I have downloaded left color images, calibration, label, and velodyne dataset from the kitti 3d official website and also placed them to the folder by following the mmdetection3d official website , I also down load the txt files for data split

However when I run the last line "python tools/create_data.py kitti --root-path ./data/kitti --out-dir ./data/kitti --extra-tag kitti", there is an error saying index out of range. Could anyone give me some help?
