title: how do i add a custom image dataset from kaggle to Metalhead.jl/Flux.jl julia
body: <p>I am new here.
  I have been trying to use Metalhead.jl/Flux.jl to train custom image classifiers but I cant seem to be able to load data from a folder directly. (Not part of the standard datasets).
  Say I have a folder with 10 sub folders -&gt; each of them with a 1000 images.
  How can I load this up to perform a simple leNet5 CNN task?</p>
  <p>Thank you!</p>
