Error When Run QuickDemo

[zzqjh]

When I run QuickDemo, I got this error report.
could you have some suggestion for me please？

python3 demo.py --cfg_file cfgs/kitti_models/pv_rcnn.yaml --ckpt pv_rcnn_8369.pth --data_path /home/zzqjh/3D-OT/OpenPCDet/data/kitti/training/velodyne/000004.bin

You should download the pretrained models and use --ckpt to specify the path of downloaded model.
