Error occured during the installation of IsaaC SIM

DGX Station A100
Ubuntu 20.04

Hi.
While trying to install Isaac SIM from Omniverse launcher, i got the following error:

Error occurred during installation of Isaac Sim: Command failed: "/home/userabc/.local/share/ov/pkg/isaac_sim-2021.2.1/omni.isaac.sim.post.install.sh"
ln: failed to create symbolic link 'extension_examples/examples': File exists

What should I do next before I install it again? Should I clean up something first?

Hi try uninstalling that version of Isaac Sim then remove the folder below if it exists.
/home/userabc/.local/share/ov/pkg/isaac_sim-2021.2.1
Next reinstall Isaac Sim.

Thanks @Sheikh_Dawood
BTW, does Isaac SIM require RTX series GPU to run?
It seems that I cannot host Isaac SIM on DGX A100 workstation according to this doc under Omniverse.

Yes.

It should be fine running Isaac Sim on an A100. Here is our System Requirements page:
https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/requirements.html

Can you please confirm that the A100 is connected using PCIE? This is version of A100 is required (compared to the non PCIE version) if you are using livestreaming from the DGX Station. It has NVENC support.

Hi @Sheikh_Dawood

Driver version: 470.57.02
CUDA version 11.04

May I know how to check A100 is connected using PCIE?

After reinstalling Isaac SIM, I got the following error log, does that mean the GPU on my DGX A100 workstation is not connected using PCIE?

2022-01-12 02:11:58 [1,686ms] [Error] [gpu.foundation.plugin] No device could be created. Some known system issues:

  • The driver is not installed properly and requires a clean re-install.
  • Your GPUs do not support RayTracing: DXR or Vulkan ray_tracing, or hardware is excluded due to performance.
  • The driver cannot enumerate any GPU: driver, display or a docker issue. For Vulkan, test it with Vulkaninfo tool from Vulkan SDK, instead of nvidia-smi.
  • For Ubuntu, it requires server-xorg-core 1.20.7+ and a display to work without --no-window.
  • For Linux dockers, the setup is not complete. Install the latest driver, xServer and NVIDIA container runtime.

Please share the output of nvidia-smi. You should be able to run Isaac Sim. Only the livestreaming feature may not be working if it is not a PCIE version.
You can also try updating the drivers.

Try running Isaac Sim with this flag to select the GPU:
--/renderer/activeGpu=1

I don’t get it, it’s very obvious that I have 5 GPUs (index 0 ~ 4) according to nvidia-smi

here is the complete error log

2022-01-20 09:54:30 [1,025ms] [Error] [gpu.foundation.plugin] No device could be created. Some known system issues:
- The driver is not installed properly and requires a clean re-install.
- Your GPUs do not support RayTracing: DXR or Vulkan ray_tracing, or hardware is excluded due to performance.
- The driver cannot enumerate any GPU: driver, display or a docker issue. For Vulkan, test it with Vulkaninfo tool from Vulkan SDK, instead of nvidia-smi.
- For Ubuntu, it requires server-xorg-core 1.20.7+ and a display to work without --no-window.
- For Linux dockers, the setup is not complete. Install the latest driver, xServer and NVIDIA container runtime.

I have also tried other GPU index (0 ~ 4) to launch

GPU 0 gave me this error
2022-01-20 10:05:01 [1,153ms] [Warning] [gpu.foundation.plugin] Raytracing is not supported on GPU: 0. Skipping this device.

and other indexes gave me this error
2022-01-20 10:06:16 [680ms] [Error] [gpu.foundation.plugin] The chosen activeGpu index is higher than the available GPUs. An unsupported driver might also prevent it from enumerating your devices properly.

Hi, it could be caused by incompatible drivers. Please try this datacenter drivers:
