How are the .pkl files in the poses of the training set obtained?

Hello, @AndresCasado
I'm very sorry to bother you again. Recently, I've encountered an issue regarding the .pkl files in the poses of my training dataset. Are these .pkl files simply obtained by processing the .ply files generated by the expose code through the smplx2smpl code, or are there further operations involved? Thank you for taking the time to read my message; I look forward to receiving your reply as soon as possible.
