openai.APIConnectionError: Connection error. 请问怎么解决呢？

Question

这是我学习langchain时，跟着学习视频运行的第一个代码
我的python版本是3.10.0
openai的密钥也添加在环境变量当中了
梯子是猫猫，挂在新加披或者日本的，能够正常访问openai页面
试了很多中办法都没用：

#引入langchain牌天场最的提示词模版
from langchain_core.prompts import ChatPromptTemplate
#引入langchain openai sdk
from langchain_openai import ChatOpenAI
llm = ChatOpenAI()


prompt = ChatPromptTemplate.from_messages([
    ("system","你是世界级的技术专家"),  #角色
    ("user","{input}") #用户提示词input
])
#通过langchain的链式调用，生成一个chain
#使用|将定义的llm ai大模型和提示词模板promt链接起来
chain =prompt | llm
result = chain.invoke({"input":"帮我写一篇关于AI的技术文章，100个字"})
print(result)

但是报错：

让阿豪来帮你解答，本回答参考chatgpt3.5编写提供，如果还有疑问可以评论或留言

根据您提供的代码和报错信息，您遇到了一个SSL连接问题。请您尝试以下解决方法：

1. 确保您的Python版本与OpenAI SDK兼容。您可以查看OpenAI官方文档或GitHub页面来确认兼容性。
2. 确保您的网络连接稳定并且没有被防火墙或代理服务器阻止。您可以尝试在不使用猫猫梯子的情况下运行代码，看看是否仍然出现相同的错误。
3. 检查您的OpenAI密钥是否正确并且已经添加到环境变量中。您可以再次确认密钥是否有效。
4. 尝试更新您的HTTP请求库（例如httpx）到最新版本，可能存在bug已经在最新版本中修复。 根据报错信息中提到的"EOF occurred in violation of protocol"，此错误通常涉及到SSL/TLS协议相关问题，可能是因为SSL连接时发生了异常导致的。尝试上述方法中的一种或多种解决方法，希望能帮助您解决问题。 如果问题仍然存在，请尝试在正常网络环境下运行代码，排除猫猫梯子可能引起的问题。如果仍然无法解决，请提供更多细节或尝试与OpenAI支持团队联系以获取帮助。
