ResNet Version 1.5 vs 2.0

[ScXfjiang]

Hi. I am confused with version of ResNet for training. Most of open materials shows that we should use ResNet 1.5 link. However, I found ResNet 2.0 is used actually in training results v0.7, which is based on another paper Identity Mappings in Deep Residual Networks and have structure diff with old version. Is either ResNet 1.5 and ResNet 2.0 allowed in submit?
