Error in pull the image

Hi Dear Isaac Sim team,

I was trying to pull a container from NGC using singularity for HPC:

singularity build --sandbox isaac-sim:2022.1.1 docker://nvcr.io/nvidia/isaac-sim:2022.1.1

An error occurs:
FATAL: While performing build: conveyor failed to get: Error reading manifest 2022.1.1 in nvcr.io/nvidia/isaac-sim: unauthorized: authentication required

The command was working with all other containers, any idea why it requires authentication?

Hi @yunchaoyang ,

We have the instruction for docker here:
https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/install_advanced_container_deployment.html#isaac-sim-setup-remote-headless-container

And we don’t officially support Singularity but customers are free to try.
