Error occured when reimplementing pointpillar on vic3d dataset #12

Closed CatOneTwo closed 2 years ago

CatOneTwo commented 2 years ago

Hi, I have followed the configs/vic3d/late-fusion-pointcloud/pointpillars/README.md to prepare the dataset, but when I try to train PointPillar model with trainval_config_i.py, the error occurred as No such file or directory: '../../../../data/DAIR-V2X/cooperative-vehicle-infrastructure/infrastructure-side//kitti_infos_train.pkl.

I have checked the converted dataset, which indeed doesn't contain kitti_infos_train.pkl. So how can I generate this file, thank you!

You should convert the dataset with Kitti format into the format the MMDetection3D requires. More details refer to https://mmdetection3d.readthedocs.io/en/latest/data_preparation.html.

I had the same problem. Did you solve it? I saw the corresponding download link in the mmdet3d manual, but I don't think it's right.

I had some possible solutions but didn't implement them because I switched to using the V2X-set data set for now. The general idea is to follow the documentation for custom datasets in mmdet3d.
