解决了使用langchain调用聊天模型报的错

1、代码如下#!/usr/bin/env python # -*- coding: UTF-8 -*- from langchain_community.chat_models import ChatTongyi from langchain_core.messages import HumanMessage, SystemMessage from dotenv import load_dotenv import os load_dotenv() human_text 你好啊 system_text 你是一个强大的助手你的名字叫0713 # 聊天模型 chat_model ChatTongyi( api_keyos.getenv(DASHSCOPE_API_KEY), base_urlhttps://dashscope.aliyuncs.com/compatible-mode/v1, modelqwen3.7-plus, # 此处以qwen-plus为例您可按需更换模型名称。模型列表https://help.aliyun.com/zh/model-studio/getting-started/models ) messages [HumanMessage(contenthuman_text)] # 聊天模型支持多个消息作为输入 # messages [SystemMessage(contentsystem_text), HumanMessage(contenthuman_text)] res chat_model.invoke(messages) print(res)2、运行报错截图如下报错内容如下C:\Users\lenovo\PycharmProjects\PythonProject\.venv\Scripts\python.exe C:\Users\lenovo\PycharmProjects\PythonProject\rag\day03\10-聊天模型.py C:\Users\lenovo\PycharmProjects\PythonProject\rag\day03\10-聊天模型.py:5: DeprecationWarning: langchain-community is being sunset and is no longer actively maintained.
