  <p>Windows10, Python 3.6.8, tfv2.0.0 </p>
  
  <p>code:</p>
  
  <pre><code>import tensorflow as tf
  model=tf.keras.models.load_model("E:\h5\outputs\model.h5")
  converter = tf.lite.TFLiteConverter.from_keras_model(model)
  converter.experimental_new_converter = True
  tflite_model = converter.convert()
  open("E:\h5\converted_model.tflite", "wb").write(tflite_model)
