Training Error

[handhp1]

Hi, Thanks to nice work!

During training vto-dataset, I got an error below:

Traceback (most recent call last):
  File "train_frame_based.py", line 231, in <module>

    body_pos_combined = torch.stack([body_pos0, body_pos], dim=0)
TypeError: expected Tensor as element 0 in argument 0, but got NoneType

How can I fix this? ( There is no body_pos. )
For base_deformation, body_pos is needed.

#def get_repr_from_pos
  if base_deformation is None:
      body_pos_combined = torch.stack([body_pos0, body_pos], dim=0)
      base_deformation = self.repr_get_base_deform(vert_pos_gt[-1:], body_pos_combined, cfg=cfg)[0]

I used the option provided as an example and it worked. Thank you.
