What are the differences between 'Your_ResNet' and MMCV's ResNet vb/vc/vd

[sherwin-silin-chen]

I find your config file the backbone network is 'our_resnet'. I see the code of your resnet and want to know what are the differences between general resnet and yours? Could I load the checkpoint file in mmcv's resnet vb/vc/vd directly？

@sherwincn Actually they are no difference. Initially, we directly transfer the code used in classification to segmentation, thus we rename it our_resnet. When we use the mmcv's resnet for detection, we find the pretrained weights can also be loaded. You can refer to config of rsp_resnet50_dota

Thanks for your reply. I use the pretrained-model in mmsegmentation and load the params in mmcv's resnet without any changes. But your model's state_dict_keys aren't suitable with mmcv'resnet.
I get the log as follow:

@sherwincn Can you print the keys of two dicts separately?

[DotWang]

@sherwincn In resnet_in_det, we extra add a function def init_weights(self, pretrained=None):. In our_resnet_seg, we do a similar operation. So if you want to use resnet_seg, you also should remove unnecessary prefixes such as 'backbone' or 'module'
