Can't get the dataset as the example indicates

[gkarozis]

I am trying to run the example of getting the 'rel-stackex' dataset, but an error occurs:

SSLError: HTTPSConnectionPool(host='relbench.stanford.edu', port=443): Max retries exceeded with url: /staging_data/rel-amazon-books_5_core/db.zip (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1131)')))

Could you please help me overcome this issue?

Thanks in advance!
