[oneway3124]

When I execute this following command: python -m pcdet.datasets.kitti.kitti_dataset create_kitti_infos tools/cfgs/dataset_configs/kitti_dataset.yaml

There are some errors as following, train sample_idx: 007476 train sample_idx: 007479 Traceback (most recent call last): File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/runpy.py", line 192, in _run_module_as_main return _run_code(code, main_globals, None, File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/runpy.py", line 85, in _run_code exec(code, run_globals) File "/home/lijiadi/wangwei/OpenPCDet/pcdet/datasets/kitti/kitti_dataset.py", line 479, in <module> create_kitti_infos( File "/home/lijiadi/wangwei/OpenPCDet/pcdet/datasets/kitti/kitti_dataset.py", line 443, in create_kitti_infos kitti_infos_train = dataset.get_infos(num_workers=workers, has_label=True, count_inside_pts=True) File "/home/lijiadi/wangwei/OpenPCDet/pcdet/datasets/kitti/kitti_dataset.py", line 222, in get_infos return list(infos) File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/concurrent/futures/_base.py", line 611, in result_iterator yield fs.pop().result() File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/concurrent/futures/_base.py", line 432, in result return self.__get_result() File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/concurrent/futures/_base.py", line 388, in __get_result raise self._exception File "/home/lijiadi/anaconda3/envs/OpenPCDet-ww/lib/python3.8/concurrent/futures/thread.py", line 57, in run result = self.fn(*self.args, **self.kwargs) File "/home/lijiadi/wangwei/OpenPCDet/pcdet/datasets/kitti/kitti_dataset.py", line 203, in process_single_scene points = self.get_lidar(sample_idx) File "/home/lijiadi/wangwei/OpenPCDet/pcdet/datasets/kitti/kitti_dataset.py", line 66, in get_lidar return np.fromfile(str(lidar_file), dtype=np.float32).reshape(-1, 4) ValueError: cannot reshape array of size 86881 into shape (4) (OpenPCDet-ww) lijiadi@lijiadi-Z490-UD:~/wangwei/OpenPCDet$

Can you help me about this issue?

did your kitti training dataset is 7481? "train sample_idx: 007476 train sample_idx: 007479",maybe you should check your kitii dataset.

I have checked these problem that there are 7481 samples for our dataset. I donot know why the log like this status?
