If it’s not running, everything looks good, but if it’s running, the viewport window will go black or flash.
Just run the official example：
Isaac Examples → ROS2 → Isaac ROS → Sample Scene
There are no error outputs on the command line.
@Vulcan.Shao Can you start isaac sim with these flags:
--/rendergraph/mgpu/backend=copyQueue --/app/gatherRenderResults=1 --/app/uiGather=0
If this works its likely because IOMMU is not disabled in the BIOS, you should see a warnings/message in the terminal when starting up isaac sim. Disabling IOMMU should also resolve the issue.
Thank you very much, Hammad_S and your colleagues, for your prompt response and resolution of my issue. I have successfully tested this method and it has resolved my problem. Thanks.
Also, I would like to take this opportunity to inquire if the example of subscribing to image messages on a 3-card A6000 server can only run at around 30fps. Is this due to ROS data communication slowing down the entire program? I think my hardware configuration is already very good.
Looking forward to your reply or suggestion. Sincerely thank you!
