NameError：未定义名称“ wordnet”

如何解决NameError：未定义名称“ wordnet”

我正在尝试运行这段代码以实现基于同义词的文本扩充。

import nlpaug.augmenter.char as nac
import nlpaug.augmenter.word as naw
import nlpaug.augmenter.sentence as nas
import nlpaug.flow as nafc

from nlpaug.util import Action

text = 'The quick brown fox jumps over the lazy dog .'

aug = naw.SynonymAug(aug_src='wordnet')
augmented_text = aug.augment(text)

获取此异常

NameError: name 'wordnet' is not defined

我已经安装了nltk，并下载了wordnet，但出现了相同的错误。

解决方法

重启你的内核。

假设您像我一样在 jupyter notebook 上运行，但缺少 nltk 软件包并使用 !pip install nltk 将其安装在内核上，您必须重新启动内核才能使其工作。
