Converting a GraphDef from the session.

converter = lite.TFLiteConverter.from_session(sess, in_tensors, out_tensors)
tflite_model = converter.convert()
open("converted_model.tflite", "wb").write(tflite_model)

Converting a GraphDef from file.

converter = lite.TFLiteConverter.from_frozen_graph(
graph_def_file, input_arrays, output_arrays)
tflite_model = converter.convert()
open("converted_model.tflite", "wb").write(tflite_model)

Converting a SavedModel.

converter = lite.TFLiteConverter.from_saved_model(saved_model_dir)
tflite_model = converter.convert()
