virtualenv (https://pypi.org/project/virtualenv/) is a very popular tool that creates isolated Python environments for Python libraries. virtualenv allows multiple Python projects that have different (and sometimes conflicting) requirements. In a technical way, virtualenv works by installing some files under a directory (for example, env/).

Additionally, an exact copy of the Python or Python3 binary is placed in this directory. Once this virtual environment is activated, you can install packages in the virtual environment using pip. virtualenv is also recommended by the PyPA (https://packaging.python.org/guides/tool-recommendations/). Therefore, we will see how to install OpenCV or any other...
