Hi Yaniv,

I think you should take a look at this change [1].

Moreover, the project has started to purge all the python libraries installed
from the distros, as much as possible, and they should now fall back to the
pypi versions.

So I think your issue is a bug caused by the latest changes related to what I
wrote above...

Hope it helps you to understand.
