RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory问题解决

环境：Windows10，yolov5-5.0，Anaconda3的python3.8虚拟环境

以下是具体报错

(yolov5_p3.8) C:\ProgramData\yolov5_distillation-5.0>python detect.py

也算是个纯小白，基本上啥也不懂，问了大佬说是Namespace后面括号里的weights默认值需要改一下。但是代码还没去研究，所以可以先自己设置参数。

python detect.py --weights weights/yolov5s.pt

成功！
