IndexError: index 0 is out of range

[Louis24]

首先谢谢您的教程，我最近在看网络裁剪，然后找到了这 https://blog.csdn.net/m0_53608998/article/details/117687416

在运行时发现少了很多文件，我就从

repo

https://github.com/ZJU-lishuang/yolov5_prune

缺省文件从下面找

https://github.com/ZJU-lishuang/yolov5-v4 https://github.com/ultralytics/yolov5

然后我直接裁剪发现 IndexError: index 0 is out of range

我重新训练的时候也是报错，请问是什么问题呢

网络结构没对上，旧版本只支持yolov5s模型
