This is a fast and memory efficient loader (and writer...) for the svmlight / libsvm sparse data file format in Python.
To install for all users on Unix/Linux:
python setup.py build sudo python setup.py install
Same as scikit-learn (almost):

Public datasets in svmlight / libsvm format available at http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/
