About low and high value of uniform distribution in PGD attack (CIFAR-10)

Hi Eric,

Thank you for the code. It's awesome with all efficient training tricks.
I would like to ask your confirmation on the values of low and high value in CIFAR10/utils.py line 61, the delta is initialized in uniform distribution on each normalized channel.

delta[:, i, :, :].uniform_(-epsilon[i][0][0].item(), epsilon[0][0][0].item())

The high value is epsilon[0][0][0], wouldn't it be epsilon[i][0][0]?
I am new in this. Can you please confirm? If you specifically fix the high value, can you please explain me a little bit? Thank you for your valuable work again.

Thanks for noticing this! It was a typo and has been fixed (though it shouldn't matter too much either way).
