如何合并LSTM图层？ （图层，而不是sequencial（）变量）

Question

我有这段代码：

<ion-select [(ngModel)]="select" [required]="true" [name]="value">
            <ion-option *ngFor="let optionObj of responseData.parentData">
                {{ optionObj?.ProblemId] }} - {{ optionObj?.ProblemDesc }}
            </ion-option>
</ion-select>

但是我收到了这个错误：

    lstm1=LSTM(40,
        input_shape=(5,5),
        dropout=0.2, recurrent_dropout=0.2,return_sequences=False)


    lstm2=LSTM(40,
        input_shape=(5, 5),
        dropout=0.2, recurrent_dropout=0.2,return_sequences=False)

    merged = merge([lstm1, lstm2], mode='concat',concat_axis=1)

我怎么能不使用Sequencial（）（使用merge而不是Merge）？

目标是使用具有输出维度的maxpool图层的输出提供此合并图层：

merged = merge([lstm1, lstm2], mode='concat',concat_axis=1)
File "/home/rjpg/anaconda3/lib/python3.6/site-
packages/keras/legacy/layers.py", line 470, in merge
return merge_layer(inputs)
File "/home/rjpg/anaconda3/lib/python3.6/site-
packages/keras/engine/topology.py", line 549, in __call__
input_shapes.append(K.int_shape(x_elem))
File "/home/rjpg/anaconda3/lib/python3.6/site-
packages/keras/backend/tensorflow_backend.py", line 451, in int_shape
shape = x.get_shape()
AttributeError: 'LSTM' object has no attribute 'get_shape'

谢谢

您的代码lstm1和lstm2是图层而不是输出

所以合并不起作用给予＆＃34;＆＃39; LSTM＆＃39;对象没有属性＆＃39; get_shape＆＃39;＆＃34;错误

像这样的第一个设计代码

inp = Input(...)
lstm1 = LSTM(...)(inp)
lstm2 = LSTM(...)(inp)
merged = merge([lstm1, lstm2], ...)
