Converting SMPL to SMPLX and saving prameters in axis angle format.

[SnehithR]

I want to convert SMPL paramters into SMPLX paramters in axis angle format. The pose paramters are in rotation matrix format and when I try to convert them into axis angle and load using smplx.create() method i can see slight translation in Y-axis and change in hands pose compared to the mesh saved while fitting SMPL to SMPLX. I was using scipy to convert rotaion matrix into rotvec.

TIA.
