Issue with "Building and Deploying Digital Twin Applications With Omniverse Kit App Streaming" Course – Blank Screen and GPU Error

[je.kim]

Hello,

I recently purchased the “Building and Deploying Digital Twin Applications With Omniverse Kit App Streaming” course and have been following the steps as instructed.

Course Detail | NVIDIA

However, after executing ./repo.sh launch -- --no-window in the kit-app-template folder and running npm run dev in the web-viewer-sample folder, I tried to access the browser page, but only a blank screen appeared.

Upon checking the terminal where I launched ./repo.sh launch -- --no-window, I found the following error message that has been stuck for over 4 hours:

1mgu1.cpython-310-x86_64-L1nux-gnu.solstd::__deta1l::_Map_base<std::string, std::pair<std::string const, void*>,

In case it was related to GPU availability, I ran nvidia-smi, but it returned:
“No devices were found.”

I also contacted DLI support via email, but I haven’t received any response for over a week.

Could someone please help me resolve this issue?

Thank you in advance.

Hi and thanks for posting. Well if no devices are found, then that is pretty much saying your GPU is not found or it is not setup correctly. What hardware are you using? What GPU? What drivers? You need to be on Linux or PC with either Windows or Ubuntu. You need a modern RTX GPU at least a 3070 and the correct drivers.

Rather than running the “no window” command, first just try to run the actual kit app directly. Does it launch? Hold off on the streaming part until you confirm the actual kit app works.

I received the mail that it was done today and I checked and it came out as normal. Thank you!

Oh good. Strange but good
