Issue with import keras.layers.core.Merge as Merge (compatibility of keras 2 with previous keras version?)

[Jean-Patrick Pommier]

Hi,

A notebook in :

https://github.com/imlab-uiip/keras-segnet

starts with some imports:

from keras.layers.core import Layer, Dense, Dropout, Activation, Flatten, Reshape, Merge, Permute
from keras.layers.convolutional import Convolution2D, MaxPooling2D, UpSampling2D, ZeroPadding2D
from keras.layers.normalization import BatchNormalization
from keras.callbacks import ModelCheckpoint

from keras import backend as K

As I tried to run that cell,the Merge module seems to be unknown:

--------------------------------------------------------------------------- 
ImportError Traceback (most recent call last) <ipython-input-8-82cbf4fe5266> in <module>() 
----> 1 import keras.layers.core.Merge as Merge ImportError: No module named Merge 

I suppose this is because I have keras 2.02 installed.

Is there a turn around to import this module?

Thanks.

I think this has changed in 2. (But I never tried in 1.x) I follwed this: https://keras.io/getting-started/functional-api-guide/#multi-input-and-multi-output-models Apart from a missing 'import keras' on top that worked fine for me.

You can import the legacy Merge layer via `from keras.layers import Merge`.

But note that you should no longer be using it. Instead, use the functional API.

you have to use, from from keras.layers import merge ( instead ' M ' replace 'm' )

ok thanks it works with from keras.layers import merge
