Describe the problem

I am facing two problems

1. While saving the BiLSTM-CRF model, the weights and the preprocessor files are being saved but not the params file.
2. While testing, I am getting the error "AttributeError: type object 'BiLSTMCRF' has no attribute 'load'"

Source code / logs

from anago.tagger import Tagger
from anago.models import BiLSTMCRF
from anago.preprocessing import IndexTransformer
from pprint import pprint


def main():
    print('loading objects')
    model = BiLSTMCRF.load("weights.h5", "params.json")
    it = IndexTransformer.load("preprocessor.json")
    tagger = Tagger(model, preprocessor=it)

    print('tagging a sentence')
    res = tagger.analyze("EU rejects German call to boycott British lamb .")
    pprint(res)

if __name__ == main():
    main()

ERROR

I'm running into the same error. I use Python 3.6 BTW.

You may have to use load_model:
from anago.models import load_model

Otherwise, you could use (for sequence models):
model = anago.Sequence.load(...)
