Build Status

This is the vowpal wabbit fast online learning code. For Windows, look at README.windows.txt

You can download the latest version from here: https://github.com/JohnLangford/vowpal_wabbit/wiki/Download

Alternatively, the very latest version is available here:

git clone git://github.com/JohnLangford/vowpal_wabbit.git

You should be able to build it on most systems with: make (make test)

If that fails, try:

./autogen.sh
./configure
make
(make test)
make install

Note that ./autogen.sh requires automake. On OSX, this implies installing 'glibtools'

Be sure to read the wiki: https://github.com/JohnLangford/vowpal_wabbit/wiki for the tutorial, command line options, etc.

The 'cluster' directory has it's own documentation for cluster parallel use, and the examples at the end of test/Runtests give some example flags.

Something went wrong with that request. Please try again.
