### Who can help
@LysandreJik 

## Information

Model I am using (Bert, XLNet ...): any model

The problem arises when using:
* [ ] the official example scripts: (give details below)
* [ x] my own modified scripts: (give details below)

## To reproduce

Steps to reproduce the behavior:

`tokenizer = transformers.AutoTokenizer.from_pretrained("bigscience/tr3m-1B3-pile-checkpoints", revision="global_step1500")`

An erroneous warning is displayed: `404 Client Error: Not Found for url: https://huggingface.co/bigscience/tr3m-1B3-pile-checkpoints/resolve/main/config.json`, hinting that the AutoTokenizer is looking in the wrong place (the master branch), ignoring the revision argument, and not finding the file. However, the tokenizer is correctly initialized.

## Expected behavior

No warning.
Seems to be working fine for me

logging.basicConfig(level=logging.DEBUG)
tokenizer = transformers.AutoTokenizer.from_pretrained("bigscience/tr3m-1B3-pile-checkpoints", revision="global_step1500")
