我正在使用Python 3.6和NLTK 3.2.3，并且我只收到"护送"一词的"WordNetError"。 我没有收到任何其他单词的错误。 以下是显示"狗"一词的成功和使用"护送"一词的错误：

但是，当我在 http://wordnetweb.princeton.edu/perl/webwn 使用在线 WordNet 搜索工具时，它会按预期执行查找。 最新的 WordNet 语料库是使用 nltk.download(( 下载的。
该错误似乎在期望找到整数值时引用了单词的 WordNet 定义中的十六进制值。
有什么想法吗？ 如果您遇到过这样的事情，请告知。
在仔细检查"动词"字典文件后，我发现它实际上已损坏。下面是它在像"vi"这样的编辑器中的样子：
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最初是如何被破坏的。
问题解决了！
