"""HalpeDataset for top-down pose estimation.
'https://github.com/Fang-Haoshu/Halpe-FullBody'
The dataset loads raw features and apply specified transforms
to return a dict containing the image tensors and other information.
Halpe keypoint indexes::
0-19: 20 body keypoints,
20-25: 6 foot keypoints,
26-93: 68 face keypoints,
94-135: 42 hand keypoints
In total, we have 136 keypoints for wholebody pose estimation.
Args:
ann_file (str): Path to the annotation file.
img_prefix (str): Path to a directory where images are held.
Default: None.
data_cfg (dict): config
pipeline (list[dict | callable]): A sequence of data transforms.
dataset_info (DatasetInfo): A class containing all dataset info.
test_mode (bool): Store True when building test or
validation dataset. Default: False.
