keras的ImageDataGenerator.flow_from_directioy错误显示Found 0 images belonging to 6 classes.

题主按照python深度学习这本书练习keras，在猫狗分类的问题使用flow_from_directory遇到问题
书上的结果是生成器最终生成

但是在我的编译器上生成的是

路径应该也没有错误如图

使用的keras版本号2.3.4，tf版本号2.3.0
希望能帮助我解答

关于使用flow_from_directory时，文件目录结构很重要，参照如下文章构建一下训练集、测试集及验证集的文件目录结构。

Keras ImageDataGenerator with flow_from_directory() - Machine Learning Tutorials Keras’ ImageDataGenerator class allows the users to perform image augmentation while training the model. If you do not have sufficient knowledge about data augmentation, please refer to this tutorial which has explained the various transformation methods with examples. You can also refer this Keras’ ImageDataGenerator tutorial which has explained how this ImageDataGenerator class work.
