[aliysefian]

if graph_labels is not None:
on line 150 must be self.graph_labels
and in train

  batch_data, batch_labels = self.g2v.generate_file_batch(self.batch_size, self.window_size, self.doc_id,
                                                                    self.ROOT + self.dataset + '_corpus{}/{}'.format(label_suffix, self.corpus_fn_name.format(self.doc_id)),
                                                                    self.nodes_per_graphs[self.doc_id])

line 266

must add self
after I fix it I don't understand that
why self.nodes_per_graphs[self.doc_id]
can't find index 69 why?
