The library in question seems to be

https://github.com/sevamoo/SOMPY

Given a package structure

sompy/
   __init__.py
   sompy.py
   ...

the line

from sompy import SOMFactory

is a relative import in Python 2 and fetches the name SOMFactory from the 
sompy.sompy submodule, but an absolute import in Python 3 which tries to 
access the (inexistent) sompy.SOMFactory from the file sompy/__init__.py.

Thus it looks like SOMPY requires Python 2.
