调用OpenAI API时出现POST /v1/fine-tunes请求URL未知错误求助

运行以下代码时触发错误：Unknown request URL: POST /v1/fine-tunes

代码示例：

import openai
import os
from dotenv import load_dotenv

load_dotenv()

openai.api_key = os.getenv('API_KEY')

def upload_file(file_path):
    try:
        response = openai.File.create(
            file=open(file_path, "rb"),
            purpose="fine-tune"
        )
        print("File uploaded successfully.")
        print(response)
        return response['id']
    except Exception as e:
        print(f"Error uploading file: {e}")
        return None

def create_fine_tune_task(file_id, model_name):
    try:
        response = openai.FineTune.create(
            training_file=file_id,
            model=model_name
        )
        print("Fine-tune job created successfully.")
        print(response)
    except Exception as e:
        print(f"Error creating fine-tune job: {e}")


file_path = "output/8ec61610f6a5652f31a664153c20803639747017.jsonl"
model_name = "gpt-3.5-turbo"

file_id = upload_file(file_path)
if file_id:
    create_fine_tune_task(file_id, model_name)

这个错误的核心原因是OpenAI Python SDK v1.0+版本已经废弃了旧的openai.FineTune接口，改用全新的微调任务API。具体修复步骤如下：

• 替换微调任务创建方法
  将代码中的openai.FineTune.create替换为openai.FineTuningJob.create，参数无需调整。

• 修复后的完整代码

import openai
import os
from dotenv import load_dotenv

load_dotenv()

openai.api_key = os.getenv('API_KEY')

def upload_file(file_path):
    try:
        response = openai.File.create(
            file=open(file_path, "rb"),
            purpose="fine-tune"
        )
        print("File uploaded successfully.")
        print(response)
        return response['id']
    except Exception as e:
        print(f"Error uploading file: {e}")
        return None

def create_fine_tune_task(file_id, model_name):
    try:
        response = openai.FineTuningJob.create(
            training_file=file_id,
            model=model_name
        )
        print("Fine-tune job created successfully.")
        print(response)
    except Exception as e:
        print(f"Error creating fine-tune job: {e}")


file_path = "output/8ec61610f6a5652f31a664153c20803639747017.jsonl"
model_name = "gpt-3.5-turbo"

file_id = upload_file(file_path)
if file_id:
    create_fine_tune_task(file_id, model_name)

• 升级SDK确保兼容性
  如果你的SDK版本低于v1.0，执行以下命令升级到最新版：

pip install --upgrade openai
