title: Why I can't download and use OGB (Open Graph Benchmark)?
body: <p>update: This code can just cause the perpetual running. Even if I don't  add any other code ?</p>
  <pre><code>from ogb.nodeproppred import PygNodePropPredDataset 
  </code></pre>
  <hr />
  <p>Here is my code, and I want to download the OGB.</p>
  <pre><code>import torch_geometric.transforms as T
  from ogb.nodeproppred import PygNodePropPredDataset
  
  
  dataset_name = 'ogbn-arxiv'
  
  dataset = PygNodePropPredDataset(name=dataset_name,
                                   transform=T.ToSparseTensor())
  print('The {} dataset has {} graph'.format(dataset_name, len(dataset)))
  
  # Extract the graph
  data = dataset[0]
  print(data)
  </code></pre>
  <p>But when I run this code, it just keep the state of running and output nothing.</p>
  <p>I think I've already match the requirement which shows in OGB website.</p>
  <p>I use windows11 and pycharm.</p>
