Hi,
My pytorch project encountered different behaviors in pytorch v0.1.12 and v0.4.0 (Discussion here https://github.com/xingyizhou/pytorch-pose-hg-3d/issues/16 5 and https://github.com/bearpaw/pytorch-pose/issues/33 3, just for reference, there is no need to look into the project in this topic though) and I have a firm reason to believe the problem lies in the BN layer. For debug purpose, is it possible for me to locally switch the BN implementation back to v0.1.12 in pytorch v0.4.0? Or can anyone tell me or point me to the files the exact changes of BN layer from v0.1.12 to after v0.2.0? Thanks very much!
