Tensorflow Lite Demo

As part of my requirements, have started deploying tensorflow models on Android using Tensorflow Lite
Amazing experience

import tensorflow as tf
# Convert to TensorFlow Lite model.
converter = tf.lite.TFLiteConverter.from_keras_model_file('sunroof_model.h5')
tflite_model = converter.convert()
open("sunroof_model.tflite", "wb").write(tflite_model)

Below are few errors have experienced while developing android code

"Attempt to invoke virtual method 'void org.tensorflow.lite.Interpreter.run(java.lang.Object, java.lang.Object)' on a null object reference"
Cannot copy between a TensorFlowLite tensor with shape [1, 1] and a Java object with shape [1].
Cannot copy between a TensorFlowLite tensor with shape [1, 6] and a Java object with shape [6].
