Tokenizer.from_pretrained calls stuck forever

Hi there,

when I call Tokenizer.from_pretrained it happens very often to me that the call gets stuck indefinetly, since the Huggingface web site isn’t repsonding. Today e.g. I could only get a tokenizer 3 times out of about 30 attempts.
Is there a way to force caching tokenizers such that I don’t need an internet connection on each call?
This gets really bad when I have projects and homeworks due.
