label_desc: Use image node_id 1 to create a new FragmentKitti object from inherited base classes: BaseKitti, GeneralFragment with example: obj = FragmentKitti(root, mode, _supervised, min_size_block, max_size_block, max_dist_overlap, max_time_distance, min_dist, transform, pre_transform, pre_filter, is_online_matching, num_pos_pairs, ss_transform, min_points)
