Solution: just download file directly and put it in folder ../.cache/torch/ checkpoints.

Not a solution, merely a workaround! This is a feature of the library that still isn't working properly. It's a bug. It should be fixed. For good.

This is not a bug in the library. The certificate is valid. Please check for example: https://stackoverflow.com/questions/27835619/urllib-and-ssl-certificate-verify-failed-error
