Keras disconnected graphs example when using multiple models

	def test_connected_models(self):
	input1 = Input(shape=(100,))
	dense1 = Dense(1)(input1)

	input2 = Input(shape=(200,))
	dense2 = Dense(2)(input2)
	model2 = Model(input2, dense2)

	# This will work, because there are no intermediate Inputs.
