“ImageDataGenerator”对象没有“flow”“from”“dataframe”“属性”

Question

我正在为癌症检测Kaggle挑战建立一个图像分类器。这是我正在使用的代码。在

`train_datagen = ImageDataGenerator(rescale=1./255,
                                   validation_split=0.15
)

test_datagen = ImageDataGenerator(rescale=1./255)

train_path = MAIN_DIR + '/CancerTrain'
valid_path = MAIN_DIR + '/CancerTrain'



train_generator = train_datagen.flow_from_dataframe(
                dataframe = train_labels,
                directory=train_path,
                x_col = 'id',
                y_col = 'label',
                has_ext=False,
                subset='training',
                target_size=(96, 96),
                batch_size=64,
                class_mode='binary'
                )

validation_generator = train_datagen.flow_from_dataframe(
                dataframe=df,
                directory=valid_path,
                x_col = 'id',
                y_col = 'label',
                has_ext=False,
                subset='validation', # This is the trick to properly separate train and validation dataset
                target_size=(96, 96),
                batch_size=64,
                shuffle=False,
                class_mode='binary'
                )`

但是，每当我运行它时，都会出现以下错误：

^{pr2}$

我到处找遍了，似乎找不到解决办法。这个方法现在叫什么不同了吗？在

我在使用keras2.1.4时也遇到了同样的错误。我只是用pip install keras upgrade升级。Keras 2.2.4没有给出相同的错误。现在一切都好了。在
