NameError: name 'wordnet' is not defined

Question

I'm trying to run this piece of code for synonym-based text augmentation.

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)

Getting this exception

I've installed nltk and downloaded wordnet but got same error.

Answer 1

Restart your kernel.

Assuming like me, you were running on a jupyter notebook, were missing the nltk package and installed it on kernel using !pip install nltk, you would have to restart kernel to make it work.
