Why there isn't a way to obtain the '/4d_humans' folder?

In the code, it is necessary to use a 'smpl_optimized_aligned_scale.npz' file in '4d_humans' folder, but I can not find the corresponding ways to obtain these data, which is also not indicated in README.md.

Maybe ml-hugs is not suitable for a custom dataset, due to the relatively complex implementation of dataset preprocessing.
