Mastering OpenCV 4 with Python

Installing Python on Linux

On Debian derivatives such as Ubuntu, use APT to install Python. Afterwards, it is recommended to upgrade the pip version. pip (https://pip.pypa.io/en/stable/) is the PyPA (https://packaging.python.org/guides/tool-recommendations/) recommended tool for installing Python packages:

$ sudo apt-get install python3.7$ sudo pip install --upgrade pip

To verify that Python has been installed correctly, open a Command Prompt or shell and run the following command:

$ python3 --version Python 3.7.0
