python 2.7 - NLTK POS tagger not working

Question

If I try this :

import nltk
text = nltk.word_tokenize("And now for something completely different")
nltk.pos_tag(text)

Output:

Traceback (most recent call last):
File "C:/Python27/pos.py", line 3, in <module>
nltk.pos_tag(text)
File "C:Python27libsite-packages
ltk-2.0.4-py2.7.egg

tagger = load(_POS_TAGGER)

resource_val = pickle.load(_open(resource_url))
ImportError: No module named numpy.core.multiarray

Answer 1

It seems that the saved word tokenizer requires numpy. You'll need to install it.
