Using integrated GPU and EXLA?

Hey gang, I’m running a Livebook locally on a machine that has an onboard graphics card.

Processor: AMD Ryzen™ 7 PRO 6850U with Radeon™ Graphics × 16

I’m seeing some mixed answers about if this is supported by the rocm backend or not.

I can try to set the default backend client like so:

Nx.default_backend({EXLA.Backend, client: :rocm}) 

But the error message I’m seeing seems like it’s looking for ”cuda”

** (exit) exited in: GenServer.call(EXLA.Client, {:client, :rocm, [platform: :rocm]}, :infinity)
    ** (EXIT) an exception was raised:
        ** (RuntimeError) Could not find registered platform with name: "cuda". Available platform names are: Host

Anyone run into this before? Am I just missing some config?
