Can I run it in headless mode using A100 GPU (Don’t need to visualize it)?
Yes. You can use WebSocket with H264 encoding if you need streaming.
It uses singularity to pull docker images, can I do that with ISAAC Sim, also does the docker image require an RTX GPU to work?
We have not tested with Singularity yet. You can try rebuild a container for Singularity based on our container.
Yes, The container requires and RTX GPU to run Isaac Sim.
