nstallation and Usage

1. If you have previous/other version of OpenCV installed (e.g. cv2 module in the root of Python’s site-packages), remove it before installation to avoid conflicts.

• To further avoid conflicts and to make development easier, Python’s virtual environments are highly recommended for development purposes.

1. If you have an existing opencv-contrib-python installation, run pip uninstall opencv-contrib-python
2. Install this package:

pip install opencv-python

1. Import the package:

import cv2
