errors in merging two layers output

[tct...@gmail.com]

Hi, dear all, I have problem about merging two layers output, the code is listed as below:

input1 = Input(batch_shape=(shape[0],shape[1],I1_dim))
input2 = Input(batch_shape=(shape[0],shape[1],shape[2]-I1_dim))
test1 = LSTM(32)(input1)
test2 = LSTM(100)(input2)
encoded = Merge([input1,test2],mode='concat')

How can I fix this problem?

Thank you very much!

input1 = Input(batch_shape=(shape[0],shape[1],I1_dim))
input2 = Input(batch_shape=(shape[0],shape[1],shape[2]-I1_dim))
test1 = LSTM(32)(input1)
test2 = LSTM(100)(input2)

encoded = Merge([test1,test2],mode='concat') # put test1 not input1

Thank you, even I change it, it still does not work.

Hi,

 

Fix what problem? You have not told us what the actual problem is.

Sorry for missing. I am not with my computer now, but I remember it says the tensor variables does not have some method. The inputs that will be merged are tensor variables type.

When I change it like this:

input1 = Input(batch_shape=(shape[0],shape[1],I1_dim))
input2 = Input(batch_shape=(shape[0],shape[1],shape[2]-I1_dim))
test1 = LSTM(32)(input1)
test2 = LSTM(100)(input2)
encoded = Merge([test1,test2],mode='concat')

It has the error:

Thank you.

For the functional API you have to use merge (from keras.layers), not Merge. Note the case sensitivity.

Thank you, I got your reply. It works now.
