ImageIter with Multiple Labels only Get One Label

[jongchyisu]

Hi, I am using ImageIter to load multiple labels. I have used label_width=2 for generating rec files and also for ImageIter. I found that if I set shuffle=False, then it will only return one label (same label repeated twice) (the next_sample in image.py, the returned label only have one value), but I can get two labels correctly with shuffle=True. Is there something wrong?

Also, why the im2rec.py can generate both rec and idx files, but the bin/im2rec can only get rec file? How can I get idx file?

Thank you!
