Why the ResNeSt config file only have 'syncBN' version, such as 'cascade_rcnn_s50_fpn_syncbn-backbone+head_mstrain-range_1x_coco.py' #4503

I try to modify the config to BN and use only 1 card to train, and the result is not good.

I don't know if it has a negative effect but you can use ./tools/distr_train.py <config/file.py> 1 and train on only 1 card this way.

Hi @clw5180 The official ResNeSt implementation used SyncBN. We followed the same setting.
