I think the only reason that FrozenBatchNorm exists is that they want BN to stay in eval mode and not update its parameters …
Web(norm): FrozenBatchNorm2d (num_features=64, eps=1e-05) This is something that is directly discussed in the paper : fine-tuning can adopt the pretraining batch statistics as fixed parameters [17]; however, freezing BN is invalid when training from scratch.
