Is it possible to convert just 1 pose (not the full sequence) from AMASS to HumanML3D ?

What about SMPL to HumanML3D @EricGuo5513 ?

I also found this issue. process_file in motion_representation.ipynb gives exceptions for sequences of the length 1. I think that's because it can't calculate the velocity.

Yeah. Idk if I just pad the next frame with zeros, the output will make any sense.

@jojo978 did you find any solution to this ?

[EricGuo5513]

I think for 1 pose, you can skip the velocity features,

@EricGuo5513 I see. so to get the single pose, will I have to append maybe a dummy second pose so that the sequence is overall of length 2 ? also what are the indices of the velocity entries so I can zero them out ?

Hello, these are the meaning of each indices for a HumanML3D feature vector: # Recover global angle and positions for rotation data# root_rot_velocity (B, seq_len, 1)# root_linear_velocity (B, seq_len, 2)# root_y (B, seq_len, 1)# ric_data (B, seq_len, (joint_num - 1)*3)# rot_data (B, seq_len, (joint_num - 1)*6)# local_velocity (B, seq_len, joint_num*3)# foot contact (B, seq_len, 4) For a single pose, I guess you could have a dummy pose with z+ face direction, as the first pose. And you are not able to get the foot contact and local velocity. For the other features, they normally only need the global rotation velocity, which in your case is the root rotation of this single pose.
