I have a trained model that I've exported the weights and want to partially load into another model. My model is built in Keras using TensorFlow as backend.
model = Sequential()
model.add(Conv2D(32, (3, 3), input_shape=input_shape, trainable=False))
model.add(Activation('relu', trainable=False))
model.add(MaxPooling2D(pool_size=(2, 2)))
model.add(Conv2D(32, (3, 3), trainable=False))
model.add(Activation('relu', trainable=False))
model.add(MaxPooling2D(pool_size=(2, 2)))
model.add(Conv2D(64, (3, 3), trainable=True))
model.add(Activation('relu', trainable=True))
model.add(MaxPooling2D(pool_size=(2, 2)))
model.add(Flatten())
model.add(Dense(64))
model.add(Activation('relu'))
model.add(Dropout(0.5))
model.add(Dense(1))
model.add(Activation('sigmoid'))
model.compile(loss='binary_crossentropy',
optimizer='rmsprop',
metrics=['accuracy'])
model.load_weights("image_500.h5")
model.pop()
model.pop()
model.pop()
model.pop()
model.pop()
model.pop()
model.add(Conv2D(1, (6, 6),strides=(1, 1), trainable=True))
model.add(Activation('relu', trainable=True))
model.compile(loss='binary_crossentropy',
optimizer='rmsprop',
metrics=['accuracy'])
I'm sure it's a terrible way to do it, although it works.
