[SSL: CERTIFICATE_VERIFY_FAILED]

When running

import torch_geometric.transforms as T
from ogb.nodeproppred import PygNodePropPredDataset

dataset_name = 'ogbn-arxiv'
# Load the dataset and transform it to sparse tensor
dataset = PygNodePropPredDataset(name=dataset_name,
                                 transform=T.ToSparseTensor())
print('The {} dataset has {} graph'.format(dataset_name, len(dataset)))

I received the following question:

ogbn-arxiv has been updated.
Will you update the dataset now? (y/N)

then i sent y and received the following error:

SSLCertVerificationError                  Traceback (most recent call last)

During handling of the above exception, another exception occurred:

Hi @weihua916 , I tried other datasets and got the same error.

[zyzisastudyreallyhardguy]

Same here

[weihua916]

This indeed seems to be an issue. It is related our server. We will check and get back to you.

[weihua916]

I have just released ogb=1.2.6. Downloading should work now. Please update your package, and let me know if it works. Thanks!

[zyzisastudyreallyhardguy]

it works now thx!

[weihua916]

Awesome! Closing the issue.
