I'm trying to use
classifier = pipeline("zero-shot-classification", model='facebook/bart-large-mnli')

But I get this error:
OSError: We couldn't connect to 'https://huggingface.co' to load this file, couldn't find it in the cached files and it looks like facebook/bart-large-mnli is not the path to a directory containing a file named config.json.
Checkout your internet connection or see how to run the library in offline mode at 'https://huggingface.co/docs/transformers/installation#offline-mode'.

I tried to re-connect and change the internet connection, and also tried to run the codes on cloud based envrionments, but the same error message appeared.
