问题描述
我使用model.save()保存了模型.我正在尝试重新加载模型并添加几层并调整一些超参数，但是，它会引发AttributeError.
I have a saved a model using model.save(). I'm trying to reload the model and add a few layers and tune some hyper-parameters, however, it throws the AttributeError.
使用load_model()加载模型.
我想我缺少了解如何将图层添加到保存的图层.如果有人可以指导我在这里，那就太好了.我是深度学习和使用keras的新手，所以我的要求可能很愚蠢.
I guess I'm missing understanding how to add layers to saved layers. If someone can guide me here, it will be great. I'm a novice to deep learning and using keras, so probably my request would be silly.
摘要:
prev_model = load_model('final_model.h5') # loading the previously saved model.
prev_model.add(Dense(256,activation='relu'))
prev_model.add(Dropout(0.5))
prev_model.add(Dense(1,activation='sigmoid'))
model = Model(inputs=prev_model.input, outputs=prev_model(prev_model.output))
及其引发的错误:
Traceback (most recent call last):
File "image_classifier_3.py", line 39, in <module>
prev_model.add(Dense(256,activation='relu'))
AttributeError: 'Model' object has no attribute 'add'
我知道添加图层适用于新的Sequential()模型，但是如何添加到现有的保存模型中呢?
I know adding layers works on new Sequential() model, but how do we add to existing saved models?
推荐答案
add方法仅存在于顺序模型( Sequential类)，这是一个功能更强大但更复杂的功能模型( Model类). load_model将始终返回Model实例，这是最通用的类.
The add method is present only in sequential models (Sequential class), which is a simpler interface to the more powerful but complicated functional model (Model class). load_model will always return a Model instance, which is the most generic class.
您可以看一下示例，以了解如何组合不同的模型，但是最终的想法是Model的行为与其他任何层都非常相似.因此，您应该可以:
You can look at the example to see how you can compose different models, but the idea is that, in the end, a Model behaves pretty much like any other layer. So you should be able to do:
prev_model = load_model('final_model.h5') # loading the previously saved model.
new_model = Sequential()
new_model.add(prev_model)
new_model.add(Dense(256,activation='relu'))
new_model.add(Dropout(0.5))
new_model.add(Dense(1,activation='sigmoid'))
new_model.compile(...)
