Key 'center' and 'scale' missing from result list

[PeteBai]

I used my own dataset for testing purposes. The config file is hrnet_w32_ap10k_256x256. I have downloaded the pre-trained model and removed evaluation code since I don't have ground truth. I have to manually add these 2 keys to the result dict in top_down_transform.py and shared_transform.py to make the code work. Did I miss something?

Also the upper and lower bound of where the prediction region ends also seems to be related to the center coordinates.

The same to me. Have you fixed that problem?

I find the reason. The Config module from mmcv cannot correctly load the dict(type='TopDownGetBboxCenterScale'), in the config file, so the 'scale' and 'center' will disappear. I have no idea how this happens as I look into the source code of mmcv and seems it misses that transform in the beginning.
But one simple way to fix it is to add:
new_transform = {'type': 'TopDownGetBboxCenterScale'} if new_transform not in transforms: transforms.insert(1,new_transform)
in the 'shared_transform.py' right under the 'self.transform = []'
