I am currently trying to make a facial recognition workflow with Orange but since the widgets are still prototypes they are not all available in Orange. I found the Github files for the widgets but don't know how to install this so that I can see and use the widgets in Orange.
There are three ways to install Orange add-ons:
Options -> Add-onsmenu of Orange.
pip3 install orange3-prototypes
Install from the source:
git clone https://github.com/biolab/orange3-prototypes.git cd orange3-prototypes python3 setup.py install
