将各层添加到sequential()函数中
形成一个整体
from keras.models import Sequential
from keras.layers import Dense, Activationmodel = Sequential([Dense(32, input_shape=(784,)),Activation('relu'),Dense(10),Activation('softmax'),
])
利用add函数一层一层地往上加
model = Sequential()
model.add(Dense(32, input_dim=784))
model.add(Activation('relu'))
