在python中存储crf标记器

Question

crf_tagger = CRFTagger()
crf_tagger.train(train_sents,'/tmp/crf_tagger.model')
#Store CRFT.
from pickle import dump
output = open('crfTagger.pkl', 'wb')
dump(crf_tagger, output, -1)
output.close()

当我运行上面的部分时，得到：

TypeError: self.c_tagger cannot be converted to a Python object for pickling

如果我用另一个模型就可以了

Answer 1

Pickle无法转储Python对象。用莳萝代替泡菜：https://pypi.org/project/dill/
