def try_cv2_import()

The PyRobot python3 version which is a dependency of Habitat-PyRobot integration relies on ROS running in python2.7. In order to import cv2 in python3 we need to remove the python2.7 path from sys.path. To use the Habitat-PyRobot integration the user needs to export environment variable ROS_PATH which will look something like: /opt/ros/kinetic/lib/python2.7/dist-packages
