ValueError: Received unsupported message type for Ollama

报错：

  File "/opt/miniconda/lib/python3.9/site-packages/langchain_community/chat_models/ollama.py", line 134, in _convert_messages_to_ollama_messages
    raise ValueError("Received unsupported message type for Ollama.")
ValueError: Received unsupported message type for Ollama.

 

修改一下调用ollama的方式就好啦 

from langchain_ollama import ChatOllama, OllamaEmbeddings

react_agent = create_react_agent(model=ChatOllama(model="qwen2.5:32b"), tools=tools, prompt=react_prompt)
