Hi @isAXuan, thanks for your feedback.

It looks like the local model issue. Could you try to set model_name=microsoft/llmlingua-2-xlm-roberta-large-meetingbank for now?

Thank you very much for your reply. My problem has been solved. I checked my environment and it should be caused by the naming of the local model weight file.

@jiapingW 你好，我也遇到了相同的问题，跟命名有什么关系呢？请问下你最后是怎么解决的呢？

rename the local dir where you download the model from hf to include "xlm-roberta-large" in dir name
