Error downloading some datasets

[aurorarossi]

Hello!
when downloading the datasets contained here, there is an error caused by the certificate of the website.

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1002)>

@aurorarossi , I also faced the same issue when downloading a dataset through a URL. You can solve this issue by using the SSL authentication module. You may solve it by adding the module and code below.

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

Looks like the SSL certificate for https://graphmining.ai/temporal_datasets/ which hosts some of the datasets has expired about a week ago.

I was wondering if it was maintained by the same people of this package

Judging by the homepage I'd say so. Let's see what they say :)

After two months, the certificates are still expired

This happens when using torch_geometric_temporal:
loader = METRLADatasetLoader()
Python 3.11.2, PyTorch 2.0.1
