Is your feature request related to a problem? Please describe.

You may meet problems like:

requests.exceptions.SSLError: HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /junnyu/roformer_chinese_base/resolve/main/vocab.txt (Caused by SSLError(SSLCertVerificationError(1, "[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for 'huggingface.co'. (_ssl.c:1007)")))

Describe the solution you'd like

Setting proxy as below get rid of this problem.

import os
os.environ['HTTP_PROXY'] = 'http://proxy.company.com:port number>'
os.environ['HTTPS_PROXY'] = 'http://proxy.company.com:port number'

This setting also helps downloading models from Tensorflow Hub and PyTorch Hub, although the problems met on these sites are different from the one on Hugging Face.

Please be noted that the exact setting including the domain name and port number are highly likely different for your environment, provided you need to have a proxy server at first.
