Hi all, I just started teh ROS2 manipulation basics course and when running the second shell commands
source /home/simulations/ros2_sims_ws/install/setup.bash
ros2 launch test_moveit_config moveit_rviz.launch.py
no graphical interface is launched. the shell shows no obvious error either:
ser:~$ ros2 launch test_moveit_config moveit_rviz.launch.py

[rviz2-1] Warning: class_loader.impl: SEVERE WARNING!!! A namespace collision has occurred with plugin factory for class rviz_default_plugins::displays::InteractiveMarkerDisplay. New factory will OVERWRITE existing one. This situation occurs when libraries containing plugins are directly linked against an executable (the one running right now generating this message). Please separate plugins outinto their own library or just don't link against the library and use either class_loader::ClassLoader/MultiLibraryClassLoader to open.
