                  问题描述

                  尝试为 nltk 安装 Punkt 时出现以下错误:

                  I get the following error when trying to install Punkt for nltk:

                  nltk.download('punkt')    
                   [nltk_data] Error loading Punkt: <urlopen error [SSL:
                   [nltk_data]     CERTIFICATE_VERIFY_FAILED] certificate verify failed
                   [nltk_data]     (_ssl.c:590)>
                  False
                  

                  推荐答案

                  下载脚本坏了.作为临时解决方法,可以从 here 手动下载 punkt tokenizer,然后将解压缩的文件夹放在相应的位置.每个操作系统的默认文件夹是:

                  The downloader script is broken. As a temporal workaround can manually download the punkt tokenizer from here and then place the unzipped folder in the corresponding location. The default folders for each OS are:

                  • Windows:C: ltk_data okenizers
                  • OSX:/usr/local/share/nltk_data/tokenizers
                  • Unix:/usr/share/nltk_data/tokenizers
                  • Windows: C: ltk_data okenizers
                  • OSX: /usr/local/share/nltk_data/tokenizers
                  • Unix: /usr/share/nltk_data/tokenizers
