      I have now successfully untarred and ungzipped the package. Does anyone know what the next step is because when I attempted to run the distribute-setup.py i get an operation not allowed error. Any ideas?

        Have you tried going to nltk.org or better yet, do you have the book "Natural Language Processing with Python"? NLTK seems to work--- without running any setup scripts(though I have not tested it extensively)

            I didn't run the setup. I just tried the following

            import nltk
            nltk.download()
            

            And that allowed me to download the corpora.

                I used the version of shellista that includes the pdown command (not pipista). Then after unzipping and untaring, I moved everything to an nltk directory in Documents (within the Pythonista app). I was then able to import nltk and run samples from the book. I found it easier to move things around on the iPad using Diskaid from my Mac but you should be able to create the directories and move things from within Pythonista.

                  So u moved the entire nltk-2.0.4 folder to another folder named nltk and just opened up the console and run your commands?

                    @karthikmaiya, are you using the latest (1.5) version of pythonista? Do you have site-packages > nltk-2.0.4 > nltk or do you have site-packages > nltk or something else? I had to move things around a bit (using shellista). Just having the simple nltk right at the top level was the easiest way to get it working for me. I'm away from my iPad until tonight, so I can't look at all the details.

                      Yes i am on 1.5. My site-packages is separate from the folder nltk-2.0.4. So my nltk-2.0.4 folder is on the top level.

                        I have a folder nltk at the top level (same level as pipista.py). Within the nltk folder are all the files and folders that were inside the nltk-2.0.4 folder.

                          So how did u then import nltk. It still does not work for me. Did you have to run any setup scripts such as setuptools? And if so can you give me any specifics. I really want to start going through the book.

                            I haven't installed nltk, but for other toolboxes I've found that setup.py does not work.
                            Part of this is because the folder structure is different in pythonista than other environments. You don't have write access to ~ for example! you want to keep everything under ~/Documents.

                            Putting the folder under Site-packages is your best bet. Not sure, but you may need to restart pythonista to get it to reload that folder.
                            You can also os.chdir to your nltk folder (the one containing the actual nltk.py), and import from there.
                            You can also append to sys.path with the pointer to the folder containing nltk.py

                                    For example how can i set the NLTKDATA variable to the location of nltk_data

                                      I think I used pythonista to open the data.py file and set it by hand. I think I added it as a path in the list on line 66. Don't know if that is the proper way to do it, but I figured I might have to get a bit hacky to make it work on an iPad.

                                        Thats what I don't know though. Where am I setting it to? How do I find the path of nltk_data

                                          My nltk_data directory is at the same level as Documents and NLTK works without setting the NLTKDATA variable.

                                            Using the console I used

                                            import os
                                            print os.path.expanduser('~/')
                                            

                                            To get the path to the top level of my pythonista install. You can then add on whatever directories you have.
