Question

您好我想使用名为textrank的以下包，请参阅以下网址了解详情：

https://github.com/davidadamojr/TextRank

在使用pip3克隆所有依赖项之后，我尝试使用此存储库，如下所示：

textrank extract_summary test

但是我收到以下错误：

MacBook-Pro:TextRank-master $ textrank extract_summary test 
Traceback (most recent call last):

似乎缺少nltk库的文件，所以我尝试了：

MacBook-Pro:TextRank-master adolfocamachogonzalez$ python3

但是我无法获得外部资源，因为我尝试将链接复制并粘贴到浏览器中，但我只是像xml结构一样，如下所示：

Answer 1

文件english.pickle是“punkt”标记器的一部分，它将文本分解为句子。要下载它，请运行以下一次（或在交互式下载器中的模型下找到“punkt”）。

nltk.download("punkt")

下载程序将检查可写入的位置的标准路径列表，并将模型文件保存在那里。之后，它将可用于textrank的内部。

如何使用TextRank克服以下问题？
