rosrun rqt_graph rqt_graph shows error NameError: name 'basestring' is not defined

I have started the ROS tutorials and when I try to run rqt_graph it gives me a basestring error.
I am using Ubuntu 16.04, and Kinetic distro. I am using python 3.5.2 using Anaconda.

Traceback (most recent call last): File "/opt/ros/kinetic/lib/rqt_graph/rqt_graph", line 8, in <module> sys.exit(main.main(sys.argv, standalone='rqt_graph.ros_graph.RosGraph')) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_gui/main.py", line 59, in main return super(Main, self).main(argv, standalone=standalone, plugin_argument_provider=plugin_argument_provider, plugin_manager_settings_prefix=str(hash(os.environ['ROS_PACKAGE_PATH']))) File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/main.py", line 349, in main from .perspective_manager import PerspectiveManager File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/perspective_manager.py", line 44, in <module> class PerspectiveManager(QObject): File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/perspective_manager.py", line 48, in PerspectiveManager perspective_changed_signal = Signal(basestring) NameError: name 'basestring' is not defined

I thought of proceeding for the time being, but I get same error on running rqt_console rqt_console; also in rqt_plot rqt_plot.

ROS officially only supports Python 2. So I would suggest you use that instead. Pull requests to make the code work with both Python versions are always welcome 😉

While addressing other tickets I took some time to at least fix the obvious syntax errors with Python. See the related PRs:

• use Python 3 compatible syntax #81
• use Python 3 compatible syntax rqt#113
• use Python 3 compatible syntax rqt_common_plugins#421
• use Python 3 compatible syntax rqt_robot_plugins#121

But I don't expect that everything and especially all plugins will work flawlessly in Python 3. Therefore I still recommend to use Python 2 for ROS.

Sure. Thanks.
