training detectron2 for hand keypoints detection, how to create keypoint_flip_map?

See original GitHub issue

❓ How to use Detectron2

Hi,

I wish to use detectron2 for detecting hand keypoints but do not know how to create values for keypoint_flip_map used in MetadataCatalog. My dataset contains 21 keypoints on a hand image which are not symmetric (like the person pose keypoints in coco). How do I determine which keypoints should be paired for the flip map?

Thanks

Hi I am trying to create a key point detector for a shelf, where there is no symmetry. I have set keypoint_flip_map to an empty list but I am still getting the following error

keypoints = keypoints[keypoint_hflip_indices, :]
IndexError: arrays used as indices must be of integer (or boolean) type

I think the code does not allow empty keypoint_flip_map.

I think it is allowed. Note that empty does not mean “not provided”. You still need to set it to an empty list.

Thank you. Yes, it allows empty keypoint_flip_map
