It seems that langchain is incompatible with gptcache 
@hueiyuan can you show me a full demo code about this case?
This error seems to be caused by an incompatibility issue between langchain and gptcache. You can try using an older version of langchain.
This seems to need to be fixed in [langchain repo](https://github.com/langchain-ai/langchain)
