Pytorch Geometric Loader

Pytorch Geometric (>=2.2.0) provides an easy-to-use dataset loader for DGraphFin. Below is an example in Pytorch Geometric with only a few lines of code to load DGraphFin and get the train/valid/test mask.

import torch_geometric

# check your torch_geometric version and make sure it is not lower than 2.2.0
print(torch_geometric.__version__)
>>> '2.2.0'

# Please download DGraphFin dataset file 'DGraphFin.zip' on our website 'https://dgraph.xinye.com' and place it under directory './dataset/raw'
# Otherwise an error would pop out "Dataset not found. Please download 'DGraphFin.zip' from 'https://dgraph.xinye.com' and move it to './raw' "
from torch_geometric.datasets import DGraphFin

dataset = DGraphFin(root='./dataset')
data = dataset[0]

data
>>> Data(x=[3700550, 17], edge_index=[2, 4300999], y=[3700550], edge_type=[4300999], edge_time=[4300999], train_mask=[3700550], val_mask=[3700550], test_mask=[3700550])

Note: Please download DGraphFin dataset file 'DGraphFin.zip' on our website 'https://dgraph.xinye.com' and place it under directory './dataset/raw' before running the example, otherwise an error would pop out "Dataset not found. Please download 'DGraphFin.zip' from 'https://dgraph.xinye.com' and move it to './raw' "

Baselines

This repo provides a collection of baselines of DGraphFin. Please download the dataset file on our website and place it under the folder './dataset/DGraphFin/raw'.
