import quat_to_mat

[RauchLukas]

Hi I am trying to run the GVO example

python 02_run_GVO.py --mode=test --gpu=0 --data_set=PCPNet --ckpt_dirs=230209_002534_GVO --ckpt_iters=800 --normal_init=./log/230208_021652_PCPNet/test_40000/pred_normal

But struggle with this import error:

root@50949d3b33ce:/NGLO# python 02_run_GVO.py --mode=train --gpu=0
Traceback (most recent call last):
  File "/NGLO/train.py", line 12, in <module>
    from net.NGLO import GVO
  File "/NGLO/net/NGLO.py", line 7, in <module>
    from .encode import EncodeNet
  File "/NGLO/net/encode.py", line 4, in <module>
    from .base import knn_group_v2, get_knn_idx, Conv1D
  File "/NGLO/net/base.py", line 223, in <module>
    import quat_to_mat
ModuleNotFoundError: No module named 'quat_to_mat'

Where is the import of the quat_to_mat! supposed to be coming from?

NGLO/net/base.py

Line 223 in b815f9c

import quat_to_mat

I can not trace back the file or python package to make available for this import.
Thanks for your help!
