installing requirements

[GBrics]

I carefully followed the steps described in the readme but I'm getting errors when trying to install all the requirements using :
sudo -H pip3 install -r requirements.txt
(Option2 isn't working neither, modifications on pyjson5 didn't fix the issue)

Reported error :

Problem was coming from the python3 version. I did not manage to put a version of python higher than 3.7 as default on this version of ubuntu (16.04). Problem fixed by changing ubuntu version to a more recent one.
