How to get the "translations" and "rotations" parameters from the 'person_parameters' generated by Frankmocap?

[Haiyan-Jiang]

The hand parameters generated from Frankmocap include '['pred_vertices_smpl', 'pred_joints_smpl', 'faces', 'bbox_scale_ratio', 'bbox_top_left', 'pred_camera', 'img_cropped', 'pred_hand_pose', 'pred_hand_betas', 'pred_vertices_img', 'pred_joints_img']' in my test. So I cannot find the "translations" and "rotations" parameters which needed in the jointopt.py. How can I solve this problem?
