Google App Engine import NLTK error

Question

I am trying to import NLTK library in Google App Engine it gives error, I created another module "testx.py" and this module works without error but I dont know why NLTK does not work.

My code nltk_test.py

import webapp2
import path_changer
import testx
import nltk

class MainPage(webapp2.RequestHandler):

    def get(self):
        #self.response.headers['Content-Type'] = 'text/plain'
        self.response.write("TEST")

class nltkTestPage(webapp2.RequestHandler):
    def get(self):
        text = nltk.word_tokenize("And now for something completely different")
        self.response.write(testx.test("Hellooooo"))


application = webapp2.WSGIApplication([
    ('/', MainPage), ('/nltk', nltkTestPage),
], debug=True)

testx.py code

def test(txt):
    return len(txt)

path_changer.py code

import os
import sys

sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'nltk'))
sys.path.insert(1, os.path.join(os.path.dirname(__file__), 'new'))

app.yaml

application: nltkforappengine
version: 0-1
runtime: python27
api_version: 1
threadsafe: true

handlers:

- url: /.*
  script: nltk_test.application
- url: /nltk.*
  script: nltk_test.application

libraries:
- name: numpy
  version: "1.6.1"

This code works fine When I comment the import nltk and nltk related code, I think NLTK is not imported, please help me to sort out this problem, thanks

Where do you have nltk installed?

GAE libraries need to be available in your app folder. If you have nltk elsewhere in your pythonpath it won't work.
