Context-Aware Timewise VAEs for Real-Time Vehicle Trajectory Prediction

Official implementation for Context-Aware Timewise VAEs for Real-Time Vehicle Trajectory Prediction.

Accepted by IEEE Robotics and Automation Letters. [arXiv][YouTube]

Dependencies

• Pytorch 1.11
• Numpy 1.21

We recommend to install all the requirements through Conda by

$ conda create --name <env> --file requirements.txt -c pytorch -c conda-forge

Code Usage

Train a model from scratch

$ python main.py \
    --train <train_data_dir> --test <test_data_dir> \
    --config <train_config_file> --ckpt <checkpoint_dir>

Evaluate a trained model

$ python main.py \
    --test <test_data_dir> \
    --config <eval_config_file> --ckpt <checkpoint_dir>

Data Preprocessing

See scripts/README.md for details of data preprocessing.

Train from scratch

We provide our configure files in config folder. To reproduce the results, please run

# nuScenes
$ python main.py \
    --train <data_dir>/train --test <data_dir>/val --map_dir <data_dir>/map \
    --config config/nuscenes_train.py --ckpt <checkpoint_dir>

# Lyft
$ python main.py \
    --train <data_dir>/train/0 --test <data_dir>/validate/0 --map_dir <data_dir>/map \
    --config config/lyft_train.py --ckpt <checkpoint_dir> \
    --rank 0 --workers 4
$ python main.py \
    --train <data_dir>/train/1 --test <data_dir>/validate/1 --map_dir <data_dir>/map \
    --config config/lyft_train.py --ckpt <checkpoint_dir> \
    --rank 1 --workers 4 --master_addr <master_addr>
$ python main.py \
    --train <data_dir>/train/2 --test <data_dir>/validate/2 --map_dir <data_dir>/map \
    --config config/lyft_train.py --ckpt <checkpoint_dir> \
    --rank 2 --workers 4 --master_addr <master_addr>
$ python main.py \
    --train <data_dir>/train/3 --test <data_dir>/validate/3 --map_dir <data_dir>/map \
    --config config/lyft_train.py --ckpt <checkpoint_dir> \
    --rank 3 --workers 4 --master_addr <master_addr>

# Waymo
$ python main.py \
    --train <data_dir>/training/0 --map_dir <data_dir>/map/training/0 \
    --test <data_dir>/validation/0  --test_map_dir <data_dir>/map/validation/0\
    --config config/waymo_train.py --ckpt <checkpoint_dir> \
    --rank 0 --workers 8
...
$ python main.py \
    --train <data_dir>/training/7 --map_dir <data_dir>/map/training/7 \
    --test <data_dir>/validation/7  --test_map_dir <data_dir>/map/validation/7\
    --config config/waymo_train.py --ckpt <checkpoint_dir> \
    --rank 7 --workers 8 --master_addr <master_addr>

We use distributed training for Lyft and Waymo datasets with 4 and 8 worker machines respectively. (cf. https://pytorch.org/docs/stable/distributed.html for Pytorch distributed training.)

All training was done with A100 GPUs for Lyft and Waymo datasets and a V100 GPU for nuScenes.

Evaluation

We also provided our pre-trained models in Release.

To reproduce the testing results, please run

$ python main.py \
    --test <data_dir>/val --map_dir <data_dir>/map \
    --config config/nuscenes_eval.py --ckpt models/nuscenes_res18

    --test <data_dir>/validate/0 --map_dir <data_dir>/map \
    --config config/lyft_eval.py --ckpt models/lyft_res152 \
    --rank 0 --workers 4
$ python main.py \
    --test <data_dir>/validate/1 --map_dir <data_dir>/map \
    --config config/lyft_eval.py --ckpt models/lyft_res152 \
    --rank 1 --workers 4 --master_addr <master_addr>
$ python main.py \
