按照您的步骤训练报了错误。我之前用您的代码训练1080p的图片是完全可以的，现在我训练1280*960的图片就报这个错误了

cv2.error: OpenCV(4.5.3) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-q3d_8t8e\opencv\modules\core\src\copy.cpp:1026: error: (-215:Assertion failed) top >= 0 && bottom >= 0 && left >= 0 && right >= 0 && _src.dims() <= 2 in function 'cv::copyMakeBorder'

有以下原因参您参考：

【1】 有时候Yolo算法检测出来的检测框坐标偶尔会在边界出现负数错误，比如[-1,234,54,5]，那么你需要输出坐标查到底是哪一个坐标出现问题，并且在出现负数错误的时候检测出来把负数变零

【2】 也可能是没有检测出目标 From JintuZheng
