Python code
```python
    model_name="Vamsi/T5_Paraphrase_Paws"
    AutoTokenizer.from_pretrained(model_name)
    print(f"1 Loading model {str(model_name)}")
    AutoModelForSeq2SeqLM.from_pretrained(model_name)
    print(f"2 Loading model {str(model_name)}")    

```     





### Expected behavior

```shell
Good evening, sorry, I'm new working with Huggingface library.
I'm having an issue deploying a Flask application that I've deployed in Python.
It gets stuck at AutoModelForSeq2SeqLM.from_pretrained(model_name) and the loading process last forever.
I'm not sure if I've committed any mistake and this is not a bug so in case please notifiy me.
Thank you so much.
```

I am experiencing the same problem with the .from_pretrained calls. For me the temporary solution was to use a VPN, but of course it isn't fun. I was wondering why we need internet connection at all, since after the first call the data should be cached locally. Maybe add a flag in the call to explicitly run offline only?<|||||>In case of connection issues, you can try the [offline mode](https://huggingface.co/docs/transformers/v4.19.2/en/installation#offline-mode).<|||||>Could you share a bit regarding your location/network? Do you mange to download files when going through the UI on the hub?<|||||>> In case of connection issues, you can try the [offline mode]

Thanks! This is what I was looking for!

On my side, I am connecting through the VPN of my org. VPN location is chosen automatically, but when I turn it off the code execution of the .from_pretrained(..) is normal, whereas in the last days with VPN on it takes maybe 15 minutes. Before there were no issues with this. I am capable of downloading without issues the files from the hub directly.

Thanks for your time!
