Issues with using nltk library

[Nikita Jain]

I have downloaded python 2.7.

Tried also installing nltk.

Now when I write code of import nltk, it shows me below:

>> import nltk

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "C:\Python27\lib\site-packages\nltk\__init__.py", line 99, in <module>

    from collocations import *

  File "C:\Python27\lib\site-packages\nltk\collocations.py", line 38, in <module>

    from nltk.metrics import ContingencyMeasures, BigramAssocMeasures, TrigramAssocMeasures

  File "C:\Python27\lib\site-packages\nltk\metrics\__init__.py", line 23, in <module>

    from nltk.metrics.segmentation    import windowdiff, ghd, pk

  File "C:\Python27\lib\site-packages\nltk\metrics\segmentation.py", line 44, in <module>

    import numpy

ImportError: No module named numpy

>>>

Please help.

Thank you,

If you look at the error, it’s about as clear as Python errors get: The nltk requires the module `numpy`, which you need to install separately. (In http://www.nltk.org/install.html it still says that numpy is “optional”, but that doesn’t seem to be the case; in any event lots of important things require numpy.)

Hi Nikita,

You could also try using the Anaconda Python Distribution. I guess “nltk” is a part of the distribution. Even if it isn’t, it might be easier to install with Anaconda.
