Tagged Model Version Not Working
I am trying to download a specific version of the `roberta-large` model using the `revision` parameter of `from_pretrained()` as shown below:

```
from transformers import RobertaForSequenceClassification
model_type = "roberta-large"
v1 = "v3.5.0"
model = RobertaForSequenceClassification.from_pretrained(model_type, num_labels=2, revision=v1)
```

This code gives me the following 404 error:

```
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://huggingface.co/roberta-large/resolve/v3.5.0/config.json
```

Am I using the `revision` parameter incorrectly?

Extra notes:
- I am using transformers v4.1.1
- Running the same code above with `v1 = "main"` works just fine
I think you're using it wrong indeed. As said in the [docs](https://huggingface.co/transformers/model_sharing.html#model-versioning), you can either specify a tag name, branch name, or commit hash.<|||||>To reiterate over what @NielsRogge already said, this is the revision of the *model*, not the repository. You can check the model commits here: https://huggingface.co/roberta-large/commits/main

Revisions also include branches and tags, but this particular model only has a single branch and no tag.<|||||>Ah, that makes sense. Thanks for the prompt reply!
