Unable to get hidden layer activation of ANN

I am using python2 and i'm trying to get the activations of hidden layer. I am using the following code which is giving me an error:

get_activations = theano.function([my_model.layers[0].input], my_model.layers[0].get_output(train=False),
                              allow_input_downcast=True)

When I run the code it says:

AttributeError: 'Dense' object has no attribute 'get_output'

I have tried to use my_model.layers[0].output which also does not work correctly.

What should I do to get the activations from a layer given?

attribute get_output is only defined for old versions of keras (0.3). It no longer exists in version 1.0.

see new syntax (keras doc FAQ)

something like 

get_activations = K.function([model.layers[0].input], [model.layers[1].output])

should work since the hidden layer is the second layer in your model (i.e. model.layers[1])
