FLutter Android Issue: MissingPluginException(No implementation found for method loadModel on channel tflite)

[kalpeshTOPS]

i am facing issue with loading models in android devices. Its working on ios device.

i have implemented below method

initTiflite() async { try { await Tflite.loadModel( model: "assets/yolov2_tiny.tflite", labels: "assets/yolov2_tiny.txt", numThreads: 1, isAsset: true, useGpuDelegate: false, ); print("Model loaded successfully"); } catch (e) { print("Error loading TensorFlow Lite model: $e"); } }

Can you anyone help me with this?

Can you share your pubspec.yaml file that contains tflite?

Thanks.

I see that you haven't added the assets for your model and library. Could you please include them as outlined in the README.md file?

You can link the library like this.

tflite:
    git:
      url: https://github.com/sumn2u/flutter_tflite.git
      ref: main

I added an example application in the repo for reference.

Thanks.

I am able to load model success fully but i got android app crash while object detection.

i tried below code variation to detect object from live stream

1) var detector = await Tflite.detectObjectOnFrame( bytesList: image.planes.map((plane) { return plane.bytes; }).toList(), model: "YOLO", imageHeight: image.height, imageWidth: image.width, imageMean: 0, imageStd: 255, numResultsPerClass: 1, threshold: 0.3, );

2) var detector = await Tflite.runModelOnFrame( bytesList: image.planes.map((plane) { return plane.bytes; }).toList(), imageHeight: image.height, imageWidth: image.width, // imageMean: 127.5, // imageStd: 127.5, // rotation: 90, numResults: 6, threshold: 0.05, asynch: true);

error i am getting is like below

PlatformException (PlatformException(Failed to run model, Interpreter busy, java.lang.RuntimeException: Interpreter busy at sq.flutter.tflite.TflitePlugin$TfliteTask.(TflitePlugin.java:486) at sq.flutter.tflite.TflitePlugin$RunYOLO.(TflitePlugin.java:777) at sq.flutter.tflite.TflitePlugin.detectObjectOnFrame(TflitePlugin.java:675) at sq.flutter.tflite.TflitePlugin.onMethodCall(TflitePlugin.java:169) at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:267) at io.flutter.embedding.engine.dart.DartMessenger.invokeHandler(DartMessenger.java:292) at io.flutter.embedding.engine.dart.DartMessenger.lambda$dispatchMessageToQueue$0$io-flutter-embedding-engine-dart-DartMessenger(DartMessenger.java:319) at io.flutter.embedding.engine.dart.DartMessenger$$ExternalSyntheticLambda0.run(Unknown Source:12) at android.os.Handler.handleCallback(Handler.java:958) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:230) at android.os.Looper.loop(Looper.java:319) at android.app.ActivityThread.main(ActivityThread.java:8919) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:578) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1103) , null))

Can you please help me with this?

It's really hard to detect the issue based on the provided error message. Can you try running example application attached in this repo?

[kalpeshTOPS]

Ok I will try. But the example only contains the object detected over the image not on the camera live frame.
