I install ros kinetic on Ubuntu 16.04, with python 2.7. rqt_graph shows properly, however, when I run rosrun rqt_gui rqt_gui and rosrun rqt_reconfigure rqt_reconfigure. It shows the following message, my $PYTHONPATH is /usr/lib/python2.7/dist-packages:/opt/ros/kinetic/lib/python2.7/dist-packages.
ros-kinetic-python-qt-binding is already installed.
