Integrating OpenCV, Python and UE4

I’ve been working on a project and I wished to include a feature that allows players to upload an image to the system and do facial landmark detection for the image. But I am stuck at integrating these software and I watched the most famous tutorial of integrating opencv and UE4 but I failed and it seems like not what I really want as he is doing C++ but I would like to work on it with some python libraries. Are there any easier ways or tutorials for installing plugins and etc. ? Thank you.
