NLTK import error

问题:

I'm new to Python and NLTK. I've been trying to find a solution to my problem but have not found one yet and was hoping someone could help me.

I'm currently running 64bit Windows 8. I've followed the instruction in the NLTK website (http://www.nltk.org/install.html). I might have installed a 64bit version Python in the first place but have removed it and reinstall 32bit version Python. Now I'm having the following problem:

Python 2.7.9 (default, Dec 10 2014, 12:24:55) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import nltk

Any ideas?

回答1:

I solve this by changing my operating system locale for non-Unicode programs:

1 – Go to Control Panel

2 – Click “Clock, Language and Region”

3 – Click “Regional and Language Options”

4 – Go under “Administrative” tab

5 – current system locale (for non-Unicode) is displayed, to change it click “Change system locale”

6 – Then just choose English! After a reboot, done!
