Installing NLTK
|
|
===============
|
|
|
|
NLTK requires Python versions 3.5, 3.6, or 3.7
|
|
|
|
For Windows users, it is strongly recommended that you go through this guide to install Python 3 successfully https://docs.python-guide.org/starting/install3/win/#install3-windows
|
|
|
|
Setting up a Python Environment (Mac/Unix/Windows)
|
|
--------
|
|
|
|
Please go through this guide to learn how to manage your virtual environment managers before you install NLTK, https://docs.python-guide.org/dev/virtualenvs/
|
|
|
|
Alternatively, you can use the Anaconda distribution installer that comes "batteries included" https://www.anaconda.com/distribution/
|
|
|
|
Mac/Unix
|
|
--------
|
|
|
|
#. Install NLTK: run ``pip install --user -U nltk``
|
|
#. Install Numpy (optional): run ``pip install --user -U numpy``
|
|
#. Test installation: run ``python`` then type ``import nltk``
|
|
|
|
For older versions of Python it might be necessary to install setuptools (see http://pypi.python.org/pypi/setuptools) and to install pip (``sudo easy_install pip``).
|
|
|
|
Windows
|
|
-------
|
|
|
|
These instructions assume that you do not already have Python installed on your machine.
|

|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
#. Install Python 3.7: http://www.python.org/downloads/ (avoid the 64-bit versions)
|
|
#. Install Numpy (optional): https://www.scipy.org/scipylib/download.html
|
|
#. Install NLTK: http://pypi.python.org/pypi/nltk

Installing Third-Party Software
|
|
-------------------------------
|
|
|
|
Please see: https://github.com/nltk/nltk/wiki/Installing-Third-Party-Software
|
|
|
|
|
|
Installing NLTK Data
|
|
-------------------------------
|
|
|
|
After installing the NLTK package, please do install the necessary datasets/models for specific functions to work.
|
|
|
|
If you're unsure of which datasets/models you'll need, you can install the "popular" subset of NLTK data, on the command line type `python -m nltk.downloader popular`, or in the Python interpreter `import nltk; nltk.download('popular')`
