I use the envirment "docker pull yckimm/second:second_v1.5", and get this error.
could you fix it

Hi,

Launching this repo requires additional installation not mentioned in the instructions.
For this issue you need to install OpenPCDet and follow the INSTALL.md instructions.

Then you need to change line 10 of second/core/non_max_suppression/nms_gpu.py with the path relative to your OpenPCDet installation : sys.path.append('/<your path to OpenPCDet parent directory>/PCDet/pcdet/ops/iou3d_nms')

Hi, have you faced the problem
from spconv.utils import rbbox_iou, rbbox_iou_loss ImportError: cannot import name 'rbbox_iou_loss' ?
Could you tell me which spconv version you used? I have tried all the spconv various, but none of them applys 'rbbox_iou_loss'.
