Meaning of keys in .pkl after running track.py

[JerryPW]

Hi! Thanks for your great work! As I finished running track.py and I got a .pkl file with following dict_keys(['time', 'shot', 'frame_path', 'tracked_ids', 'tracked_bbox', 'tid', 'bbox', 'tracked_time', 'appe', 'loca', 'pose', 'center', 'scale', 'size', 'img_path', 'img_name', 'class_name', 'conf', 'annotations', 'smpl', 'camera', 'camera_bbox', '3d_joints', '2d_joints', 'mask', 'extra_data']). Some of the keys are easy to understand like 'time', 'frame_path', however, some of the keys are really confused me like 'appe', 'tracked_bbox', 'bbox'... So, I wonder whether it is convenient for you to provide some detailed explanaion about the result after running track.py.

Furthermore, I noticed that some of the people can be detected when I run python demo.py independently on a single image, but can not be observed when running track.py in a video. Why is that happened?

Looking forward to your reply soon!
