langchain的sdk也升级了

前两天升级openai后，这两天一直在解决下面的错误，openai的error属性缺失

File /usr/local/lib/python3.11/site-packages/langchain/chat_models/openai.py:77, in _create_retry_decorator(llm, run_manager)
     68 def _create_retry_decorator(
     69     llm: ChatOpenAI,
     70     run_manager: Optional[
     71         Union[AsyncCallbackManagerForLLMRun, CallbackManagerForLLMRun]
     72     ] = None,
     73 ) -> Callable[[Any], Any]:
     74     import openai
     76     errors = [
---> 77         openai.error.Timeout,
     78         openai.error.APIError,
     79         openai.error.APIConnectionError,
     80         openai.error.RateLimitError,
     81         openai.error.ServiceUnavailableError,
     82     ]
     83     return create_base_retry_decorator(
     84         error_types=errors, max_retries=llm.max_retries, run_manager=run_manager
     85     )

AttributeError: module 'openai' has no attribute 'error'

开始有点着急，毕竟openai已经是最新版本了，不想降级，然后就开始把openai.py里的相关code都注释掉，这下可好，压下葫芦起了瓢，各种稀奇古怪的问题都跑出来，
不得已检查各种包的版本

pip3 list --outdated

发现langchain也要升级了，最后一招制敌。

pip3 install --upgrade langchain

升级到新版本后，问题解决了

pip3 show langchain       
Name: langchain
Version: 0.0.352

如果按照网上的建议，非得降级才能解决，这不是自断手脚嘛。

pip install openai==0.28.1
pip install langchain==0.0.330
