Solution

  • I was having the same issue, I don't know what happen with the link but I found another one.

    You can look flair master repo https://github.com/flairNLP/flair/blob/master/flair/models/sequence_tagger_model.py on the def _fetch_model(model_name) line 971. There are using another path already "https://nlp.informatik.hu-berlin.de/resources/models", so they change to that path instead of alan-nlp.

    So you can find your model here https://nlp.informatik.hu-berlin.de/resources/models/ner/
