Actually, I was too soon to say it works now.
with
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
branches command works.
but upgrade fails on the other hand if I have
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..'
)))
then branches fails, but upgrade works.
