   Thank you for the response!
   
   1) The page you linked has a nice example thanks! It'd be great if it was discoverable from [this page](https://mxnet.incubator.apache.org/architecture/note_data_loading.html).
   
   2) im2rec.py still has no docstrings, nor even a line of comments besides the license boilerplate :( It's really not trivial for someone who has no idea how im2rec works to figure out what is going on in there quickly.
   
   3) There's a slight misunderstanding. As I said in the original post, I tried to make my own .lst file *by hand*, following the example on the [doc page](https://mxnet.incubator.apache.org/faq/recordio.html) which at the time had integer labels. I wasn't using im2rec.py, as I gave up on understanding it, lacking an example and any docstrings/comments. I was just using Vim to write stuff :) This didn't work with mx.io.ImageRecordIter, because the labels must in fact be floats, not ints. However, the docs are now updated -- the labels are floats. So the problem is fixed :) Thanks!
