Installing opencv for python3

Question

Has anyone tried to install opencv for python3?. As stated here http://opencv.willowgarage.com/wiki/InstallGuide its support status is unknown. So I want to try it:

Answer 1

I got the thing to at least build and install. It can load the cv2 module just fine. Haven't tested too much though.

Answer 2

Use the pip application.

On ubuntu:

sudo apt install python3-pip

and so, on command line:

pip3 install --upgrade pip

pip3 install opencv-python

Answer 3

At the moment OpenCV supports Python 2.x only. OpenCV (including OpenCV 2.4) does not compiles with Python 3.x.

Python3 support is already in wishlist for future versions of OpenCV. But currently there are no activities in this direction and you are welcome to create and contribute a patch resolving the compatibility issues.
