Installing OpenCV for Python on Ubuntu, getting ImportError: No module named cv2.cv

Question

I have an Ubuntu 14.04 system, on which I want to install OpenCV and use it with Python 2.x.

I installed OpenCV using the instructions here: https://help.ubuntu.com/

Answer 1

Its complete installation nightmare, but I'll give one more hope you can avoid building opencv from source:

pip install opencv-contrib-python

Answer 2

For those who are trying to use 3.1.0 but after installing python says "cv2 module not found".

You likely have python but not python-dev.

sudo apt-get install python-dev

then reinstall 3.1.0 and it'll work.

Answer 3

if you are using pycharm platform it's very simple go into view=>tool windows==>python console after that you will see in the bottom the console with [1] : type this !pip install opencv-python

Answer 4

I also had this issue. Tried different things. But finally

conda install opencv

worked for me.

Answer 5

I think you don't have the python-opencv package.

I had the exact same problem and

sudo apt-get install python-opencv

solved the issue for me.

you can install opencv from the following link https://www.learnopencv.com/install-opencv3-on-ubuntu/ It works for me . apt-get install doesnt contain many packages of opencv

Answer 6

Find where the cv2.so is, for example /usr/local/lib/python2.7/dist-packages, then add this into your ~/.bashrc by doing:

sudo gedit ~/.bashrc

and add

export PYTHONPATH=/usr/local/lib/python2.7/dist-packages:$PYTHONPATH

In the last line

And then remember to open another terminal, this can be work, and I have solve my problem. Hope it can help you.
