Is this the totality of your configuration to run ROS with python 3.5? I've been trying to implement a similar configuration, but I've needed to install a significant number of additional libraries, and ROS still seems to be trying to use python2.7.

Edit: I'm trying to work with ROS Kinetic, which may be part of the issue.
