When does this happen?

IF Upgrading transformers to 4.50.0 causes Florence2 and similar custom models to fail with ValueError: Unrecognized configuration class when using AutoModelForCausalLM.

How others solved it

THEN Downgrade transformers to version 4.49.0 or wait for an upstream fix. As a temporary workaround, pin the version with 'pip install transformers==4.49.0'.

pip install transformers==4.49.0
