Keras - model.summary 不显示摘要。相反，它说的是'<... object at 0x12ff2dad0>>'

Question

这里是(我认为(代码的重要部分：

vgg_model = VGG16(include_top=False, weights='imagenet',input_shape=(img_width, img_height, 3))
model = Sequential()
model.add(vgg_model)
model.add(Flatten())
model.add(Dense(256, activation='relu'))
model.add(Dropout(0.5))
model.add(Dense(1, activation='sigmoid'))
print(model.summary) 

我在控制台中得到的不是模型摘要，而是：

Using TensorFlow backend.

<bound method Network.summary of <keras.engine.sequential.Sequential object at 0x12ff2dad0>>

我希望这个错误不在别的地方。请帮忙。

附言：我试着只询问vgg_model的摘要。同样的事情。

附言：我在MacBook或windows PC上运行这个并不重要。我尝试了不同的tf和Keras版本。总是一样的。。。

model.summary访问model对象的summary方法。要调用方法，请使用():

model.summary()  # no need for print()
