task = asyncio.create_task(wrap_done( chain.acall({"context": context, "question": query}), callback.done), )添加历史信息参数

[sevenandseven]

你好，我想请问下，我在prompt里添加了chat_history变量， 然后在： task = asyncio.create_task(wrap_done( chain.acall({"context": context, "question": query，“chat_history”:history}), callback.done), ) 里边也添加了chat_hostory参数，但是他为什么报错，说是输入变量只能有一个。

提示模板是：chat_prompt = PromptTemplate(template=prompt_template, input_variables=["question", "context", "chat_history"])

请问是哪里需要修改？

It seems like the issue you're encountering with the chain.acall method and the chat_history parameter is due to how chain.acall is designed to accept its arguments. Typically, chain.acall expects a dictionary with specific keys, and based on your description, it looks like it's expecting a single input, possibly under a key like "input".

If chain.acall is not designed to accept a "chat_history" parameter directly, adding it as you did would indeed cause an error. The method's expected parameters need to align with how you're calling it. Since you've added "chat_history" to your PromptTemplate as an input variable, you'll need to ensure that chain.acall or any method it delegates to is capable of handling this additional parameter.

To resolve this, you should:

1. Verify the expected parameters of chain.acall and adjust your call accordingly. If chain.acall is designed to work with a specific structure, your dictionary keys and values must match this expectation.
2. If chain.acall cannot be modified to accept "chat_history", consider how this data can be incorporated into the existing parameters in a way that the method can process.

Without more details on the error message or the implementation of chain.acall, this is a general direction to investigate. Ensuring that the parameters you pass match the method's expectations is key to resolving the issue.
