I tried multiple things, first even if I install the package before running
pylint it won't work except on one of my machines.
So I tried to narrow it down with setuptools :
Working with 0.9.8
Not working with 2.2 (ImportError)
Not working with 3.6 (ImportError)
I guess setuptools changed something concerning namespaces packages, bug or
not this is another story. I'll keep looking.
Thanks a lot Sylvain
