Question

这是我的代码，直到我仔细阅读为止，并且在运行之前我遇到了错误

tensorboard = TensorBoard(log_dir=f'logs\{NAME}')

filepath = "RNN_Final-{epoch:02d}-{val_accuracy:.3f}.hdf5"
checkpoint = ModelCheckpoint("models\{}.model".format(filepath, monitor='val_acc', verbose=10, save_best_only=True, mode='max'))

train_y= np.asarray(train_y) 
validation_y= np.asarray(validation_y)

history = model.fit(
    train_x, train_y,
    batch_size=BATCH_SIZE,
    epochs=EPOCHS,

    validation_data=(validation_x, validation_y),

    callbacks=[tensorboard, checkpoint])

这是错误：

KeyError: 'val_accuracy'

我该怎么办？

Answer 1

更改的名称

“ val_accuracy”到“ val_acc”

在filepath = "RNN_Final-{epoch:02d}-{val_accuracy:.3f}.hdf5"中，它应该可以工作。

我该如何解决该错误？我正在尝试运行模型，但始终收到此关键错误
