Hello! There is a one more issue with converter:

Traceback (most recent call last):
  File "convert_keras.py", line 114, in <module>
    main()

    graph = converter.convert(model)

    raise NotImplementedError('[KerasConverter] keras.layers.UpSampling2D is not supported')
NotImplementedError: [KerasConverter] keras.layers.UpSampling2D is not supported

will you add the UpSampling2D in future?
