Code for "SGCN:Sparse Graph Convolution Network for Pedestrian Trajectory Prediction" CVPR 2021

SGCN

Code for SGCN:Sparse Graph Convolution Network for Pedestrian Trajectory Prediction (CVPR2021)

Paper

Environment

The code is trained and tested on RTX 2080Ti, Python 3.6.2, numpy 1.19.0, pytorch 1.2.0 and CUDA11.2.

SGCN

SGCN models the sparse graph in two aspects:

1. a Spatial Sparse Graph to represent sparse interaction
2. a Temprial Sparse Graph to represent diverse motion tendencies

framework

Sprarse Graph Learning

Train

To train a model on a single dataset, such as eth, you can run below code in root directory of this project:

python train.py --dataset eth

or training on each dataset:

sh train.sh

Test

To evaluate your trained model or our pretrain model you can run:

python test.py

Note that the pretrain model lies in 'checkpoints'.
