Hi @prakashssp077, Can you please share some reproducible code.
from tflite_flutter_helper.

I had this when I tried to run PoseNet on an image, the precondition fails where inputTensor bytelength is 4x the input byte's length.
from tflite_flutter_helper.

It seems that when loading the model from asset, _tensor in interpreter.dart already has 4x the number of bytes and trying to resizeInputTensor fails
from tflite_flutter_helper.

Steps to reproduce:

- run sh install.sh from example/image_classification
- build example/image_classification on Android emulator
- load any image from the emulator by tapping the bottom right button
from tflite_flutter_helper.

Ok false alarm, I had changed the package code and had to repair it using
flutter pub cache repair
from tflite_flutter_helper.
