如下所示：

import cv2import numpy as np img = cv2.imread("1.jpg")//图片和代码在同个目录，改为相对路径，解决由imread引起的打不开图片或找不到图片的路径问题cv2.imshow("1",img)cv2.waitKey(10000)D:\>my.pyOpenCV Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file C:\build\master_winpack-bindings-win64-vc14-static\opencv\modules\highgui\src\window.cpp, line 325Traceback (most recent call last): File "D:\my.py", line 5, in <module> cv2.imshow("1",img)cv2.error: C:\build\master_winpack-bindings-win64-vc14-static\opencv\modules\highgui\src\window.cpp:325: error: (-215) size.width>0 && size.height>0 in function cv::imshowD:\>
