Hi, @George_Soloupis, thank you for the reply. I simply ran the retrieval code by Colab.
And added the recommended method to convert the final model to tflite. That was:
converter = tf.lite.TFLiteConverter.from_saved_model(path) # path to the SavedModel directory
tflite_model = converter.convert()
You can see the error in the following image.
