推荐答案
我在使用conda安装opencv时遇到了无数问题 这是我的方法，如果您还没有环境，请创建一个环境
I have had countless problems with installing opencv with conda This is my approach, create an env if you don't already have one
conda create -n py36 python=3.6
conda activate py36
使用pip 否 conda
pip install opencv-python
如果仍然有问题，请卸载opencv，更新ffmpeg
If your still having an issue, uninstall opencv, update ffmpeg
conda install -c conda-forge ffmpeg
然后重新运行pip
