I have here is a combination of python to install and use openCV, after installation in order to use, but also the mainstream

第一步：下载python环境

下载地址：https://www.python.org/downloads/
下载之后安装，切记在第一步骤，勾选配置环境变量

第二步：安装依赖库
首先，进入python安装环境的scripts目录下，执行命令
方式：可以使用cmd，然后cd 到scripts目录
     或者安装git的，直接在scripts目录下右击git bash here

pip install wheel
pip install numpy
pip install opencv-python

第三步：测试环境
我是在pycharm上面写的代码，需要的可以下载安装一下pycharm

import cv2
import numpy as np
 
img = cv2.imread("1.jpg")
cv2.imshow("1",img)
cv2.waitKey(10000)


如果使用pycharm，引入包依赖的时候找不到，那么直接选择install xxx包即可
结果就是显示图片框
