[Fix] limiting the maximum version of transformers avoids null pointer

[Kit-Hung]

After transformers version 4.41.0, the method of obtaining the sample model cache_position was changed to cause a null pointer during finetune, limiting the maximum version of transformers avoids this problem.

@Kit-Hung How can this issue be reproduced? Perhaps there are other ways that could be compatible with 4.41.0?
