Isaac Ros no Data available

Dear Support

I hope that you can help me. After fighting through this description: Setting up Isaac™ ROS to work with ZED Cameras in ROS 2 - Stereolabs

There something is mentioned with Authorization required…

To keep that running I did:

xhost +local:root

and

./scripts/run_dev.sh -i ros2_humble.zed
-a “–runtime nvidia
-e DISPLAY=$DISPLAY
-v /tmp/.X11-unix:/tmp/.X11-unix
-v /usr/local/zed/settings:/usr/local/zed/settings
-v /usr/local/zed/resources:/usr/local/zed/resources”

Running isaac_ros_dev-aarch64-container
Creating non-root container ‘admin’ for host user uid=1000:gid=1000
Sourcing entryrypoint extension: /usr/local/bin/scripts/entrypoint_additions/zed-entrypoint.sh
Checking ZED SDK…

  • /usr/local/zed/ exists. Changing permissions
  • ZED SDK available:
    Stereolabs ZED SDK Version : 5.1.1
  • Stopping hotplug events dispatcher systemd-udevd [ OK ]
  • Starting hotplug events dispatcher systemd-udevd [ OK ]
    To run a command as administrator (user “root”), use “sudo ”.
    See “man sudo_root” for details.

When I build and start the Ros2 topic as described here:

ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zed2i enable_ipc:=false

I entered the running container in another command windows and wanted to test the topics. But whatever Topic I am doing echo with there still no data comes out-.

What can I do to get it also for April tag?

Here an Example where no data comes out. It is on the second terminal which I entered with docker exec -it bash

root@ubuntu:/workspaces/isaac_ros-dev# ros2 topic list
/clicked_point
/diagnostics
/parameter_events
/rosout

/zed/zed_node/status/health
/zed/zed_node/status/heartbeat

root@ubuntu:/workspaces/isaac_ros-dev# ros2 topic echo /zed/zed_node/imu/data

Nothing comes out no matter which topic.

I also tested it on a normal PC not only Jetson.

What can I do?
