chatterbot 每次启动执行 nltk_download_corpus
[nltk_data] Error loading stopwords: <urlopen error [Errno 60]
[nltk_data] Operation timed out>
[nltk_data] Error loading averaged_perceptron_tagger: <urlopen error
[nltk_data] [Errno 60] Operation timed out>
chatterbot里stopwords在nltk-data目录下、上述下载方式stopwords在nltk-data下的corpora目录
由于目录结构问题导致每次下载 stopwords、wordnet、averaged_perceptron_tagger、vader_lexicon
而网络问题导致各种timed out
修改文件 .pyenv/versions/3.7.4/lib/python3.7/site-packages/chatterbot/utils.py
