Deprecation issue with the latest Transformers

[AbhilashPal]

Facing the following issue regarding AdamW being removed from transformers in version 4.50 onwards I believe. The last transformers version compatible with ragchecker is 4.49 at present. It would be great if the import can be fixed :

Issue : huggingface/transformers#36954

same problem

I had a same problem, and it was solved by re-installing dependency libraries.
The error was occurred in "refchecker" code, and it was updated recently.
Up-to-date "refchecker" solves the issue.
