情况如上图,由于cv2包的替代包opencv-python较大,安装经常出现所示卡死情况,解决方案如下:

        ①更新pip版本:pip install --upgrade pip ,之后再次尝试
        ②由于一般要下载30min左右,有时会误认为是卡死,此时需要用--verbose 进行安装命令跟踪安装过程,可以在每一行最前端显示安装百分比:pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple --verbose ,之后耐心等待即可

        ③使用pip装是源码编译安装的,所说的Building wheel for opencv-python就是在编译,编译非常慢,想快一点的话就用apt来装python版本cv,那个是预编译过的。

 

 最终安装完成:

祝大家都能成功解决该问题,欢迎在评论区交流!
