Oh. Really, import ROOT works with python but not with python3. So this was a point.
Following this answer http://stackoverflow.com/a/37857536/2324000 I managed to have python2 and python 3 kernels. However, no influence on the previous error. Maybe I dont know how to start jupyter of python2.
Now, I think, what you mean by your question. I would like to have root built with python3, it is going to be a future soon. I have no idea what could I do, though… Could you tell me more? Thank you

Edit: I see now that python3 was a topic Feb 2016 … Jupyter Notebook with python3 (Python3.4) and ROOT
and there is probably a way Problem using ROOT with jupyter notebook
