what i need to do !
you are missing the ‘odrive’ python module (it’s not the same as the odrivetool)
pip install odrive should install this module and you should be able to start the odrive_server.py script afther that.
The newest python never has all the modules built. Get an older version of Python 
my interface is connected but is not complete
run python in the command line to enter the python console and run:
import flask
and if you don’t get an error, then flask is there, if you get the same ‘ModuleNotFoundError’… install flask with pip install flask
