golinear is a package for training and using linear classifiers in the Go programming language (golang).


To use this package, you need the liblinear library. On Mac OS X, you can install this library with Homebrew:

brew install liblinear

Ubuntu and Debian provide packages for liblinear. However, at the time of writing (July 2, 2014), these were serverly outdated. This package requires version 1.9 or later.

This latest API-stable version (v1) can be installed with the go command:

go get

or included in your source code:

import ""

The package documentation is available at:


If you wish to use liblinear with OpenMP support for multicore processing, please use this command to install the package:



  1. Port classification to Go.
  2. Port training to Go.

We will take a pragmatic approach to porting code to Go: if the performance penalty is minor, ported code will flow to the main branch. Otherwise, we will keep it around until the performance is good enough.
