Hello @neo_cheng! According to your logs you are getting this error message:
[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.
The NVIDIA Tesla T4 does not have the Ray Tracing Tensor Cores required to run Omniverse. You can take a look at our * Technical Requirements for more information on system requirements.
I would like to suggest that you take a look at NVIDIA Omniverse Cloud where you can run Omniverse on the Cloud from any device, anywhere!
