• Platform: MacOS X, Linux
• Python version: 3.7
• PyTorch version (GPU?): 1.6.0

Who can help

Information

Model I am using (Bert, XLNet ...): allegro/herbert-base-cased

I tried to use official script on model hub page with transformers version 3.5.1. Week ago it worked just fine, but now I am getting error listed below.
@rmroczkowski maybe you have some information on this topic, I saw some new commits on model hub, but they shouldn't change anything

For latest version it works fine with AutoTokenizers (EDIT: only version 4.4 works, I tasted version 3.5.1, 4.0.0, 4.3 and got same error)

The problem arises when using:

• the official example scripts: (give details below)
• my own modified scripts: (give details below)
  I tried importing AutoTokenizers and HerbertTokenizer, but got the same error
  `OSError: Can't load tokenizer for 'allegro/herbert-base-cased'. Make sure that:

• 'allegro/herbert-base-cased' is a correct model identifier listed on 'https://huggingface.co/models'

• or 'allegro/herbert-base-cased' is the correct path to a directory containing relevant tokenizer files`

The tasks I am working on is:

• an official GLUE/SQUaD task: (give the name)
• my own task or dataset: (give details below)

To reproduce

Steps to reproduce the behavior:

1. install transformers 3.5.1
2. try to use official script from https://huggingface.co/allegro/herbert-base-case

Expected behavior

tokenizer loads and works

I guess this is related to URL issue #10744 ? and one should change model URL

[Zhylkaaa]

I resolved this by updating URL's to models, this is my current code:

    "vocab_file": {"allegro/herbert-base-cased": "https://huggingface.co/allegro/herbert-base-cased/resolve/main/vocab.json"},
    "merges_file": {"allegro/herbert-base-cased": "https://huggingface.co/allegro/herbert-base-cased/resolve/main/merges.txt"},
}``` 
Is there a way to fix this to maintain backward compatibility? @LysandreJik
