Additional information

I was wondering if this issue will remain even if I deploy the app on azure or somewhere else. I want my app to use GPU but I want to be sure that the app gets deployed. If I deploy app using azure or similar would I face the same issues showing ‘please wait’ ?
If needed, add any other context about the problem here.
