DGX Station A100  
Ubuntu 20.04

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

```auto
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-nv  
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](https://docs.omniverse.nvidia.com/plat_omniverse/plat_omniverse/technical.html) 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](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-nv

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?

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`

See this link for more info:

Hi @sheikh-nv

I have tried to launch Isaac SIM via this command

> /home/ryan\_lin/.local/share/ov/pkg/isaac\_sim-2021.2.1/isaac-sim.sh --/renderer/activeGpu=1

but it shows

`2022-01-20 09:54:30 [1,025ms] [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.`

and

```auto
2022-01-20 09:54:30 [1,039ms] [Warning] [omni.gpu_foundation_factory.plugin] RT-capable GPU not found, switching to compatibility mode
2022-01-20 09:54:30 [1,039ms] [Error] [omni.gpu_foundation_factory.plugin] Failed to create GPU foundation!

2022-01-20 09:54:30 [1,039ms] [Error] [omni.kit.imgui_renderer.plugin] Invalid device attached to the default window!

```

**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

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:
