ModuleNotFoundError: No module named 'mmdet3d.ops.iou_loss.iou_loss_ext'

Hi, I strictly followed the installation instructions. But I always met this problem using the mmdetection v0.13.0 with the files in ../mmdet3d_full.

'
File "MUTR3D/mmdetection3d/mmdet3d/ops/iou_loss/sort.py", line 4, in
from .iou_loss_ext import sort_vertices_forward
ModuleNotFoundError: No module named 'mmdet3d.ops.iou_loss.iou_loss_ext'
'
It seems that the file iou_loss_ext.py is missing in mmdet3d/ops/iou_loss/.
Any suggestions? Could you help to solve it? Thanks.

I encountered the same problem and solved it by changing python version in conda env to 3.7. Guess that the cython-packaged iou_loss_ext SO file is restricted in python 3.7 env.
