Hi guys, I am learning about ROS2 on Windows 10 today, and when I run qt_graph, an error appeared as:

RosPluginProvider._parse_plugin_xml() plugin file "E:\dev\ros2-eloquent\ros2-windows\share\qt_gui_cpp/plugin.xml" in package "qt_gui_cpp" not found RosPluginProvider._parse_plugin_xml() plugin file "E:\dev\ros2-eloquent\ros2-windows\share\rqt_gui_cpp/plugin.xml" in package "rqt_gui_cpp" not found RosPluginProvider._parse_plugin_xml() plugin file "E:\dev\ros2-eloquent\ros2-windows\share\qt_gui_cpp/plugin.xml" in package "qt_gui_cpp" not found RosPluginProvider._parse_plugin_xml() plugin file "E:\dev\ros2-eloquent\ros2-windows\share\rqt_gui_cpp/plugin.xml" in package "rqt_gui_cpp" not found PluginHandlerDirect._restore_settings() plugin "rqt_graph/RosGraph#0" raised an exception: Traceback (most recent call last): File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\qt_gui\plugin_handler_direct.py", line 121, in _restore_settings self._plugin.restore_settings(plugin_settings_plugin, instance_settings_plugin) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\rqt_graph\ros_graph.py", line 265, in restore_settings self._refresh_rosgraph() File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\rqt_graph\ros_graph.py", line 293, in _refresh_rosgraph self._update_graph_view(self._generate_dotcode()) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\rqt_graph\ros_graph.py", line 334, in _update_graph_view self._redraw_graph_view() File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\rqt_graph\ros_graph.py", line 366, in _redraw_graph_view scene=self._scene) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\qt_dotgraph\dot_to_qt.py", line 263, in dotcode_to_qt_items edges = self.parse_edges(graph, nodes, highlight_level, same_label_siblings, scene=scene) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\qt_dotgraph\dot_to_qt.py", line 317, in parse_edges scene=scene) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\qt_dotgraph\dot_to_qt.py", line 221, in addEdgeItem style=style) File "E:\dev\ros2-eloquent\ros2-windows\Lib\site-packages\qt_dotgraph\edge_item.py", line 112, in init point2 = QPointF(float(parts[0]), -float(parts[1])) ValueError: could not convert string to float: '\\r\n46.336'

And I want to know how to fix this, so as to go on my learning. Thanks in advance!

On a simple graph I can't reproduce the problem. Can you please provide reproducible steps with which running nodes you experience the above errors.
