Loading a SNAP dataset into torch_geometric.data.Data object

Question

I am trying to load a SNAP dataset (ego-facebook for now) into a torch_geometric.data.Data object. I am having issues.

1. Is there any standard library/method to load SNAP dataset into a torch_geometric.data.Data object?
2. I tried using torch_geometric.datasets.SNAPDataset. It gives me a storage of 10 Data. How can I merge the Data into one object so that I could generate one Networkx object?
3. I tried making the Data by adding each edge. Later, I wanted to use torch_geometric.transforms.RandomNodeSplit to generate the masks. But it did not add any mask. I figured RandomNodeSplit goes over data.node_stores. In this case, I didn't have any node_stores in my Data object. What is the correct way to make a Data object and add nodes/edges to it so that it is consistent with torch_geometric style?
