nltk - python33如何使用nltk3？

Question

我成功安装了 NLTK 2.0.4，但是当我尝试下载 NLTK 软件包时，即

nltk.download('stopwords')

它不起作用，所以我尝试安装适用于 python 3 的 NLTK 更新版本，但它给出了此错误:

>>> import nltk
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\Prashant\AppData\Roaming\Python\Python33\site-packages\nltk\_
nit__.py", line 37
    except IOError, ex:
              ^
SyntaxError: invalid syntax

有没有办法为python33安装NLTK？

Answer 1

首先安装python3-pip，然后用它来安装pyyaml

$ sudo apt-get install python3-pip
$ sudo pip3 install pyyaml
$ wget http://www.nltk.org/nltk3-alpha/nltk-3.0a3.tar.gz
$ tar -xzvf nltk-3.0a3.tar.gz
$ cd nltk-3.0a3/
$ sudo python3 setup.py install
$ python3
>>> import nltk
>>> from nltk.corpus import brown
>>> print(brown.sents()[0])
