    If you're going to use opencv with Python, the easiest way to install opencv on a Raspberry Pi is: pip3 install opencv-python and pip3 install opencv-contrib-python. Using these commands, you'll not need to download additional or unnecessary files. It is to be noticed that this method works only on Raspbian Stretch and above and Python 3 ( This method does not work with Raspbian Jessy and Python 2)

  • @singrium What version of OpenCV is installed with this method? 2 or 3?

    If you don't specify the version by yourself, it will download the latest version which is 3.4.2, but if you want a specific version: run this pip3 install opencv-python == <version number> and pip3 install opencv-contrib-python == <version number>

    Did this error occur when you tried the commands above or when you did import cv2 ? Opencv have some dependencies that you should install first: run these commands to install the needed packages, then install Opencv sudo apt-get install libatlas-base-dev sudo apt-get install libjasper-dev sudo apt-get install libqtgui4 sudo apt-get install python3-pyqt5
