【问题描述】:
我将 Python 3.6 与 NLTK 3.2.3 一起使用,并且仅针对“escort”一词收到“WordNetError”。我没有得到任何其他词的错误。这是使用“狗”一词显示成功和使用“护送”一词的错误的成绩单:
Python 3.6.0 |Anaconda custom (64-bit)| (default, Dec 23 2016, 12:22:00)

>>> from nltk.corpus import wordnet

但是,当我使用http://wordnetweb.princeton.edu/perl/webwn 的在线 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。
当它期望找到一个整数值时,该错误似乎在 WordNet 定义中引用了一个十六进制值。
有什么想法吗?请告知您是否遇到过这样的事情。

当我从几个线程中使用 python wordnet 时,我得到了这些异常。那里的某些东西不是线程安全的。
