我正在尝试创建一个模型并将其适合Keras,但我收到一条消息,要求我编译它,尽管调用了compile()却没有错误
大部分代码来自在线教程,我对其进行了一些调整以适合我的设置(图像文件夹),但似乎无法对其进行调试。
train_datagen = ImageDataGenerator(
rescale=1./255,
shear_range=0.2,
zoom_range=0.2,
horizontal_flip=True)
test_datagen = ImageDataGenerator(rescale=1./255)
train_generator = train_datagen.flow_from_directory(
'data/train',
target_size=(150, 150),
batch_size=32,
class_mode='binary')
validation_generator = test_datagen.flow_from_directory(
'data/test',
target_size=(150, 150),
batch_size=32,
class_mode='binary')
model = Sequential()
model.add(Dense(64, activation='relu'))
model.add(BatchNormalization())
model.add(Dense(64, activation='relu'))
model.add(BatchNormalization())
model.add(Dropout(0.5))
model.add(Dense(10, activation='softmax'))
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
# fine-tune the model
model.fit_generator(
train_generator,
steps_per_epoch=50,
epochs=50,
validation_data=validation_generator,
validation_steps=50)
预期结果没有错误,但是我得到了:
"RuntimeError: You must compile your model before using it."
