python - SklearnClassifier' object has no attribute 'batch_classify'

Question

1.用分类器对开发测试集数据进行分类时，代码报错：SklearnClassifier' object has no attribute 'batch_classify'。

2.其中一段代码：

`def score(classifier):
    classifier = SklearnClassifier(classifier)
    classifier.train(train)
    pred = classifier.batch_classify(dev)
    return accuracy_score(tag_dev,pred)
print('BernoulliNB  accuracy is %f'%score(BernoulliNB()) )

3.报错：`

 File "G:/pycharm/全部.py", line 53, in <module>
    print('BernoulliNB  accuracy is %f'%score(BernoulliNB()) )
  File "G:/pycharm/全部.py", line 51, in score
    pred = classifier.batch_classify(dev)
AttributeError: 'SklearnClassifier' object has no attribute 'batch_classify'`

python3.5

Answer 1

题主描述写一下导入模块信息，不然不好判断啊。
或者把 classifier.batch_classify 改成 classifier.predict，因为sklearn中的接口基本是一致的
