How to solve this problem?
FileNotFoundError: [Errno 2] No such file or directory: '/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/infos_train_10sweeps_withvelo.pkl'

I ran this command ‘python tools/create_data.py nuscenes_data_prep --root_path='/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/' --version="v1.0-trainval" --nsweeps=10’。
The error is as follows：
FileNotFoundError: [Errno 2] No such file or directory: '/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/infos_train_10sweeps_withvelo.pkl'

remove quote symbol in root_path='/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/'

I have removed the quotes from the command, but the error still exists.

@QYWT Same problem, have you solve this problem?

[tianweiy]

@lqzhao @QYWT Change the https://github.com/poodarchu/Det3D/blob/ed0f5418c6c9b06fc5f4b73888703a9a19c2947f/tools/create_data.py#L26 to

        Path(root_path) / "infos_train_{:02d}sweeps_withvelo_filter_True.pkl".format(nsweeps),

[tianweiy]

@poodarchu can you fix this? I changed the info name to reflect the filtering.

[QYWT]

@tianweiy Thank you for your advice. I have another question, where and how should I update dataset setting and path?
Update dataset setting and path
dataset_type = "NuScenesDataset"
n_sweeps = 10
data_root = "/data/Datasets/nuScenes"
db_info_path="/data/Datasets/nuScenes/dbinfos_train.pkl"
train_anno = "/data/Datasets/nuScenes/infos_train_10sweeps_withvelo.pkl"
val_anno = "/data/Datasets/nuScenes/infos_val_10sweeps_withvelo.pkl"
