They are just placeholders for tag-values. Please just ignore them.

And how about scores [0.8049]? How to define scores.

All scores are changed to 1.0, as suggested by MSCOCO Team.

All scores are changed to 1.0, as suggested by MSCOCO Team. Where is the reference? Sorry, I cant understand the scores define.

I only have two things. one is the scores represent the person score. the other is the scores represent all keypoint scores. So the value is higher, it is visible keypoint. Thanks

The following is copied from https://cocodataset.org/#format-results

Note: keypoint coordinates are floats measured from the top left image corner (and are 0-indexed). We recommend rounding coordinates to the nearest pixel to reduce file size. Note also that the visibility flags vi are not currently used (except for controlling visualization), we recommend simply setting vi=1.
