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_key=os.getenv("DASHSCOPE_API_KEY"), base_url="https://dashscope.aliyuncs.com/compatible-mode/v1", model="qwen3.7-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(content=human_text)] # 聊天模型支持多个消息作为输入 # messages = [SystemMessage(content=system_text), HumanMessage(content=human_text)] res = chat_model.invoke(messages) print(res)

2、运行报错，截图如下：

3、查看了版本后

请教大佬，大佬说这块更新换代了，要换成如下代码：

# 使用千问提供的模型调用模块 需下载模块 uv add langchain-qwq from dotenv import load_dotenv import os # 加载环境变量 load_dotenv() from langchain_qwq import ChatQwen llm = ChatQwen( model="qwen3.6-plus", api_key=os.getenv("DASHSCOPE_API_KEY"), base_url=os.getenv("DASHSCOPE_BASE_URL"), max_tokens=3000, ) result = llm.invoke("请介绍一下你自己！") print(result.content)

先安装依赖：

pip install langchain_qwq

然后执行成功:
