Flair and Pickle

[michaelgoeggelmann]

Question

Is it just me or is it not possible anymore to load tagged Sentence objects that have been stored in pickle files? If I do so, there's an TypeError: Span.__new__() missing 1 required positional argument: 'tokens' thrown. This hasn't been an issue in older flair versions.

Any workarounds? Thank you all!

edit: pos-tagged sentences actually work, I just tried. It seems to be specifically NER that causes the problem - maybe other models I haven't tried as well.

Hi @michaelgoeggelmann
I am sorry for responding so late.
I am not sure if the DataObjects were ever intendet to be saveable via pickle, but in generall I would recommend you to avoid pickle whenever possible.

Depending on your usecase, you could use sentence.to_dict() to get a json-serializable dict and save that one instead.
