如何在keras python中保存模型？

Question

Model description:
cnn1=Sequential()
cnn1.add(Conv2D(128,(2,300), activation = 'relu',input_shape = (maxLenofSent,300,1)))

cnn1.add(MaxPooling2D(1,3))

cnn1.add(Flatten())
cnn1.add(Dense(100, activation = 'relu'))

cnn2=Sequential()
cnn2.add(Conv2D(128,(2,300), activation = 'relu',input_shape = (maxLenofSent,300,1)))
cnn2.add(MaxPooling2D(1,3))
cnn2.add(Flatten())
cnn2.add(Dense(100, activation = 'relu'))


classifier2=Sequential()
classifier2.add(Merge([cnn1,cnn2], mode='concat'))
classifier2.add(Dense(70,activation='sigmoid'))
classifier2.add(Dropout(0.2))
classifier2.add(Dense(2,activation='tanh'))
sgd = SGD(lr = 0.01, momentum = 0.9, decay=1e-2, nesterov = False)
classifier2.compile(loss = 'categorical_crossentropy', optimizer = sgd, metrics = ['accuracy'])

如何保存完整模型，以便以后用于测试。两个cnn的输出去ann进行分类。

Answer 1

在保存模型之前，您需要使用classifier2.fit()对其进行训练

https://keras.io/models/sequential/#fit

保存模型使用classifier2.save('filename.hdf5')

Answer 2

这里如何保存模型：

model_json = model.to_json()
with open("<path.json>", "w") as json_file:
    json_file.write(model_json)
model.save_weights("<path.hdf5>", overwrite=True)

如果您想在每个 epoch 保存模型和权重，请尝试搜索回调。
