When does this happen?
IF When using transformers version 4.50.0, a RuntimeError occurs: 'register_pytree_node() got an unexpected keyword argument flatten_with_keys_fn'.
How others solved it
THEN Downgrade transformers to version 4.49.0 to avoid this compatibility issue. Pin the version in your environment or requirements file (e.g., using `pip install transformers==4.49.0`). This resolves the error on Linux and Windows.
pip install transformers==4.49.0
