How to use prefix ner tags with skweak aggregation.HMM

[javinator48]

Currently I am trying to apply aggregation.HMM on pretrained hugging face models on the wikineural dataset( https://huggingface.co/datasets/Babelscape/wikineural) and I have these tags ['O', 'B-PER', 'I-PER', 'B-ORG', 'I-ORG', 'B-LOC', 'I-LOC', 'B-MISC', 'I-MISC']. However I get an error RuntimeError: Initial labels should not have a prefix. How can I handle these type of tags?
