chatgpt之api的调用问题

1.调用api过程中，出现如下报错内容

先写一个测试样例

import openai


openai.api_key = "OPEN_AI_KEY"
openai.api_base="OPEN_AI_BASE_URL" # 是否需要base根据自己所在地区和key情况进行

completion = openai.ChatCompletion.create(
    model="gpt-3.5-turbo",
    messages=[
        {
            "role": "user",
            "content": "帮我用python写topk算法"
        },
    ]
)

print(completion.choices[0].message)

运行后，出现如下报错。

You tried to access openai.ChatCompletion, but this is no longer supported in openai>=1.0.0 - see the README at https://github.com/openai/openai-python for the API.

You can run `openai migrate` to automatically upgrade your codebase to use the 1.0.0 interface.

Alternatively, you can pin your installation to the old version, e.g. `pip install openai==0.28`

A detailed migration guide is available here: https://github.com/openai/openai-python/discussions/742

2. 解决问题

根据提示可知道，是API更新的缘故，查阅文档对代码进行修改即可。

import openai


openai.api_key = "OPEN_AI_KEY"
openai.api_base="OPEN_AI_BASE_URL" # 是否需要base根据自己所在地区和key情况进行

# 区别主要是将openai.ChatCompletion.create换成openai.chat.completions.create
completion = openai.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[
        {
            "role": "user",
            "content": "帮我用python写topk算法"
        },
    ],
)
print(completion.choices[0].message.content)

正常运行即可，结果如下：

3.思考

api_base是干嘛的？其实他就是调用api过程中的镜像网站，避免连接不上或者被block。
