Training script for separate localmotion infill pretraining.

[siddharthKatageri]

Hi @JiahaoPlus, @wuyan01

Currently, train_graspmotion.py has code for combined training of TrajFill and LocalMotionFill models.
Can you please provide the script for training the LocalMotionFill model separately on AMASS?

While training the LocalMotionFill model separately on AMASS, the trajectory input will be the ground truth trajectory of the motion, right?

Thanks!
