Dataset of 60,000 28x28 grayscale images of the 10 digits, along with a test set of 10,000 images.
dataset_mnist(path = "mnist.npz")
Path where to cache the dataset locally (relative to ~/.keras/datasets).
Lists of training and test data:
train$x, train$y, test$x, test$y, where
x is an array of grayscale image data with shape (num_samples, 28, 28) and
is an array of digit labels (integers in range 0-9) with shape (num_samples).
