How to get a layer's type in Keras?

Question

I'm trying to select the last Conv2D layer for a given (general) model. model.summary() provides a list of layers with their type, but how can I access this to find the layer of that type?

Output from model.summary():

Layer (type)                 Output Shape              Param #   
=================================================================
input_1 (InputLayer)         (None, 224, 224, 3)       0         
_________________________________________________________________
block1_conv1 (Conv2D)        (None, 224, 224, 64)      1792      
_________________________________________________________________
...

predictions (Dense)          (None, 1000)              4097000

Trainable params: 138,357,544
Non-trainable params: 0

Answer 1

I think what you are looking for is this:

layer.__class__.__name__

where layer is in

model.layers

Answer 2

You can iterate over model.layers in reverse order and check layer types via isinstance:

next(x for x in model.layers[::-1] if isinstance(x, keras.layers.Conv2D))
