Failed to convert soup_can.onnx to engine file on Jetson Orin Nano

Hi, I’m trying to follow this tutorial: Tutorial for Isaac Manipulator Reference Workflows with Isaac Sim — isaac_ros_docs documentation

But couldn’t convert soup_can.onnx to engine file.

My goal is to finish the Manipulator tutorial to get a better know of it.
So, some questions:

  1. Does this mean DOPE is too large for Jetson to convert?
    • I do however, have another ketchup.onnx that’s convertible. Maybe it’s because the soup can onnx is exported with input tensor size 1920x1200? (The tutorial told me to do so, perhaps I can lower the camera resolution in Isaac Sim?)
  2. If this model is not applicable for Jetson Orin Nano, any alternative?
  3. And…when I launch ros2 launch isaac_manipulator_pick_and_place isaac_sim_workflows.launch.py, the RAM is being eaten up quickly (almost OOM). Is Isaac ROS Manipulator simply not suitable for Jetson Orin Nano, or it’s just this tutorial launch takes too much memory?

Some extra info:
Jetson Orin Nano 8G
JetPack 6.2.1
Isaac ROS 3.2 Docker container

Thanks!

I hoped I could upload the onnx and data file, sadly the forum forbids uploading onnx file, plus it restricts upload size to 100M.

Well it’s a size problem…trtexec is able to convert the 640x480 one. I can only size down the image first then? Anyway to change the resolution in Isaac sim?

Also is the tutorial suitable for Jetson Orin Nano? (Sorry I couldn’t find other examples because I don’t have AGX Orin at hand. But following an example is the fastest way to get familiar with sth).

Alright I’ll open another thread discussing the Manipulator.
