经常跟图像打交道的程序员对cv2这个函数不会陌生。今天我就讲讲如何在anaconda上安装opencv库。

首先要知道使用cv2函数必须安装opencv库,cv2只是opencv里的一个小部分库函数。

安装opencv库有三种方法。

一  用anaconda自带的navigator安装

此种方法比较简单,但是安装等待的时间比较长。

参考百度经验的帖子:https://jingyan.baidu.com/article/fdbd4277bf0816b89e3f4807.html

二 用anaconda prompt上安装

参考CSDN的博客帖子:ttps://blog.csdn.net/weixin_39278265/article/details/83216500

三 用cmd命令窗口上安装

参考CSDN的博客帖子:https://blog.csdn.net/iracer/article/details/80498732

本人试了第一种和第三种方法,觉得第一种比较耗时,第三种比较快速。

所以推荐第三种方式。
