Error launching the ROS node

[jocacace]

Hi Guys,

I am using Ubuntu 22.04 with the docker image to start ROS2 packages from nvidia. I am trying the tutorial of this example, sadly, ran the isaac_ros_unet node, with the isaac_ros_unet_triton.launch.py launch file I have the following error:

[component_container_mt-1] 2022-10-14 13:21:04.108 ERROR gxf/std/entity_executor.cpp@200: Entity with 100 not found!

Any suggestion?

Running the container on Jammy should be fine. Could you attach more of the log though? The error is probably further up.

This is the whole error:

Thanks, that helps. It looks like it could not find the model file which you'll need to download from NGC and put in place. Take a look at steps 5-7 of the Quickstart if you haven't already.
