A python util to fetch datasets from different databases.

Currently supported databases are:

• LIBSVM (libsvm)

Getting design matrix and target variable is as easy as:

from libsvmdata import fetch_dataset
X, y = fetch_dataset("news20.binary")

Currently supported datasets are in libsvmdata.supported and can be displayed as:

from libsvmdata import print_supported_datasets
print_supported_datasets()

There is no need to specify the database name.

Files are saved under DATA_HOME/<database_name>, where the value of DATA_HOME is:

• the environment variable LIBSVMDATA_HOME if it exists,
• else, the environment variable XDG_DATA_HOME if it exists,
• else, $HOME/data.
