Rock 5b tensorflow lite NPU

Has anyone been able to run tensorflow lite on the NPU?

soemthing like this

You need to convert the tensorflow lite model to rknn model using x86_64 version of rknn toolkit 2, then you can use the converted model.

this looks like a great start thanks. how do I see where the NPU is, like does it connect through PCI or soemthing?
