问题描述

今天在敲代码的时候遇到了一个问题，报错信息如下所示：

File "D:\Python_Study\Github_Repositories\Hotspot-Detector\algorithm\net\ssd.py", line 7, in <module>
import torch
File "D:\Python\lib\site-packages\torch\__init__.py", line 29, in <module>

raise ImportError(
ImportError: The 'pyparsing' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution

这就很让人纳闷，上一秒同一个文件还跑的好好的，下一秒怎么就跑不起来了？更奇怪的是，连 VS Code 的格式化文件功能都不起作用了。

问题解决

又仔细看了一下自己的文件夹，发现刚才偷懒新建了一个

copy.py
