Please see the original Fashion-MNIST Github page for the detailed information.
Most of the code is adopted from Ronan Collobert's MNIST for Torch users.
luarocks install https://raw.github.com/mingloo/fashion-mnist/master/rocks/fashion-mnist-scm-1.rockspec
local fashion_mnist = require 'fashion-mnist'
local trainset = fashion_mnist.traindataset()
local testset = fashion_mnist.testdataset()
print(trainset.size) -- to retrieve the size
print(testset.size) -- to retrieve the size
Then, the i-th example is retrieved with:
local ex = trainset[i]
local x = ex.x -- the input (a 28x28 ByteTensor)
local y = ex.y -- the label (0--9)
