Jetson Orin cannot run object_detection_birds_view.py

Software Python

Hello,
I’m unable to run the “object_detection_birds_view.py” sample code on Jetson Orin Nano. It throws the following error. Any ideas on what I could be missing or doing wrong?

/usr/local/zed/samples/object detection/birds eye viewer/python$ python3 obj

Running object detection ... Press 'Esc' to quit

Are you running this remotely, with ssh -X, VNC or such a thing ?

Hello Antoine, I was running this directly on the machine itself.

There is something tricky with your system. Please run sudo apt install --reinstall nvidia-jetpack, it should do the trick.

I ran the reinstall command as you mentioned but it did not help. I also did a remove & install, no luck. I ended up commenting out all the code related to the OpenGL viewer and was able to run the scripts.

I see that the Jetpack 5.1.1 is the first version to support Jetson Orin nano. Could it be that it’s missing libraries that are required by OpenGL?

It’s probably something like that, We need to investigate. Thank you for reporting it.
