I executed the following in Ubuntu 16.04 LTS for ROS Kinetic on the terminal:

roscore (on terminal 1)

rqt_graph (on terminal 2)

But on terminal 2, it gave me the following error:

PluginHandlerDirect._restore_settings() plugin "rqt_graph/RosGraph#0" raised an exception: Traceback (most recent call last): File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/plugin_handler_direct.py", line 116, in _restore_settings self._plugin.restore_settings(plugin_settings_plugin, instance_settings_plugin) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_graph/ros_graph.py", line 203, in restore_settings self._refresh_rosgraph() File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_graph/ros_graph.py", line 227, in _refresh_rosgraph self._update_graph_view(self._generate_dotcode()) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_graph/ros_graph.py", line 260, in _update_graph_view self._redraw_graph_view() File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_graph/ros_graph.py", line 293, in _redraw_graph_view same_label_siblings=True) File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_dotgraph/dot_to_qt.py", line 254, in dotcode_to_qt_items graph.nodes_iter = graph.get_node_list AttributeError: 'list' object has no attribute 'get_node_list'

Could anyone help me out resolve this issue.
