[aarch64] DSX Blueprint Deployment Error on DGX Spark: Missing 'cgns' Dependency

Omniverse Learning and Resources Tutorials & Guides

Hello!

I am attempting to deploy the NVIDIA Omniverse DSX Blueprint on an NVIDIA DGX Spark system (Grace Blackwell CPU, aarch64 architecture).

While executing Step 4 of the “Quick Start” guide (./run_streaming.sh), the build process failed during the extension initialization. The logs indicate that the Packman package manager is unable to find the cgns dependency for the aarch64 platform on the remote servers.

Key Error Log:

Package 'cgns' at version '4.5.0-2-manylinux_2_35_aarch64-dynamic-release' is missing from local storage.
...
ERROR: BuildError: An error occured while pulling packman dependencies...
Package not found on specified remote servers! (name: cgns, version: 4.5.0-2-manylinux_2_35_aarch64-dynamic-release)

Questions:

  1. Are there official plans for the DSX Blueprint to support DGX Spark?
  2. Is there a workaround or a guide to manually compile the kit-cae extensions on ARM-based systems?

Thanks!

Hi and thanks for posting. At this time, the only thing for NVIDIA Omniverse we support of the DGX Spark is the very latest Isaac Sim build for arm64. That can be installed on the DGX Spark, but not our current blueprints. They require an x64 core architecture, because kit sdk still requires an x64 architecture.

Sorry about that. Hopefully in the future we are adding more support for the DGX Spark
