由于您使用的是python3的较新版本，您可能必须自己根据配方来构建opencv，可从https://github.com/conda- forge/opencv-Feedstock获得
另一个选择是通过像这样创建新版本的特定环境中的python3：
(root) osx:Downloads nwani$ conda list | grep python
python 3.6.0 0
(root) osx:Downloads nwani$ conda create -yn opencvtest python=3.5.2
(root) osx:Downloads nwani$ source activate opencvtest
(opencvtest) osx:Downloads nwani$ conda list | grep python
python 3.5.2 0
该conda-forge通道上提供了opencv的3.1.0版本版本：
(root) osx:Downloads nwani$ conda search -c conda-forge --spec 'opencv=3*'

(opencvtest) osx:Downloads nwani$ conda list | grep -e python -e opencv
