    QuestionQuestion

    I am trying to opencv i.e cv2 on my Linux server which has following configurations.

    Linux D07-CPT-8gb-4cpu-nyc1 4.4.0-92-generic #115-Ubuntu SMP Thu Aug
    10 09:04:33 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    Before trying on the server I tried this command on my Bash for Windows and working fine here.

    sudo apt-get install libopencv-dev python-opencv
    

    I ran the same command on Linux server but when I type import cv2 I am getting this error.

    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ImportError: No module named 'cv2'
    

    opencvis not listed when I check with pip freeze.
    Note: I am using python 3.5.2

    At least on Ubuntu 16.04, there exist Python 2 and Python 3.

    So when install package for python, you should be care of your python version. The default python and pip is for Python 2.

    Solutions:

    1. specific the Python version

    sudo python3 -m pip install opencv-python 
    

    2. install python3-pip, and then use python3 and pip3

    sudo apt install python3-pip
    pip3 install opencv-python
