temporary workaround, set the `transformers_version` key in the local model's config.json to "4.57.2" to bypass the version check, though this may introduce compatibility risks.
