Prerequisites

If you want to build the python version in order to modify or plug it in and existing pipe, here's what you need:

    * Python 3.7 + 
    * Cpp 11+
    * PyQt5
    * OpenCV2
    * PyOpenColorIO
    * OpenEXR

WARNING

If you are not on a x64 linux distribution, the custom c++ python modules will not run, you will need to recompile the using the tasks.py file in the cppModules folder Meanwhile, you can use the latest Windows compile release you can find on this github
