404エラーをトラブルシュートする男性

OpenAI APIライブラリのエラー

response = client.chat.completions.create(
 model="text-davinci-001",
 messages=[
   {
    "role": "user", 
    "content": "List two data science professions with related skills in json format."
   }
 ],
 response_format={"type": "json_object"}
)

NotFoundError: Error code: 404 - {'error': {'message': 'The model `text-davinci-001` 
has been deprecated, learn more here: https://platform.openai.com/docs/deprecations'}}

接続エラー

一般に、ユーザー側またはサービス側の接続問題が原因

例: InternalServerError, APIConnectionError, APITimeoutError

対処案:
- 接続設定を確認
- 解決しなければサポートに連絡

リソース上限制限エラー

一般に、リクエスト頻度やテキスト量の上限が原因

例: ConflictError, RateLimitError

対処案:
- 上限制約を確認
- リクエストが上限内か確認

response = client.chat.completions.create(

    response = client.chat.completions.create(
     model="gpt-4o-mini",
     messages=[{"role": "user", 
      "content": "List five data science professions."}])

  pass
