Not enough data sets?

[h-enomoto]

Hello,

I hope this finds you well. I've been facing some challenges in successfully verifying the VAD, and I kindly seek your advice. I've followed the installation steps outlined in the documentation.

I have downloaded and extracted the necessary files from the NVIDIA website.

can_bus.zip
nuScenes-map-expansion-v1.3.zip
v1.0-trainval01_blobs.tar
v1.0-trainval02_blobs.tar
v1.0-trainval03_blobs.tgz
v1.0-trainval04_blobs.tgz
v1.0-trainval05_blobs.tgz
v1.0-trainval06_blobs.tgz
v1.0-trainval07_blobs.tgz
v1.0-trainval08_blobs.tgz
v1.0-trainval09_blobs.tgz
v1.0-trainval10_blobs.tgz
v1.0-test_blobs.tar
v1.0-test_meta.tar
v1.0-trainval_meta.tgz

I executed the command provided under the "Prepare nuScenes data" section. python tools/data_converter/vad_nuscenes_converter.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag vad_nuscenes --version v1.0 --canbus ./data

Unfortunately, this resulted in an error.

  File "tools/data_converter/vad_nuscenes_converter.py", line 988, in <module>
    nuscenes_data_prep(
  File "tools/data_converter/vad_nuscenes_converter.py", line 937, in nuscenes_data_prep
    create_nuscenes_infos(
  File "tools/data_converter/vad_nuscenes_converter.py", line 106, in create_nuscenes_infos
    train_nusc_infos, val_nusc_infos = _fill_trainval_infos(
  File "tools/data_converter/vad_nuscenes_converter.py", line 246, in _fill_trainval_infos
    mmcv.check_file_exist(lidar_path)
  File "/home/user1/miniconda3/envs/vad/lib/python3.8/site-packages/mmcv/utils/path.py", line 23, in check_file_exist
    raise FileNotFoundError(msg_tmpl.format(filename))
FileNotFoundError: file "./data/nuscenes/samples/LIDAR_TOP/n008-2018-08-01-16-03-27-0400__LIDAR_TOP__1533153857947444.pcd.bin" does not exist

While the directory does contain files, it appears that none of them are causing the error in question.

$ ls ~/VAD/data/nuscenes/samples/LIDAR_TOP/ -1 | wc -l
34149

Is it possible that a required file might be missing? I would greatly appreciate any guidance or support you can offer. Thank you for your time and consideration.

Best regards, enomoto
