densent训练出错

[growvv]

当我执行下面这句话时 res = model.fit_generator(cc1, steps_per_epoch =3279601// batch_size, epochs = 100, validation_data =cc2 , validation_steps = 364400// batch_size, callbacks =[earlystop,checkpoint,tensorboard], verbose=1 ) 出现如下错误： Epoch 1/100

StopIteration Traceback (most recent call last) in () 4 validation_data =cc2 , 5 validation_steps = 364400// batch_size, ----> 6 callbacks =[earlystop,checkpoint,tensorboard] 7 )

StopIteration: 请问，这个要如何解决？
