使用langchain调用大语言模型报的错

1、代码如下图所示，希望大语言模型能帮我补全这段文本。

#!/usr/bin/env python
# -*- coding: UTF-8 -*-

from langchain_community.llms import Tongyi
from dotenv import load_dotenv
import os

load_dotenv()

# LLM纯文本补全模型
llm = Tongyi(api_key=os.getenv("DASHSCOPE_API_KEY"),
                 base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
                 model="qwen3.7-plus")

text = "我的真的好想（帮我补全这个文本）"
res = llm.invoke(text)
print(res)

2、执行代码，报错了，

报错内容如下：

Process finished with exit code 1

把model改成model_name就好了。

model参数只支持最原始的qwen-max\qwen-plus\
