Macでpython3の環境構築8---NLTKのインストール2---
前回の続きです。
（前回:

nltk.download()とコマンドを打ってもうまくいかないというお話でした。
これは次のようなコマンドでも代替できるようです。
hiroshi-no-MacBook-Air:~ hiroshi$ python3 -m nltk.downloader book
# 「python3 -m nltk.downloader book」と打ってreturnを押す。
そうすると、次のような処理が始まります。

[nltk_data] Done downloading collection book
hiroshi-no-MacBook-Air:~ hiroshi$
では、次にそのまま、
hiroshi-no-MacBook-Air:~ hiroshi$ from nltk.book import *
# $のあとにいきなり「from nltk.book import *」と打ってもうまくはいかない。
としても。。。
from: can't read /var/mail/nltk.book
hiroshi-no-MacBook-Air:~ hiroshi$
と返されうまくいきません。
今度はこうしてみます。
hiroshi-no-MacBook-Air:~ hiroshi$ python3
そうすると、こうなります。
Python 3.4.3 (default, Aug 11 2015, 08:57:25)
[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>
また入力の待ち状態になるので、続けて二つコマンドを打ってみます。
>>> import nltk # 「import nltk」と打ってreturnを押す。
>>> text1 # 続けてtext1と打ってreturnを押す。
それでも、やはりこうなってしまい失敗。
Traceback (most recent call last):
File "", line 1, in
NameError: name 'text1' is not defined
>>>
今度は、こうしてみます。
>>> from nltk.book import * # 「from nltk.book import *」と打ってreturnを押す。
そうすると次のようになります。
*** Introductory Examples for the NLTK Book ***
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
>>>
最後に、「text1」と打って
>>> text1
<Text : Moby Dick by Herman Melvile 1851 >
>>>
となり、なんとか成功しました。
まとめとしては、「python3 -m nltk.downloader book」を行ったあとは
- python3 とコマンドを打つ。
- import nltk とコマンドを打つ。
- from nltk.book import * とコマンドを打つ。
- 最後にtext1と打って、上記のように表示されれば成功。
となります。
