Hello, thank u for your awesome job! When I try to use the pv_rcnn_focal_lidar.yaml to train, there was an error occured:
UnboundLocalError: local variable 'mv_height' referenced before assignmentthe full error is:

UnboundLocalError: local variable 'mv_height' referenced before assignment
and I set the
USE_ROAD_PLANE : FALSEin pv_rcnn_focal_lidar.yaml , because my custom dataset don't have the road plane data, but then I try to use KITTI data, the same error still occured.I try to google this error, it seems like that this vraiable is not defined before the reference. I try to check out the mv_height in /FocalsConv/OpenPCDet/tools/../pcdet/datasets/augmentor/database_sampler.py. line 403, in call:
mv_height = mv_height[valid_mask]But I don't understand what wrong with this, if u can help me, I'd be very appreciated! Thanks!
