How to install OpenCV for python3 in Ubuntu?

0 votes

I want to install OpenCV for python3 in ubuntu 16.04. Fist I tried running sudo apt-get install python3-opencv which is how I pretty much install all of my python software. This could not find a repository. 

The install does work however if I do sudo apt-get install python-opencv this issue with this is that by not adding the three to python it installs for python 2 which I do not use. I would really perfer not to have to build and install from source so is there a way I can get a repository?

 I also tried installing it with pip3 and it could not find it either.

I found this:

https://pypi.python.org/pypi/opencv-python

OpenCV on wheels

'Unofficial OpenCV packages for Python.'

Installation was painless for Ubuntu 16.04

pip3 install opencv-python

Check the installation

python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'3.2.0'

Not sure why this wasn't mentioned. Perhaps it is newly available?
