Face landmarks & blazepose landmarks model's labels inquiry

the models output multiple labels with the following shape.

face_landmarks_detection/face_mesh

  • [1, 1404] (368 points of xyz)
  • [1, 1] (score?)
  • [1, 266] (???)

blazepose_3d/landmark/full (same with the heavy and lite version)

  • [1, 117] (39 keypoints of x,y,score?)
  • [1, 64, 64, 39] (???)
  • [1, 256, 256, 1] (mask)
  • [1, 1] (score?)
  • [1, 195] (39 keypoints of x,y,z,score?,?)

I’m having trouble to figure out the meaning of each tensor labels.
