Fatal error on TFLite delegate load

[oralian]

When trying to load the TFLite delagate:

import tflite_runtime.interpreter as tflite

armnn_delegate = tflite.load_delegate(
    library="/home/aurelien/Projects/PreBuilts-Binaries/ArmNN-linux-aarch64/libarmnnDelegate.so",
    options={"backends": "CpuAcc,GpuAcc,CpuRef", "logging-severity": "trace"}
)

But I get this error:

Info: ArmNN v30.0.0
(8240) PVR:(Fatal): Debug assertion failed! (uiNumValidDevices > 0) [ device.c:521 ]
Aborted

I'm using a Beaglebone AI-64:

My bad, I installed the incorrect OS for my Beaglebone. Oops, now it runs fine!
