NLTK WordNet错误，使用synsets查找单词

我正在使用Python 3.6和NLTK 3.2.3，并且我仅为“escort”一词获得“WordNetError”。我不会用任何其他词语获得错误。下面是显示使用单词“护送”与“狗”字和错误的成功成绩单：NLTK WordNet错误，使用synsets查找单词

During handling of the above exception, another exception occurred:

然而，当我在http://wordnetweb.princeton.edu/perl/webwn使用在线WordNet的搜索工具，它执行按预期的方式查找。最新的WordNet语料库使用nltk.download（）下载。

该错误似乎引用WordNet定义中的一个十六进制值，当它期望找到一个整数值时。

任何想法？请告诉你是否遇到过这样的事情。

仔细检查“动词”字典文件后，我发现它实际上已损坏。下面是一个像“vi”这样的编辑器：

02025829 38 v 01 escort 0 006 @ 02025550 v 0000 + 09992538 n 0102 ~ 02026203 v 0000 ~ 02026327 v 0000 ~ 02026433^@v 0000 ~ 02026712 v 0000 04 +

我用空格替换了“^ @”，问题就消失了。我想更大的问题是它如何在第一个地方被损坏。

问题解决！
