Looks stupid!
直接用Python就可以装Opencv3.3.0版本的。

sudo pip3 install opencv-contrib-python -i https://pypi.tuna.tsinghua.edu.cn/simple

还贼快！

具体可以参看https://medium.com/@debugvn/installing-opencv-3-3-0-on-ubuntu-16-04-lts-7db376f93961这个地方如何完整编译。

上述的方法导致cv2.VideoCapture()不好用。最好的方法还是自己编译一遍，，，详见https://github.com/BVLC/caffe/wiki/OpenCV-3.3-Installation-Guide-on-Ubuntu-16.04
