解决方案

Install OpenCV

Refresh the packages index and install the OpenCV package by typing:

sudo apt update

sudo apt install python3-opencv

The command above will install all packages necessary to run OpenCV.

Verify the OpenCV installation

To verify the installation we will import the cv2 module and print the OpenCV version:

>>> import cv2

>>> cv2.__version__

Output

3.2.0
