python - 类型错误 : fit_generator() got an unexpected keyword argument 'samples_per_epoch'

Question

定义每个时期的样本 = 233 和 nb_val_samples = 62 和时期 = 4 然后我得到错误

Type-error: fit_generator() got an unexpected keyword argument 'samples_per_epoch'

是什么导致了这个错误以及如何解决它？

history_object = model.fit_generator(train_generator, 
     samples_per_epoch=samples_per_epoch,
     validation_data=validation_generator,
     nb_val_samples=nb_val_samples, 
     nb_epoch=nb_epoch, verbose=1,
     callbacks=callbacks_list)

```

检查 documentations对于 fit_generator 的预期参数.至于你目前的情况，以下应该有效:

history_object = model.fit_generator(train_generator, 
                                     steps_per_epoch=samples_per_epoch,
                                      validation_data=validation_generator,
                                      validation_steps=nb_val_samples, 
                                     epochs=nb_epoch, verbose=1,
                                     callbacks=callbacks_list)
