python - babelize_shell() 在 NLTK 包中不起作用

Question

我正在使用 python 进行 NLP，我发现了以下错误:

babelize_shell()
NLTK Babelizer: type 'help' for a list of commands.
Babel> how long before the next flight to Alice Springs?
Babel> german
Babel> run
0> how long before the next flight to Alice Springs?
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/nltk/misc/babelfish.py", line 175, in babelize_shell
    for count, new_phrase in enumerate(babelize(phrase, 'english', language)):
  File "/usr/local/lib/python2.7/dist-packages/nltk/misc/babelfish.py", line 126, in babelize
    phrase = translate(phrase, next, flip[next])
  File "/usr/local/lib/python2.7/dist-packages/nltk/misc/babelfish.py", line 106, in translate
    if not match: raise BabelfishChangedError("Can't recognize translated string.")
nltk.misc.babelfish.BabelfishChangedError: Can't recognize translated string.

如前所述，我已经导入了 nltk.book:

from nltk.book import*

*** NLTK 书籍的介绍性示例 ***

Loading text1, ..., text9 and sent1, ..., sent9

Type the name of the text or sentence to view it.

Type: 'texts()' or 'sents()' to list the materials.

text1: Moby Dick by Herman Melville 1851

text2: Sense and Sensibility by Jane Austen 1811

text3: The Book of Genesis

text4: Inaugural Address Corpus

text5: Chat Corpus

text6: Monty Python and the Holy Grail

text7: Wall Street Journal

text8: Personals Corpus

text9: The Man Who Was Thursday by G . K . Chesterton 1908

谁能帮帮我。我是 Python 的新手，不知道错误到底是什么。

Answer 1

问题不在于您的代码。问题是 babelfish 翻译服务不再运行，因此示例代码不再有效。
