Keras 属性错误：'；功能'；对象没有属性'；设置#u模型'；

我正在使用keras拟合模型，并将回调列表传递给模型拟合生成器，但遇到以下错误。请帮助

AttributeError:“function”对象没有属性“set\u model”

代码段：

    from keras.callbacks import LearningRateScheduler
    import numpy as np
    from keras import optimizers
    from keras.callbacks import *

    def lr_schedule(epoch):
        lrate = 0.1
        if epoch > 50:
            lrate = 0.01
        elif epoch > 75:
            lrate = 0.001       
        return lrate


    filepath="latest_weight_ckpt_{epoch:02d}_{val_acc:.2f}.hdf5"
    model_ckpt = ModelCheckpoint(filepath, monitor='val_acc', verbose=1, 
    save_best_only=True, mode='max')
    #lists = [model_ckpt]


    #model_checkpoint= ModelCheckpoint("weights/DenseNet-BC-100-12- 
    CIFAR100.h5", monitor="val_acc", 
    save_best_only=True,save_weights_only=True)

    callbacks_list=[lr_schedule, model_ckpt]

    model.fit_generator(train_generator, epochs=25, 
    steps_per_epoch=200,verbose=1, validation_steps=200, 
    validation_data=validation_generator,callbacks=callbacks_list)

问题是，您正在将python函数（

lr_schedule

）作为回调传递，而不是作为Keras回调对象传递。您应该使用Keras

LearningRateScheduler

回调，如下所示：

lr = LearningRateScheduler(lr_schedule)
callbacks_list=[lr, model_ckpt]
