\usage{
dataset_mnist(path = "mnist.npz", convert = TRUE)
}
\arguments{
\item{path}{Path where to cache the dataset locally (relative to ~/.keras/datasets).}

\item{convert}{When \code{TRUE} (default) the datasets are returned as R arrays.
If \code{FALSE}, objects are returned as NumPy arrays.}
}
\value{
Lists of training and test data: \verb{train$x, train$y, test$x, test$y}, where
\code{x} is an array of grayscale image data with shape (num_samples, 28, 28) and \code{y}
is an array of digit labels (integers in range 0-9) with shape (num_samples).
