出现错误，无法安装opencv-python==4.5.1.48

尝试加下载镜像无法解决

最终自行去官网下载安装包解决
官网链接
https://pypi.org/project/opencv-python/4.5.1.48/#files

cp39就是python3.9版本
以此类推
我下载的是opencv_python-4.5.1.48-cp36-cp36m-win_amd64.whl
因为电脑是64位，Windows，python3.6+
大家按照实际情况下载

然后 pip install opencv_python-4.5.1.48-cp36-cp36m-win_amd64.whl

报错找不到这个包
将包放进报错路劲C:\Users\Administrator\
再次运行安装

成功
检查包的情况 conda list

搞定！！！
