The error you see is because you run the script with python3, which is probably the default python on your system. SUMO 0.29 did not work well with python3 so either use a more recent SUMO version or start the script with python2 like

python2 runner.py

Yes, probably that is the easiest solution if you do not need python 3 for other programs. – Michael Jan 24 '18 at 09:35
