I also encountered this problem, but can solved by:
- launch a terminal
- in the terminal:
export RMW_IMPLEMENTATION=rmw_fastrtps_cpp
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.local/share/ov/pkg/isaac_sim-2023.1.0/exts/omni.isaac.ros2_bridge/humble/lib
- then, launch isaac sim selector
./isaac-sim.selector.sh
–
assume you use ROS2 humble;
