迁移到 OpenAI Python API 库 1.x

  • 项目

OpenAI 刚刚发布了新版本的 OpenAI Python API 库。 本指南是对 OpenAI 迁移指南的补充，可帮助加快特定于 Azure OpenAI 的更改速度。

更新

  • 这是 OpenAI Python API 库的新版本。
  • 从 2023 年 11 月 6 日开始，pip install openai 和 pip install openai --upgrade 将安装 OpenAI Python 库 version 1.x。
  • 从 version 0.28.1 升级到 version 1.x 是一项中断性变更，需要测试和更新代码。
  • 出现错误时自动重试并回退
  • 正确的类型（适用于 mypy/pyright/editors）
  • 现在可以实例化客户端，而不是使用全局默认值。
  • 切换到显式客户端实例化
  • 名称更改

已知问题

迁移前进行测试

重要

Azure OpenAI 不支持使用 openai migrate 自动迁移代码。

由于这是具有中断性变更的库新版本，因此在迁移任何生产应用程序以依赖于版本 1.x 之前，应针对新版本广泛测试代码。 还应查看代码和内部流程，确保遵循最佳做法，并将生产代码固定到已完全测试的版本。

为了简化迁移过程，我们将 Python 文档中的现有代码示例更新为选项卡式体验：

pip install openai --upgrade

这提供了更改内容的上下文，并允许你并行测试新库，同时继续为版本 0.28.1 提供支持。 如果升级到 1.x 并意识到需要暂时恢复到以前的版本，则可以始终使用 pip uninstall openai，然后使用 pip install openai==0.28.1 重新安装到目标 0.28.1。

聊天完成

需要将变量 model 设置为部署 GPT-3.5-Turbo 或 GPT-4 模型时选择的部署名称。 输入模型名称将会导致错误，除非所选部署名称与基础模型名称相同。

import os
from openai import AzureOpenAI

client = AzureOpenAI(
  azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT"), 
  api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
  api_version="2024-02-01"
)

response = client.chat.completions.create(
    model="gpt-35-turbo", # model = "deployment_name".
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Does Azure OpenAI support customer managed keys?"},
        {"role": "assistant", "content": "Yes, customer managed keys are supported by Azure OpenAI."},
        {"role": "user", "content": "Do other Azure AI services support this too?"}
    ]
)

print(response.choices[0].message.content)

可以在我们的深入聊天补全文章中找到其他示例。

完成

import os
from openai import AzureOpenAI
    
client = AzureOpenAI(
    api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
    api_version="2024-02-01",
    azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
)
    
deployment_name='REPLACE_WITH_YOUR_DEPLOYMENT_NAME' #This will correspond to the custom name you chose for your deployment when you deployed a model. 
    
# Send a completion call to generate an answer
print('Sending a test completion job')
start_phrase = 'Write a tagline for an ice cream shop. '
response = client.completions.create(model=deployment_name, prompt=start_phrase, max_tokens=10)
print(response.choices[0].text)

嵌入

import os
from openai import AzureOpenAI

client = AzureOpenAI(
  api_key = os.getenv("AZURE_OPENAI_API_KEY"),  
  api_version = "2024-02-01",
  azure_endpoint =os.getenv("AZURE_OPENAI_ENDPOINT") 
)

response = client.embeddings.create(
    input = "Your text string goes here",
    model= "text-embedding-ada-002"  # model = "deployment_name".
)

print(response.model_dump_json(indent=2))

可以在我们的嵌入教程中找到其他示例，包括如何处理没有 embeddings_utils.py 的语义文本搜索。

异步

OpenAI 不支持在模块级客户端中调用异步方法，而是应实例化异步客户端。

import os
import asyncio
from openai import AsyncAzureOpenAI

async def main():
    client = AsyncAzureOpenAI(  
      api_key = os.getenv("AZURE_OPENAI_API_KEY"),  
      api_version = "2024-02-01",
      azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
    )
    response = await client.chat.completions.create(model="gpt-35-turbo", messages=[{"role": "user", "content": "Hello world"}])

    print(response.model_dump_json(indent=2))

asyncio.run(main())

身份验证

from azure.identity import DefaultAzureCredential, get_bearer_token_provider
from openai import AzureOpenAI

token_provider = get_bearer_token_provider(DefaultAzureCredential(), "https://cognitiveservices.azure.com/.default")

api_version = "2024-02-01"
endpoint = "https://my-resource.openai.azure.com"

client = AzureOpenAI(
    api_version=api_version,
    azure_endpoint=endpoint,
    azure_ad_token_provider=token_provider,
)

completion = client.chat.completions.create(
    model="deployment-name",  # gpt-35-instant
    messages=[
        {
            "role": "user",
            "content": "How do I output all files in a directory using Python?",
        },
    ],
)
print(completion.model_dump_json(indent=2))

使用数据

deployment = os.environ.get("AZURE_OPEN_AI_DEPLOYMENT_ID")

client = openai.AzureOpenAI(
    base_url=f"{endpoint}/openai/deployments/{deployment}/extensions",
    api_key=api_key,
    api_version="2023-08-01-preview",
)

completion = client.chat.completions.create(
    model=deployment,
    messages=[
        {
            "role": "user",
            "content": "How is Azure machine learning different than Azure OpenAI?",
        },
    ],
    extra_body={
        "dataSources": [
            {
                "type": "AzureCognitiveSearch",
                "parameters": {
                    "endpoint": os.environ["AZURE_AI_SEARCH_ENDPOINT"],
                    "key": os.environ["AZURE_AI_SEARCH_API_KEY"],
                    "indexName": os.environ["AZURE_AI_SEARCH_INDEX"]
                }
            }
