i have same problem ++

django-kz commented 5 years ago

Guys @monder0116, @JohnTian Hi ! I encountered the same problem, I found a solution, but I am not sure that it is 100% correct. So what I did: `from keras.layers import concatenate concat_feat = concatenate([concat_feat, x], mode='concat', axis=concataxis, name='concat'+str(stage)+'_'+str(branch))

I replaced this line withmergetoconcatenate, becausemerge` seems to be deprecated invocation.

YingXiuHe commented 5 years ago

i solved this problem via reinstalled the Keras to 2.0.5 version.

@django-kz Thanks for sharing.

、、、 from keras.layers import concatenate concat_feat = concatenate([concat_feat, x], axis=concataxis, name='concat'+str(stage)+'_'+str(branch)) 、、、 in my win10,it works. But 、、、 from keras.layers import concatenate concat_feat = concatenate([concat_feat, x], mode='concat', axis=concataxis, name='concat'+str(stage)+'_'+str(branch)) 、、、 it don't work. I guess that is the version problem of keras. Mine:2.2.4

bitscott1102 commented 4 years ago

The latest version of Keras does not support concatenate

Use this Lambda

policy = Lambda(lambda x: x[0]-K.mean(x[0])+x[1], (NUM_ACTIONS,))([advantage, value])

hi, how to write the code? thanks.

Replace concatenate([concat_feat, x], mode='concat', axis=concat_axis, name='concat'+str(stage)+'_'+str(branch))

with policy = Lambda(lambda x: x[0]-K.mean(x[0])+x[1], (NUM_ACTIONS,))([advantage, value])(This is my code. ) https://www.tensorflow.org/api_docs/python/tf/keras/layers/Lambda
