No module named 'cv2' about howdy HOT 14 CLOSED

was missing python3 bindings as well, fixed with pip3 install opencv-python

from howdy.

I have solved this issue in Ubuntu 18.04 installing the python3-opencv package:

sudo apt install python3-opencv

adding it as dependency for the .deb package can solve the issue in Ubuntu 18.04

from howdy.

Looks like you're only missing the python 3 bindings, could you try following 2, 2.1 and 2.2 of this tutorial?

pip3 install opencv-python worked for me

from howdy.

Thank you, it works now.
However I needed to install these package, it was not automatic

sudo pip3 install opencv-python
sudo apt install libopencv-dev python-opencv
sudo pip3 install dlib

from howdy.

Edit:

To install the python bindings for opencv, run the following command:

pip3 install opencv-python

#32 (comment) work for me

from howdy.

It also works as expected on the travis 16.04 instance, it seems very machine dependent

from howdy.

python-opencv fails to install on many 16.04 installations though, which breaks this package all together if it would be a dependency. I might add a catch for a missing OpenCV library with a link to a wiki page with further instructions.

This last release should now automatically detect this problem and fix it. Feel free to reopen this issue if you still have the same problem on version 2.4.0 or above.
