译文：执行请求失败：上游错误：执行请求失败

2. 原因分析

3.解决方案

import requests
from tenacity import retry, stop_after_attempt, wait_exponential

# 重试装饰器：最多3次，指数退避（2→4→8秒）
@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=2, max=10))
def call_dmx_model(api_url, payload):
    resp = requests.post(api_url, json=payload, timeout=10)
    resp.raise_for_status()  # 抛出HTTP 4xx/5xx错误
    return resp.json()

# 使用示例
try:
    result = call_dmx_model(
        api_url="https://api.dmxapi.com/v1/model",  # 替换为实际端点
        payload={"model": "your-model-id", "prompt": "test"}
    )
    print("请求成功:", result)
except Exception as e:
    print(f"最终失败（已重试）: {str(e)}")
