当我运行flowers_tf_lite.ipynb
脚本时。
Link to flowers_tf_lite.ipynb script
遇到KeyError: 'accuracy'
错误时,程序停止运行。
如何解决此类错误?
acc = history.history['accuracy']
val_acc = history.history['val_accuracy']
loss = history.history['loss']
val_loss = history.history['val_loss']
plt.figure(figsize=(8, 8))
plt.subplot(2, 1, 1)
plt.plot(acc, label='Training Accuracy')
plt.plot(val_acc, label='Validation Accuracy')
plt.legend(loc='lower right')
plt.ylabel('Accuracy')
plt.ylim([min(plt.ylim()),1])
plt.title('Training and Validation Accuracy')
plt.subplot(2, 1, 2)
plt.plot(loss, label='Training Loss')
plt.plot(val_loss, label='Validation Loss')
plt.legend(loc='upper right')
plt.ylabel('Cross Entropy')
plt.ylim([0,1.0])
plt.title('Training and Validation Loss')
plt.xlabel('epoch')
plt.show()
答案 0 :(得分:1)
模型编译后,精度指标分别命名为'acc'和'val_acc',您可以使用
进行确认model.metrics_names
这将为您提供
['loss','acc','val_acc']
所以您只需要在代码上方更改前两行
acc = history.history['acc']
val_acc = history.history['val_acc']
