Efficient Computation on Batched input

[zifanw]

Hi,

Thanks for your work in the robustness analysis for interpretations. I am curious if the code can do attack for batched data instead of one by one as the example shown in the notebook? I try to attack around 6000 images in Cifar and it seems to take > 6h on Titan Xp in a one-by-one manner.

Thanks.
