In order to add a dataset into CogDL, you should know your dataset’s format. We have provided several graph format like edgelist, matlab_matrix and pyg. If the format of your dataset is the same as the ppi dataset, which contains two matrices: network and group, you can register your dataset directly use the following code.

class PPIDataset(MatlabMatrix):
    def __init__(self):
        dataset, filename = "ppi", "Homo_sapiens"
        url = ""
        path = osp.join("data", dataset)
        super(PPIDataset, self).__init__(path, filename, url)

You should declare the name of the dataset, the name of file and the url, where our script can download resource. More implemented datasets are at
