ImportError: no module named 'cv2' Python3

Question

I have such a problem

(face_det) user@pc:~$ python3
Python 3.5.3 (default, Apr 22 2017, 00:00:00) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'cv2

I don't have it on python2:

(face_det) user@pc:~$ python2
Python 2.7.13 |Anaconda custom (64-bit)| (default, Dec 20 2016, 23:09:15)

Despite the fact that I have opencv (I also tried uninstalling it and installing it later):

(face_det) user@pc:~$ pip3 install opencv
Requirement already satisfied: opencv in ./.virtualenvs/face_det/lib/python3.5/site-packages
(face_det) user@pc:~$ conda install opencv

Answer 1

Try

pip3 install opencv-python

to get cv2. I'm not sure when it opencv-pythonbecame available. I built opencv manually, but when I looked a few weeks ago, it was like that. I use cv2with Python3 in a VM that works ubuntu/trusty64.

Answer 2

I think you're on Linux, judging by pc:~$

Try setting the following link:
