我正在尝试可视化我的模型的训练图，但出现此错误：

    Traceback (most recent call last):
    File "train.py", line 120, in <module>
    plt.plot(H.history['acc'])
    KeyError: 'acc'

&这里是完整的代码：

     # set the matplotlib backend so figures can be saved in the background
     import matplotlib
     matplotlib.use("Agg")

     # import the necessary packages
     from pyimagesearch.resnet import ResNet
     from sklearn.preprocessing import LabelEncoder
     from sklearn.model_selection import train_test_split
     from sklearn.metrics import classification_report
     from keras.preprocessing.image import ImageDataGenerator
     from keras.optimizers import SGD
     from keras.utils import np_utils
     from imutils import paths
     import matplotlib.pyplot as plt
     import numpy as np
     import argparse
