error: (-215:Assertion failed) !ssize.empty() in function ‘resize‘

有报错：
cv2.error: OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor’

1.问题原因：

(1)图片路径正确，且不含中文，但是图片路径不是全路径
(2)图片路径不对，没有找到图片
(3)图片路径中含有中文，函数报错

2.解决方案：
逐步检查
(1)文件路径是否正确
(2)是否是绝对路径(全路径)
(3)文件名中是否含有中文
(4)全路径中为\\或/

如果还没有办法解决，更详细的步骤参考!empty() in function ‘cv::CascadeClassifier‘
错误不同，但解决方法类似。
