GoMNIST is a Go driver for reading Yann LeCun's MNIST dataset of handwritten digits
The MNIST dataset is included. It is a copy from Yann LeCun's MNIST page.
How to use
Install the packages:
% go get github.com/petar/GoMNIST
Import them in your code as
% import "github.com/petar/GoMNIST"
Load the MNIST training and testing data sets into memory using

if err != nil {
…
}
Sweep through the samples
