nuScenes

Download nuScenes V1.0 full dataset data, CAN bus and map(v1.3) extensions HERE, then follow the steps below to prepare the data.

Download nuScenes, CAN_bus and Map extensions

cd UniAD
mkdir data
# Download nuScenes V1.0 full dataset data directly to (or soft link to) UniAD/data/
# Download CAN_bus and Map(v1.3) extensions directly to (or soft link to) UniAD/data/nuscenes/

Prepare UniAD data info

Option1: We have already prepared the off-the-shelf data infos for you:

cd UniAD/data
mkdir infos && cd infos
wget https://github.com/OpenDriveLab/UniAD/releases/download/v1.0/nuscenes_infos_temporal_train.pkl  # train_infos
wget https://github.com/OpenDriveLab/UniAD/releases/download/v1.0/nuscenes_infos_temporal_val.pkl  # val_infos

Option2: You can also generate the data infos by yourself:

The generated data path will contain the root directory. Please remember to change the data_root to empty in config files if using your generated pkl. Refer to OpenDriveLab#13.

cd UniAD/data
mkdir infos
./tools/uniad_create_data.sh
# This will generate nuscenes_infos_temporal_{train,val}.pkl

Prepare Motion Anchors

cd UniAD/data
mkdir others && cd others
wget https://github.com/OpenDriveLab/UniAD/releases/download/v1.0/motion_anchor_infos_mode6.pkl
