Hi,

I try to run below github project with JetsonNX and JetPack4.6.

But we found errors like below;

admin@usr-desktop:/workspaces/isaac_ros-dev$ colcon build && . install/setup.bash

Question:
Are there anyone success to run this github project with JetsonNX?

We would appreciate if you tell us how to solve this issue.

Best regards,

Hi,

I can proceed this issue following guide in the same link.
Thank you.
“Run git lfs pull in each Isaac ROS repository you have checked out”

And I found another error in the same project below “Walkthroughs”

Hi,

Thank you for your help.
Do you have any update?

I would appreciate if you check the behavior with JetsonNX.

Yes, git-lfs will bring down the binaries to resolve your original issue as you discovered. For the Walkthrough mentioning rqt-image-view, this is expected to run on an x86 host, not on the Jetson NX. The ros-foxy-rqt-image-view package does not exist for aarch64/Ubuntu 18.04 (Jetpack 4.6) unfortunately.

Hi,

Thank you very much for your kindness.
I really appreciate your help.

I’d like to continue to check the behavior with x86 host.

Best regards,
