HumanInputLLM とともに、LangChain はまたテスト、デバッグや教育目的で使用できる擬似 Chat Model クラスを提供します。これは Chat Model への呼び出しを模倣して人間がメッセージを受け取ったときにどのような応答をするのかシミュレートすることを可能にします。

このノートブックでは、これの使用方法を調べます。

エージェントで HumanInputChatModel を使用することからこれを始めます。

from langchain.chat_models.human import HumanInputChatModel

API リファレンス :

• HumanInputChatModel

このノートブックでは WikipediaQueryRun ツールを使用しますので、wikipedia パッケージをまだインストールしてないのであればその必要があるかもしれません。

%pip install wikipedia

tools = load_tools(["wikipedia"])
llm = HumanInputChatModel()

agent = initialize_agent(
    tools, llm, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
