Trajectory Prediction with Graph-based Dual-scale Context Fusion

Introduction

(Update Aug 4 2022)

• Add (DDP-based) multi-card training/evaluation/submission code.
• Fix some parameters, update links to the pretrained model.

(NEW) This paper is accepted for publication in the Proceedings of the 2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2022).

Install dependencies

• Create a new conda env

conda create --name dsp python=3.8
conda activate dsp

• Install PyTorch according to your CUDA version. For RTX 30 series, we recommend CUDA >= 11.1, PyTorch >= 1.8.0.

conda install pytorch==1.10.1 torchvision==0.11.2 torchaudio==0.10.1 cudatoolkit=11.3 -c pytorch -c conda-forge

• Install Argoverse API, please follow this page.

• Install other dependencies

pip install scikit-image IPython tqdm ipdb tensorboard

• Install PyTorch Scatter, please refer to this page.

Play with pretrained models

Generate a subset of the dataset for testing using the script (it will generate 1k samples):

bash scripts/argo_preproc_small.sh

Download the pretrained model (Google) (Baidu, code: cemi). Move the pretrained model to ./saved_models/, then use the scripts below to get prediction results:

bash scripts/argo_dsp_vis.sh

Since we store each sequence as a single file, the system may raise error OSError: [Erron 24] Too many open files during evaluation and training. You may use the command below to solve this issue:

ulimit -SHn 51200
ulimit -s unlimited

Train from scratch

• Preprocess Argoverse motion forecasting dataset using the script:

bash scripts/argo_preproc_all.sh

Note that the preprocessed dataset is pretty large (~ 90 GB), please reserve enough space for preprocessing.

• Launch (single-card) training using the script:

bash scripts/argo_dsp_train.sh
