ROOT

Dear ROOT experts,

could you please help me in installing ROOT6 with python3 in Xbuntu 16.04, because I built it with:

cmake -Dpython3=ON -DPYTHON_EXECUTABLE=/usr/bin/python3.5 -DPYTHON_INCLUDE_DIR=/usr/include/python3.5/ -DPYTHON_LIBRARY=/usr/lib/python3.5/ …/root-6.12.04/

but in ipython did not recognize

In [1]: import ROOT

ImportError Traceback (most recent call last)
in ()
----> 1 import ROOT

ImportError: No module named ‘ROOT’

thank you in advance

You need to set $PYTHONPATH to $ROOTSYS/lib, to let Python know where you installed ROOT and be able to load the module. After that everything should work.
