Attributeerror: 'freqdist' Object Has No Attribute 'inc'

I am a beginner in Python and NLTK. I am trying to run the following code from a tutorial: from nltk.corpus import gutenberg from nltk import FreqDist fd = FreqDist() for word in

Solution 1:

You should do it like so:

fd[word] += 1

But usually FreqDist is used like this:

fd = FreqDist(my_text)

Also look at the examples here:

http://www.nltk.org/book/ch01.html

Solution 2:

For people looking for how to change the book example to NLTK 3.0:

import nltk
from nltk.corpus import brown

suffix_fdist = nltk.FreqDist()
for word in brown.words():
    word = word.lower()
    suffix_fdist[word[-1:]] +=1
    suffix_fdist[word[-2:]] +=1
    suffix_fdist[word[-3:]] +=1
common_suffixes = []
for suffix in suffix_fdist.most_common(100):
    common_suffixes.append(str(suffix.__getitem__(0)))
print common_suffixes

Solution 3:

Some of the features have been deprecated.

The code in question does work on version nltk 2.0.4

https://pypi.python.org/pypi/nltk/2.0.4

To install version 2.0.4 follow:

wget https://pypi.python.org/packages/source/n/nltk/nltk-2.0.4.zip#md5=cbd04d8635f1358a69a38c4774be029c

7z x nltk-2.0.4.zip

cd nltk-2.0.4/

python setup.py install

To check which version is installed run the following:

pip search nltk

Solution 4:

Latest version of nltk doesn't have inc. Rather I used update.

from nltk.corpusimport gutenberg
from nltk importFreqDist

fd = FreqDist()

for word in gutenberg.words('austen-sense.txt'):
    fd.update([word])

The update takes iterable item. So make sure you are passing iterable item in update function.
