I noticed in both lua and pytorch implementation, the residual modules structure is `bn->relu->conv`. But the [resnet modules](https://github.com/pytorch/vision/blob/master/torchvision/models/resnet.py) are `conv->bn->relu`. Is there any particular reason why you modify the sequence...

Okay, so actually, this repo's residual module is not the same as the [demo](https://github.com/umich-vl/pose-hg-demo/blob/master/residual.lua) residual module. I feel the final demo version makes more sense, since it is the same...

Thanks for the note! I was wondering why [resent in pytorch model zoo](https://github.com/pytorch/vision/blob/master/torchvision/models/resnet.py) didn't adopt the `bn->relu->conv ` which everybody else seems to be using.
