Hi @vchoutas Thank you for your wonderful work!

With the help of smpl.forward().joints , 'smpl_poses' and 'smpl_trans' conver to 'keypoints3d' . But How to conver 'keypoints3d' to 'smpl_poses' and 'smpl_trans' ?

Hi, converting from 3d keypoints to SMPL poses is an inverse problem (which is also referred to as inverse kinematics) and thus it is much harder than the forward problem. This code might be helpful for you: https://github.com/CalciferZh/Minimal-IK
