Thank you Cédric, I'll try tomorrow.
I tried these lines, in this order
>>> from proteus import config, Model, Wizard, Report
>>> config = config.set_trytond('sqlite:///:memory:')
because this is what I saw here
https://github.com/tryton/proteus
So I understand that I should run
>>> config = config.set_trytond('sqlite:///:memory:')
as a first step ?
I'll try
