When I try to prepare kitti data, I get following error:

I have the same problem. Have you solved it

sixcomicpen commented 2 years ago

you can add "parents=True,exist_ok=True" into Det3D-master/det3d/datasets/kitti/kitti_common.py 179,like: Path.mkdir(v_path.parent.parent / (v_path.parent.stem + "_reduced"),parents=True,exist_ok=True)
