Installation Guide

For now, xLearn can support Linux and Mac OS X. We will support it on Windows platform in the near future. This page gives instructions on how to build and install the xLearn package using pip and how to build it from source code. No matter what way you choose, make sure that your OS has already installed GCC (or Clang) and CMake, and your compiler need to support C++11. If you have not installed them, please see this page on how to install GCC and CMake.

Install xLearn from pip

The easiest way to install xLearn Python package is to use pip. The following command will download the xLearn source code from pip and install Python package locally.

sudo pip install xlearn

The installation process will take a while to complete. And then you can type the following script in your python shell to check whether the xLearn has been installed successfully:

>>> import xlearn as xl
>>> xl.hello()

You will see:

      xLearn   -- 0.30 Version --

If you want to build the latest code from Github, or you want to use the xLearn command line instead of the Python API, you can see how to build xLearn from source code as follow. We highly recommend that you can build xLearn from source code.

Install xLearn from Source Code

Building xLearn from source code consists two steps.

First, you need to build the executable files (xlearn_train and xlearn_predict), as well as the shared library ( for Linux and libxlearn_api.dylib for Mac OSX) from the C++ code.

Then, you can install the Python package through

Fortunately, we write a script to do all the cumbersome work for users.

For users, you just need to clone the code from github

git clone

and then build xLearn using the folloing commands:

cd xlearn

You may be asked to input your password during installation.

Test Your Building

Now you can test your installation by using the following command:

cd build

You can also test the Python package by using the following command:

cd python-package/test
