6 代码演示

安装依赖

pip install openaipip show openai

导入依赖

from openai import OpenAI
import openai
import os

初始化客户端

openai.api_key = os.getenv("OPENAI_API_KEY")client = OpenAI(api_key=openai.api_key)

执行代码

print(client.models.list())

• 可以看到，支持的模型有：

遇到的问题

问题一：ConnectTimeout

• 找到你的翻墙工具的本地代理端口地址进行设置

export http_proxy=http://127.0.0.1:9910
export https_proxy=http://127.0.0.1:9910

问题二：RateLimitError: Error code: 429 - {‘error’: {‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.’, ‘type’: ‘insufficient_quota’, ‘param’: None, ‘code’: ‘insufficient_quota’}}

• 被限额度，按理说新注册用户默认是有 5 美元的，每天也有一定量的token使用量才对，尝试了好久还是没能解决。最终决定充点钱试一试~~
• Add payment method 需要添加海外的银行卡或信用卡，如果没有的话，可以申请一张虚拟卡，推荐使用WildCard进行申请，虚拟卡地址：https://bewildcard.com/i/FCDWVYHJ
  • 需要注册账户，并开通会员，申请虚拟卡最低是2年，需要支付10.99美元
  • 申请好虚拟卡后，就可以填写银行卡信息，成为 OpenAI 的付费用户了
• 成为付费用户后，各种限制就都扩大了，能使用的模型更多，token量以及速率都会提升。

• 解除限制后，再进行OpenAI的API调用就非常顺利了。
