NuScenes

Download nuScenes V1.0 full dataset data and CAN bus expansion data HERE. Prepare nuscenes data by running

Download CAN bus expansion

# download 'can_bus.zip'
unzip can_bus.zip 
# move can_bus to data dir

Prepare nuScenes data

We genetate custom annotation files which are different from mmdet3d's

python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes --version v1.0 --canbus ./data

Using the above code will generate nuscenes_infos_temporal_{train,val}.pkl.
