Hello, did you solve it? I meet the same problem.

Hi there,

Thanks for reporting this issue! The problem may be caused by incompatibility with the higher version of transformers.

You can try either of the following solutions:

• Use the updated uv environment.
• Downgrade the transformers version.

Let me know if this resolves your problem.

Hi @Twinkle-ce ,

I think this error is caused by this PR:
huggingface/transformers#36263

The best way to solve this error is to use the same version of transformers as in the README.

Thanks for pointing out this.
