OpenAI微调python返回null模型

我正在尝试使用python从OpenAI ChatGPT中获得微调模型，代码如下

#upload training data

upload_response = openai.File.create(
  file=open(file_name, "rb"),
  purpose='fine-tune'
)
file_id = upload_response.id
print(f'\nupload training data respond:\n\n {upload_response}')

OpenAI响应数据

 {
  "bytes": 380,
  "created_at": 1675789714,
  "filename": "file",
  "id": "file-lKSQushd8eABcfiBVwhxBMOJ",
  "object": "file",
  "purpose": "fine-tune",
  "status": "uploaded",
  "status_details": null
}

我的培训文件已上载，因此我正在检查代码的微调响应

fine_tune_response = openai.FineTune.create(training_file=file_id)
print(f'\nfine-tune respond:\n\n {fine_tune_response}')

我得到了

正如您所看到的，fine_tune_mode为空，因此我无法将其用于Completion
