How to extract motion coef_dict["emotion"]

[Reachrich55]

Hello, I really appreciate your work. Your model uses '--rot_repr' =='emo' in the training script, which requires coef_dict to have an additional 'emotion' key. I would like to know:

1. What is the difference between this and the coefficient of motion represented by the axis angle.
2. How can I extract the motion coefficients coef_dict["emotion"]. （it's also the key to motion_feat_dim=73.）
   Thank you for your time.
