Can't use ros2 launch yolo_bringup yolo.launch.py stuck when starting script. AGX Orin 64gb Developer kit

Its been like this for a long time and it doesnt move at all. I installed all the requirements and did everything like the guide said.

"Please verify the input topic that the node is subscribing to by checking it in RViz or using ros2 topic echo. Also, ensure that the camera topic is correctly set and that data is being published on the topic.

For example, you can check the camera topic with:
ros2 topic echo /image_raw

Try launching your file using the following command:
ros2 launch yolo_bringup yolo.launch.py input_image_topic:=<your_topic>

Hello, I am facing the same issue.

To simulate the camera input, I am publishing the image to /camera/rgb/image_raw, and I can preview it in Rviz2, where it displays correctly.

However, the /yolo/dbg_image node still does not produce any output.

Here is a screenshot of my terminal showing the following image

I hope to receive your reply and assistance, as I would appreciate your help in understanding this issue. Thank you very much for your time and support.

Check the QoS of the /camera/rgb/image_raw and also check if the detection topics are publishing. The QoS of the publisher and subscriber must be the same.

[Johnny-Hu-406]

First, I use ros2 topic info /camera/rgb/image_raw --verbose to confirm that the QoS settings of the publisher and subscriber nodes appear to be consistent.

Additionally, I also use ros2 docker --report to check the relationship between the publisher node and the subscriber node.

I’m not sure what other directions I can try to solve this issue. Any suggestions? Thanks!

@Johnny-Hu-406, try ros2 topic echo /yolo/detections and ros2 topic echo /yolo/tracking to check if detection and tracking are getting done.

[Johnny-Hu-406]

@mgonzs13 When executing ros2 topic echo /yolo/detections, I can see the following output, and ros2 topic echo /yolo/tracking also has similar output.

[mgonzs13]

That means you are getting detections. Next, check the topics of the /yolo/debug_node. Also, try ros2 topic echo /yolo/dbg_image.

[Johnny-Hu-406]

First, I tried ros2 topic echo /yolo/detections and could see the output, such as coordinates and confidence

After that, I tried ros2 topic echo /yolo/dbg_image, but there was no output in the terminal.
Then, the terminal gets stuck on the following screen.

I believe that /yolo/debug_node successfully receives input, but it is unable to output images to the /yolo/dbg_image topic. Additionally, ros2 topic echo /yolo/dbg_image does not produce a response. I'm not sure how to resolve this issue.

[mgonzs13]

So, if the problem is in the /yolo/debug_node, check the QoS of its topics, include the image and detection topics.

[Johnny-Hu-406]

I use ros2 topic info /camera/rgb/image_raw --verbose to confirm that the QoS settings of the /camera/rgb/image_raw and /yolo/debug_node nodes appear to be consistent.

@Johnny-Hu-406 are you using a depth camera? If not or if you don't want 3D detection, use use_3d:=False in your ros2 launch command.

[Johnny-Hu-406]

@mgonzs13 I'm not entirely sure what caused the issue, but after reinstalling your repository and Docker, the problem was successfully resolved.
Currently, the images from /yolo/debug_node are functioning properly.

I sincerely appreciate your patience and prompt responses—they have been incredibly helpful to me!
