How to get 'without bn' weights from 'bnnomerge' weights?

[alasin]

The performance of icnet_cityscapes_train_30k.caffemodel is better than icnet_cityscapes_train_30k_bnnomerge.caffemodel, however the trained model is supposed to output the latter model file. How is the conversion done between the two model weights and what's the reason behind it? I couldn't get it from the information in the note provided. Thanks!
