我尝试使用langchain openai，但始终无法使其正常工作。
我尝试了openai的快速开始测试：
from openai import OpenAIclient = OpenAI()completion = client.chat.completions.create( model="gpt-3.5-turbo", messages=[ {"role": "system", "content": "You are a poetic assistant, skilled in explaining complex programming concepts with creative flair."}, {"role": "user", "content": "Compose a poem that explains the concept of recursion in programming."} ])print(completion.choices[0].message)但它会报错：
line 98, in __init__ raise OpenAIError(openai.OpenAIError: The api_key client option must be set either by passing api_key to the client or by setting the OPENAI_API_KEY environment variable但在这样设置API密钥后：
import openaiimport osos.environ["OPENAI_API_KEY"] = "myapikey"client = openai.OpenAI()completion = client.chat.completions.create( model="gpt-3.5-turbo", messages=[ {"role": "system", "content": "You are a poetic assistant, skilled in explaining complex programming concepts with creative flair."}, {"role": "user", "content": "Compose a poem that explains the concept of recursion in programming."} ])print(completion.choices[0].messages)它会显示一大堆错误信息：

首先，您需要在项目文件夹中创建一个“.env”文件，像这样
# Once you add your API key below, make sure to not share it with anyone! The API key should remain private.OPENAI_API_KEY=abc123然后在代码初始化时，它会默认读取该环境变量：
from openai import OpenAI
client = OpenAI()# defaults to getting the key using os.environ.get("OPENAI_API_KEY")# if you saved the key under a different environment variable name, you can do something like:# client = OpenAI(# api_key=os.environ.get("CUSTOM_ENV_NAME"),# )还要确保您已正确安装库。或者，您可以直接传递API密钥，但这不推荐，因为这样会暴露在代码中。
!pip install --upgrade pipfrom openai import OpenAIclient = OpenAI(api_key='yourapikey')completion = client.chat.completions.create( model="gpt-3.5-turbo", messages=[ {"role": "system", "content": "You are a poetic assistant, skilled in explaining complex programming concepts with creative flair."}, {"role": "user", "content": "Compose a poem that explains the concept of recursion in programming."} ])print(completion.choices[0].message)在您发布错误日志后，我终于明白了。错误信息显示您的账户没有余额。您需要一个有效的密钥，或者在您的账户上购买额度。请在这里检查您的账户使用情况 这里。
