Edit:

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

pip3 install opencv-python

Read the rest of the comments for other solutions if that doesn't work.

Original comment:

Could you try the solution in the last part of this comment?

[bendandersen]

The conda command is not found. Did I install something wrong?

Could you try sudo apt install libopencv-dev python-opencv?

[bendandersen]

When I run that line in the terminal it returns with already having the
newest version. So I don’t think that’s it.

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

[stellarpower]

That worked for me.

[missxa]

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

https://github.com/boltgolt/howdy/issues/32#issuecomment-386876427 work for me

[davidgaya]

pip3 install opencv-python worked for me

[boltgolt]

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

[cccaballero]

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

[boltgolt]

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.

[boltgolt]

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.

[VanVan]

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
