问题背景以及问题描述：

在debug 过程中，出现了 Connection to Python debugger failed Socket closed 错误具体报错为：

Traceback (most recent call last):

NameError: name '_C' is not defined

Process finished with exit code 1

因此下意识我想run它（省略写）依然有错误，那么先解决 run 的问题：

LOGGER = logging.getLogger("concurrent.futures")
AttributeError: partially initialized module 'logging' has no attribute 'getLogger' (most likely due to a circular import)

Process finished with exit code 1

解决过程及问题成因：

看到问题的核心是(most likely due to a circular import) 即为一个循环的引用

那么大概率就是logging 这个模块有循环引用

果然文件同路径下有 logging.py 并且在 logging.py 中还 import 了 logging，造成了循环引用

解决方案：

更改名字避免循环引用：

connection to python debugger failed socket closed,python,开发语言

把原logging.py 更名为logging1.py

即可解决问题

结论及重点：

造成 Connection to Python debugger failed Socket closed 的原因会有很多，需要具体去看错误，循序渐进即可解决，在本例（most likely due to a circular import）中造成该情况的原因则是循环引用文章来源地址https://www.toymoban.com/news/detail-772921.html
