Install PyTorch following the instuctions on the [official website] (https://pytorch.org/). The code has been tested over PyTorch 1.1.0 versions.

Then install the other dependencies.

conda env create -f environment.yml

conda activate dpggan

pip install -r requirements.txt

Unzip the dataset file

unzip data.zip

and run

sh run.sh

Default parameters are not the best performing-hyper-parameters. Hyper-parameters need to be specified through the commandline arguments.

For graph classification experiment and link prediction experiment, please refer run_graph_classification_exp.sh and run_link_classification_exp.sh.
