你好，这是我关于堆栈溢出的第一个问题。。。
我已经编写了Python脚本，它使用了最新的Python 3.7和最新的请求模块。我的请求查询是有效的，但是在一天内发出多个(数千个(请求之后，我有时会得到这个堆栈跟踪和程序退出。这是一个大的堆栈痕迹，我不确定我应该先调查哪些部分。如有任何帮助，将不胜感激
这是堆栈跟踪：

我已经通过这些网站回答了我自己的问题：https://www.peterbe.com/plog/best-practice-with-retries-with-requestshttps://realpython.com/python-requests/
它解释了如何使用传输适配器和智能回退。我目前每秒测试一次查询，该程序已经运行了24小时，没有问题。
