AttributeError：'spacy.pipeline.ner.EntityRecognizer'对象没有属性'add_pipe'

Question

为什么下面的代码会抛出

add_pipe

属性未定义的错误？

if 'ner' not in nlp.pipe_names:
    ner = nlp.create_pipe('ner')
    ner.add_pipe(ner , last = True)
    for _, annotation in train_data:
      for ent in annotation['entities']:
        ner.add_label(ent[2])

Answer 1

要将管道组件添加到 spacy，您必须将它们添加到加载的模型 (

nlp

)，而不是单个组件（如

ner

）。

if 'ner' not in nlp.pipe_names: 
    ner = nlp.create_pipe('ner') 
    nlp.add_pipe(ner, last = True)  # replaced ner by nlp here
    for _, annotation in train_data: 
        for ent in annotation['entities']: 
            ner.add_label(ent[2])
