有没有办法从之前保存的CNN模型中绘制准确性和损失图？还是只能在训练和评估模型期间绘制图表？

model = Sequential()
model.add(Conv2D(32, kernel_size=(3, 3),
                 activation='relu',
                 input_shape=input_shape))
model.add(Conv2D(64, (3, 3), activation='relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
model.add(Dropout(0.25))
model.add(Flatten())
model.add(Dense(128, activation='relu'))
model.add(Dropout(0.5))
model.add(Dense(_NUM_CLASSES, activation='softmax'))
model.compile(optimizer='rmsprop', loss='categorical_crossentropy',metrics= 
              ["accuracy"])
model.fit(x_train, y_train,
          batch_size=_BATCH_SIZE,
          epochs=_EPOCHS,
          verbose=1,
          validation_data=(x_test, y_test))
score = model.evaluate(x_test, y_test, verbose=0)
model.save('model.h5')
