PlaftformException even after loading model
I have loaded model with Tflite.loadModel method and then after success Tflite.runModelOnFrame.
@override
void initState() {
super.initState();
// To display the current output from the camera,
// create a CameraController.
_controller = CameraController(
// Get a specific camera from the list of available cameras.
widget.camera,
// Define the resolution to use.
ResolutionPreset.medium,
);
_loadModel();
// Next, initialize the controller. This returns a Future.
_initializeControllerFuture = _controller.initialize().then((value) {
_controller.startImageStream((image) {
if (!_modelLoaded || !_detect) {
return;
}
try {
_startProcessing(image);
} catch (e) {}
});
});
}
_loadModel() async {
final res = await Tflite.loadModel(
model: "assets/models/car_detection/model_unquant.tflite",
labels: "assets/models/car_detection/labels.txt",
numThreads: 5, // defaults to 1
isAsset: true, // defaults to
);
print(res);
setState(() {
_modelLoaded = true;
});
}
_startProcessing(CameraImage image) async {
try {
Tflite.runModelOnFrame(
bytesList: image.planes.map((plane) {
return plane.bytes;
}).toList(),
imageHeight: image.height,
imageWidth: image.width,
numResults: 1,
asynch: true,
threshold: 0.5,
).then((value) => print(value));
} on PlatformException {}
}
I get below errors:

i was getting the same error. type in flutter run on the console and make sure your model it's loaded
@innerk Yes. I tried same earlier following one of the issue. My model loading returns success using Tflite.loadModel as mentioned in above code but no luck yet.
I have same issue. Here's my code
const IMAGE_MEAN = 127.5;
const IMAGE_STD = 127.5;
void runTfLiteTest(BuildContext context) async {
String res = await Tflite.loadModel(
model: "assets/tflite/deeplabv3_257_mv_gpu.tflite",
labels: "assets/tflite/labels.txt",
numThreads: 1,
isAsset: true,
useGpuDelegate: true
);
print("Model loaded $res"); //prints success
var result = await Tflite.runSegmentationOnImage( //crash on this line
path: "assets/tflite/256_test_0.png",
imageMean: IMAGE_MEAN,
imageStd: IMAGE_STD,
outputType: "png",
asynch: true
);
print(result);
}
And stacktrace:

Hi dear i face the same issue i solved by adding the following lines to my android/app/build.gradle aaptOptions { noCompress 'tflite' noCompress 'lite' }
Same issue is on my side too,
my code is running fine but result are not damn sure
Use Hawaii ml kit or google ml kit segmentation .
