AuthenticationError:OpenAPI api中的<空消息>

我一直在尝试使用langchain库的 ChatOpenAI ,I pip安装langchain,并导入 ChatOpenAI

我在colab上运行我的代码,所以我将openAI的api密钥设置为:

%env OPENAI_API_KEY= my_api_key

现在当我尝试初始化时 ChatOpenAI 如下所示,它运行时没有出现错误:

chat = ChatOpenAI(temperature=0.0,openai_organization='Personal')
chat

结果如下:

ChatOpenAI(verbose=False, callbacks=None, callback_manager=None, client=<class 'openai.api_resources.chat_completion.ChatCompletion'>, model_name='gpt-3.5-turbo', temperature=0.0, model_kwargs={}, openai_api_key='my_api_key', openai_api_base='', openai_organization='Personal', openai_proxy='', request_timeout=None, max_retries=6, streaming=False, n=1, max_tokens=None)

但当我尝试将其作为:

customer_response = chat(customer_messages)

它抛出以下错误:

---------------------------------------------------------------------------
