It seems that the version of langchain is incorrect causing the function cannot found. Could provide more detailed error information like library version, tools you used, questions you asked.

这个问题后面有解决么，我这边使用的langchain版本是0.0.193，使用的是单个tool问答，也碰到了
类似File "E:\workspace_shgl\BMTools-main\bmtools\agent\executor.py", line 99, in call
self.callback_manager.on_chain_start(
AttributeError: 'Executor' object has no attribute 'callback_manager'的问题
