6.opencv 按装

pip install opencv-python
pip install opencv-contrib-python

pip uninstall opencv-python==4.5.4.58
pip uninstall opencv-python
pip uninstall opencv-contrib-python

import cv2不报错则成功

地址一定要对，不能出错

我用的纯数字，怎么改都报错，后面改了英文成功了，又偿试再次改回数字未报错

 切记地址用数字报错坑了我很长时间，尽量用英文名

# print('hello world')
import cv2
img = cv2.imread('D:\\823.jpg')
cv2.imshow('image',img)
cv2.waitKey(0)
