Open-sourced implementation for TNNLS 2023.

1. We propose a graph gradual pruning framework, namely CGP, to reduce the training and inference computing costs of GNN models while preserving their accuracy.

2. We comprehensively sparsify the elements of GNNs, including graph structures, the node feature dimension, and model parameters, to significantly improve the efficiency of GNN models.

3. Experimental results on various GNN models and datasets consistently validate the effectiveness and efficiency of our proposed CGP.

Our proposed CGP is implemented in Python 3.7 and major libraries include:

• Pytorch = 1.11.0+cu113
• PyG torch-geometric=2.2.0

More dependencies are provided in requirements.txt.

Once the requirements are fulfilled, use this command to run:

sh xx.sh

All datasets used in this paper can be downloaded from PyG.
