我在下面的代码段中收到以下错误:
您必须使用dtype bool为占位符张量'bidirectional_1/keras_learning_phase'提供值
如果我添加了dropout图层model.add(Dropout(dropout))
,它就可以了.谁知道为什么?后端是Tensorflow,Keras 2.0.1
def prep_model1(embedding_layer1, embedding_layer2, dropout=0.5): model0 = Sequential() model0.add(embedding_layer1) model0.add(Bidirectional(LSTM(128, return_sequences=False, dropout=dropout))) model1 = Sequential() model1.add(embedding_layer2) model1.add(Bidirectional(LSTM(128, return_sequences=False, dropout=dropout))) model = Sequential() model.add(Merge([model0, model1], mode='concat', concat_axis=1)) #model.add(Dropout(dropout)) model.add(Dense(1, activation='sigmoid')) return model
vega.. 29
尝试导入K并在模型之前设置学习阶段.
from keras import backend as K K.set_learning_phase(1) #set learning phase
