    Description

      Importing ROOT from Python 2 works as expected, but importing from Python 3 results in this error:

      from ROOT import RooGaussian
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "/opt/root-6/lib/ROOT.py", line 24, in <module>
          import cppyy
        File "/opt/root-6/lib/cppyy.py", line 60, in <module>
          import libPyROOT as _backend
      ImportError: dynamic module does not define init function (PyInit_libPyROOT)
