Cuda installtion

I have jetson nano, with ubuntu 20.04 on it. I am trying to use the Gpu of my jetson. I tried to install cuda but it didnt work. Is there any tutorial or guide on how to use cuda or the GPU of the jetson?

The usual method to set up your jetson would be to use a JetPack to install things, or else use the SDK manager. The JetPack link includes a link to a webinar and other get-started resources. The SDK Manager link has quickstart instructions on that page.

Also, for Jetson related inquiries, you may wish to ask on the relevant jetson forum corresponding to the type of jetson you have.
