Why does my code get this error,My code is as follows:`

from tensorflow.keras.src.preprocessing.image import ImageDataGenerator

`
This is the library I brought in,Then I used him,code follows:

validation_generator = train_datagen.flow_from_dataframe(
    val_data,
    './train',
    x_col='filename',
    y_col='category',
    target_size=Image_Size,
    class_mode='categorical',
    batch_size=Batch_Size
)

but the “Image_Size” and “Batch_Size” also report error ,Same error as above
Please help with the answer,thanks!!!
