-Fashion-MNIST is a dataset of Zalando's article images—consisting of a training set of
-60,000 examples and a test set of 10,000 examples. Each example is a 28x28 grayscale image,
-associated with a label from 10 classes. We intend Fashion-MNIST to serve as a direct drop-in
-replacement for the original MNIST dataset for benchmarking machine learning algorithms.
-It shares the same image size and structure of training and testing splits.
