DIPP-Differentiable Integrated Prediction and Planning

This repo is the implementation of the following paper:

Differentiable Integrated Motion Prediction and Planning with Learnable Cost Function for Autonomous Driving
Zhiyu Huang, Haochen Liu, Jingda Wu, Chen Lv
AutoMan Research Lab, Nanyang Technological University
[Project Website]

Dataset

Download the Waymo Open Motion Dataset v1.1; only the files in uncompressed/scenario/training_20s are needed. Place the downloaded files into training and testing folders separately.

Installation

Install dependency

sudo apt-get install libsuitesparse-dev

Create conda env

conda env create -f environment.yml
conda activate DIPP

Install Theseus

Install the Theseus library, follow the guidelines.

Usage

Data Processing

Run data_process.py to process the raw data for training. This will convert the original data format into a set of .npz files, each containing the data of a scene with the AV and surrounding agents. You need to specify the file path to the original data and the path to save the processed data. You can optionally use multiprocessing to speed up the processing.

python data_process.py \
--load_path /path/to/original/data \
--save_path /output/path/to/processed/data \
--use_multiprocessing

Training

Run train.py to learn the predictor and planner (if set --use_planning). You need to specify the file paths to training data and validation data. Leave other arguments vacant to use the default setting.

python train.py \
--name DIPP \
--train_set /path/to/train/data \
--valid_set /path/to/valid/data \
--use_planning \
--seed 42 \
--num_workers 8 \
--pretrain_epochs 5 \
--train_epochs 20 \
--batch_size 32 \
--learning_rate 2e-4 \
--device cuda

Open-loop testing

Run open_loop_test.py to test the trained planner in an open-loop manner. You need to specify the path to the original test dataset (path to the folder) and also the file path to the trained model. Set --render to visualize the results and set --save to save the rendered images.

python open_loop_test.py \
--name open_loop \
--test_set /path/to/original/test/data \
--model_path /path/to/saved/model \
--use_planning \
--render \
--save \
--device cpu

Closed-loop testing

Run closed_loop_test.py to do closed-loop testing. You need to specify the file path to the original test data (a single file) and also the file path to the trained model. Set --render to visualize the results and set --save to save the videos.

python closed_loop_test.py \
--name closed_loop \
--test_file /path/to/original/test/data \
--model_path /path/to/saved/model \
--use_planning \
--render \
--save \
--device cpu
