AttributeError: 'DaViT' object has no attribute '_initialize_weights'

Florence2LanguageForConditionalGeneration has generative capabilities, as prepare_inputs_for_generation is explicitly defined. However, it doesn't directly inherit from GenerationMixin. From 👉v4.50👈 onwards, PreTrainedModel will NOT inherit from GenerationMixin, and this model will lose the ability to call generate and other related functions.

• If you're using trust_remote_code=True, you can get rid of this warning by loading the model with an auto class. See https://huggingface.co/docs/transformers/en/model_doc/auto#auto-classes
• If you are the owner of the model architecture code, please modify your model class such that it inherits from GenerationMixin (after PreTrainedModel, otherwise you'll get an exception).
• If you are not the owner of the model architecture class, please contact the model code owner to update it.

Hello, i am a very new developper and was wondering what could cause this issue if anyone could help. Thanks!

The problem can be solved by downgrading Transformers from 4.52.1 to 4.51.1
pip install Transformers==4.51.1 -U
