"Cannot create interpreter" when attempting to use XNNPackDelegate or GpuDelegateV2 (Android 13).

[andynewman10]

Here is what I see in the log when attempting to use the GpuDelegateV2 on Android 13 (Google Pixel 6a), as suggested in the provided example files.

I/tflite  (13058): Created TensorFlow Lite delegate for GPU.
I/tflite  (13058): Initialized TensorFlow Lite runtime.
W/libc    (13058): Access denied finding property "ro.mediatek.platform"
W/libc    (13058): Access denied finding property "ro.chipname"
W/libc    (13058): Access denied finding property "ro.hardware.chipname"

No indication is given about where the error occurred.

It is raised in interpreter.dart, here:

  factory Interpreter._create(Model model, {InterpreterOptions? options}) {
    final interpreter = tfliteBinding.TfLiteInterpreterCreate(
        model.base, options?.base ?? cast<TfLiteInterpreterOptions>(nullptr));
    checkArgument(isNotNull(interpreter),
        message: 'Unable to create interpreter.');
    return Interpreter._(interpreter);
  }

When closing the debugger session, additional red text shows up (I am not sure this is linked to the issue or maybe this is a side effect of FFI and/or the debugger):

Shall I give additional permissions to the application?

Similarly, the XNNPackDelegate also fails for the same model (66MB in size, which is not very big!)
