## What is fastText?
fastText is a library for efficient learning of word representations and sentence classification.
## Requirements
fastText builds on modern Mac OS and Linux distributions.
Since it uses C++11 features, it requires a compiler with good C++11 support.
These include :
* (gcc-4.6.3 or newer) or (clang-3.3 or newer)
Compilation is carried out using a Makefile, so you will need to have a working **make**.
For the word-similarity evaluation script you will need:
* python 2.6 or newer
* numpy & scipy
## Building fastText as a command line tool
In order to build `fastText`, use the following:
```bash
$ git clone https://github.com/facebookresearch/fastText.git
$ cd fastText
$ make
```
This will produce object files for all the classes as well as the main binary `fasttext`.
If you do not plan on using the default system-wide compiler, update the two macros defined at the beginning of the Makefile (CC and INCLUDES).
## Building `fasttext` python module
In order to build `fasttext` module for python, use the following:
```bash
$ git clone https://github.com/facebookresearch/fastText.git
$ cd fastText
$ sudo pip install .
$ # or :
$ sudo python setup.py install
```
Then verify the installation went well :
```bash
$ python
Python 2.7.15 |(default, May 1 2018, 18:37:05)
Type "help", "copyright", "credits" or "license" for more information.
>>> import fasttext
>>>
```
If you don't see any error message, the installation was successful.
