Tokenizer not found

when I try to use patrickvonplaten/longformer-random-tiny model and download the tokenizer, I get this error:

OSError: Model name ‘patrickvonplaten/longformer-random-tiny’ was not found in tokenizers model name list

There is the same problem on patrickvonplaten/reformer-tiny-random

But the model can be downloaded, and only the tokenizer was not found.
