解决python测试opencv时imread导致的错误问题

如下所示：

import cv2
import 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.py
OpenCV Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file C:buildmaster_winpack-bindings-win64-vc14-staticopencvmoduleshighguisrcwindow.cpp, line 325
Traceback (most recent call last):
