K.function doesn't work

[KiddoZhu]

Hi
I follow your code to get the hidden layer output of an RNN. But it failed when I using K.function([model.layers[0].input], [model.layers[-1].output]), which causes an error:

MissingInputError: ("An input of the graph, used to compute DimShuffle{x,x}(keras_learning_phase), was not provided and not given a value.Use the Theano flag exception_verbosity='high',for more information on this error.", keras_learning_phase)

So is there any trick in your code? Or probably because I load model with model_from_json and model.load_weights?

The problem is solved. It is because I use dropout in my network.
