Command suggestion

[hjpark83]

Hi, thank you for providing this great code.

I am trying to reproduce CHAMP, and I encountered some issues when running the smoothing SMPL command.
Please see the attached image — it shows the problems I ran into using the existing command.
If I change that command to below one, it works well.

blender --background --python scripts/data_processors/smpl/smooth_smpls.py -- --smpls_group_path driving_videos/your_video/smpl_results/smpls_group.npz --smoothed_result_path driving_videos/your_video/smpl_results/smpls_group.npz

I think that command should have double dash before 'smpls_group_path'.
Can you check it please?
Thanks a lot for your help.
