这个错误只要把OpenCV版本切换到4.2即可解决，但是又遇到了新问题如下，猜想会不会是因为torch的版本问题，我想将torch版本切换到1.6可是，提示我不能切换。

如果不是用gpu的话，而且这些库装的全是最新版的话，只要改两个地方，一个是self.inplace删掉，一个是把OpenCV-Python的版本改为4.2，完成这两个就能使用cpu执行detect.py了。作者的只能识别航拍中的船，

其余的应该要自己训练，
如果想使用gpu，我猜，不同于在YOLOv5.v5中，只要安装适合自己电脑的cuda和cudnn，再安装pytorch框架即可，而要安装作者指定的版本。

非常感谢您的解决方案，关于opencv的问题，只需要把getRotationMatrix2D参数改为int就可以了，就像作者说的后面的opencv可能不支持double
