Running python3 script in ROS Kinetic

edit

I'm new to ROS and I'm having a problem with using a python3 script in ROS. I have a specific library that's only compatible with Python3 and I need a ROS Subscriber to use that library. I can't figure this out. Can someone explain me how I should do this?

UPDATE The error which I receive when I start my listener with "python3 listener.py"

Traceback (most recent call last):
