Error when running example from README: Invalid URL 'ner-fast'

[flackbash]

I installed REL using pip and when running the minimal example from the README, I'm getting the following error:

I have flair version 0.11.3 installed.

Any idea what might be the problem?

Thanks in advance!

Could you try this instead?

tagger_ner = load_flair_ner("flair/ner-english-fast")

Thank you for the quick reply!

I just tried this, but I get the same error (Invalid URL 'flair/ner-english-fast').
The same happens for just ner-english-fast.

It seems like the problem is only with flair version 0.11.x.
I just upgraded flair from 0.11.3 to 0.12.2 and the original code runs again without issues.
