when I use SN instead of BN, there is a big difference between val acc and train acc #8
Description
when i use your code resnetv2sn50 ,it is normal difference between val and train(maybe ,i only run 10 epochs).
but when i use my CNN model), there is a big difference between val acc and train acc,like this:

What should I pay attention to? I found you change order between bn(sn) and conv ,is it important?
