'Android 12(Api Level 31): TfLiteGpuDelegate Invoke: GpuDelegate must run on the same thread where it was initialized
After upgrade my android os to version 12, my code stopped work, I use flutter plugin tflite_flutter 0.9.0 and I launch tflite in isolation.
It throws this error:
TfLiteGpuDelegate Invoke: GpuDelegate must run on the same thread where it was initialized.
E/tflite (20055): Node number 64 (TfLiteGpuDelegateV2) failed to invoke.
E/flutter (20055): [ERROR:flutter/runtime/dart_isolate.cc(1111)] Unhandled exception:
E/flutter (20055): Bad state: failed precondition
E/flutter (20055): #0 checkState (package:quiver/check.dart:74:5)

E/flutter (20055): #4 IsolateHelper.entryPoint (package:myai/ai/helper/isolate_helper.dart:51:30)
My code:
final gpuDelegateV2 = GpuDelegateV2(
options: GpuDelegateOptionsV2(
isPrecisionLossAllowed:true,
inferencePreference:TfLiteGpuInferenceUsage.preferenceSustainSpeed,
inferencePriority1:TfLiteGpuInferencePriority.minMemoryUsage,
inferencePriority2:TfLiteGpuInferencePriority.auto,
inferencePriority3:TfLiteGpuInferencePriority.auto,
)
);
var interpreterOptions = InterpreterOptions()..addDelegate(gpuDelegateV2);
_interpreter = interpreter ??
await Interpreter.fromAsset(
MODEL_FILE_NAME,
options: interpreterOptions
);
Anyone faced such problem? Any suggestions how to fix it?
