louvain clustering is not available to network model

[cbaakman]

I ran the following script, using Deeprank-GNN:

#!/usr/bin/env python

from deeprank_gnn.GraphGen import GraphHDF5
from deeprank_gnn.NeuralNet import NeuralNet
from deeprank_gnn.ginet import GINet
from deeprank_gnn import CustomizeGraph

preprocessed_path = "./preprocessed.hdf5"

GraphHDF5(pdb_path="./pdb", graph_type="residue", outfile=preprocessed_path)
CustomizeGraph.add_target(".", "bin_class", "targets.txt", sep=" ")

NN = NeuralNet(preprocessed_path, GINet,
               node_feature=['type', 'polarity', 'bsa', 'charge'],
               edge_feature=['dist'],
               target='bin_class',
               batch_size=1,
               cluster_nodes='louvain')

NN.train(nepoch=250, validate=False)

PDB files were: 1jyn.pdb 2y69.pdb 5ju6.pdb

The output was:

Switching to mcl clustering makes it work.

Is Louvain clustering available ?

Thanks for raising this issue.

Identified issue: when running Deeprank-GNN with the louvain node clustering algorithm, Deeprank-GNN was still expecting mcl cluster data due to a lack of specification of the clustering algorithm used when loading the data (in HDF5dataset)

Solution: Update every call of HDF5dataset with clustering information

HDF5DataSet(root='./', database=database, node_feature=self.node_feature, edge_feature=self.edge_feature,
                  target=self.target, clustering_method=self.cluster_nodes)

This has been solved in PR #59
