python chatterbot [nltk_data] Error loading stopwords: ＜urlopen error [Errno 11004]_[nltk_data] error loading averaged_perceptron_tagg

运行项目出现如下错误：

[nltk_data] Error loading stopwords: <urlopen error [Errno 11004]
[nltk_data]     getaddrinfo failed>
[nltk_data] Error loading averaged_perceptron_tagger: <urlopen error
[nltk_data]     [Errno 11004] getaddrinfo failed>

解决方法如下：

前往地址：https://github.com/nltk/nltk_data

进入目录/packages/corpora/找到对应的文件stopwords.zip放到对应的文件之下

推荐整个nltk_data项目都下载695M大小，避免了其他问题无法下载的情况！

提取压缩文件

nltk_data-gh-pages.zip\nltk_data-gh-pages\packages

所有文件到以下目录中

C:\Users\Administrator\AppData\Roaming\nltk_data

这里每个人安装的目录可能会不一样，我这里是上面的目录，

修改对应文件：

当前项目目录下\venv\Lib\site-packages\chatterbot\utils.py

（有些童鞋的目录可能不在当前项目之下，可根据自己的配置找到对应的site-packages目录然后找到对应的文件进行修改）

需修改对应代码nltk_download_corpus('xxx')如下：

 
def download_nltk_stopwords():
    """
    Download required NLTK stopwords corpus if it has not already been downloaded.
    """
    nltk_download_corpus('corpora/stopwords')
 
 
def download_nltk_wordnet():
    """
    Download required NLTK corpora if they have not already been downloaded.
    """
    nltk_download_corpus('corpora/wordnet')
 
 
def download_nltk_averaged_perceptron_tagger():
    """
    Download the NLTK averaged perceptron tagger that is required for this algorithm
    to run only if the corpora has not already been downloaded.
    """
    nltk_download_corpus('taggers/averaged_perceptron_tagger')
 
 
def download_nltk_vader_lexicon():
    """
    Download the NLTK vader lexicon for sentiment analysis
    that is required for this algorithm to run.
    """
    nltk_download_corpus('sentiment/vader_lexicon')

愿你顺利解决问题
