Introduction

This reposity is the official PyTorch Lightning implementation for ST-P3.

TL;DR: we propose a spatial-temporal feature learning scheme towards a set of more representative features for perception, prediction and planning tasks simultaneously in autonomous driving, and thus devise an explicit pipeline to generate planning trajectories directly from raw sensor inputs.

Get Started

Setup

conda env create -f environment.yml
git clone https://github.com/OpenDriveLab/ST-P3.git

Pre-trained models

• open-loop planning on nuScenes: model.
• closed-loop planning on CARLA: model.

Evaluation

To evaluate the model on nuScenes:

• Download the nuScenes dataset.
• Download the pretrained weights.

bash scripts/eval_plan.sh ${checkpoint} ${dataroot}

To evaluate the model on CARLA:

• Please refer to the Transfuser to set up the environment.
• Test with the carla_agent.py file and the pretrained weights.

Training

# (recommended) perception module pretrain
bash scripts/train_perceive.sh ${configs} ${dataroot}

# (optional) prediction module training purpose, no need for e2e training
bash scripts/train_prediction.sh ${configs} ${dataroot} ${pretrained}

# entire model e2e training
bash scripts/train_plan.sh ${configs} ${dataroot} ${pretrained}

• To train the model from scratch on nuScenes, we recommend to train a perceptual weight first and use it to train subsequent tasks to prevent nan during training.
• If you would like to use the nuScenes depth data (will be released very soon), put the depth folder in the dataroot directory and change GT_DEPTH in the config file to True.

Benchmark

• Open-loop planning results on nuScenes.
