Describe the bug

According to the README

If you want to generate 2D skeleton annotations of specified video, please install mmdetection and mmpose first, then use the following script to extract skeleton annotations of NTURGB+D video:

python ntu_pose_extraction.py S001C001P001R001A001_rgb.avi S001C001P001R001A001.pkl

this does give me keypoints but the shape is (1, 98, 17, 2) i.e 1 person, 98 frames, 17 keypoints, 2 coordinates. ie COCO format of 17 keypoints. It should be resulting in 25 keypoints instead.
