D2GNAS is an efficient graph neural architecture search method with decoupled differentiable search.
-
The framework of D2GNAS is as follows:
- Ensure you have installed CUDA 11.1 before installing other packages
1.Python environment: recommending using Conda package manager to install
conda create -n d2gnas python=3.7
source activate d2gnas
2.Python package:
torch == 1.8.2
torch-geometric == 2.0.2
torch-scatter == 2.0.7
torch-sparse == 0.6.11
hyperopt == 0.1.2
1.Performance test with manual GNN and the optimal GNN designed by D2GNAS
python performance_test.py
2.Search the top promising GNN architectures from scratch with all GNAS methods and test with HPO
step1:python search_from_scratch.py
step2:python performance_test_with_hpo.py
3.Unzip the cs_phy.tar.gz in the dataset file first for CS and Physics testing
tar -xvf cs_phy.tar.gz
