NLTK WordNet錯誤，使用synsets查找單詞

我正在使用Python 3.6和NLTK 3.2.3，並且我僅爲「escort」一詞獲得「WordNetError」。我不會用任何其他詞語獲得錯誤。下面是顯示使用單詞「護送」與「狗」字和錯誤的成功成績單：NLTK WordNet錯誤，使用synsets查找單詞

During handling of the above exception, another exception occurred:

然而，當我在http://wordnetweb.princeton.edu/perl/webwn使用在線WordNet的搜索工具，它執行按預期的方式查找。最新的WordNet語料庫使用nltk.download（）下載。

該錯誤似乎引用WordNet定義中的一個十六進制值，當它期望找到一個整數值時。

任何想法？請告訴你是否遇到過這樣的事情。

仔細檢查「動詞」字典文件後，我發現它實際上已損壞。下面是一個像「vi」這樣的編輯器：

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 +

我用空格替換了「^ @」，問題就消失了。我想更大的問題是它如何在第一個地方被損壞。

問題解決！
