mlpack provides a couple of convenience macros and functions to get the version
of mlpack. More information (and straightforward code) can be found in
src/mlpack/core/util/version.hpp.
The following three macros provide major, minor, and patch versions of mlpack
(i.e. for mlpack-x.y.z, x is the major version, y is the minor version,
and z is the patch version):
MLPACK_VERSION_MAJOR
MLPACK_VERSION_MINOR
MLPACK_VERSION_PATCHIn addition, the function mlpack::util::GetVersion() returns the mlpack
version as a string (for instance, "mlpack 1.0.8").
Each mlpack command-line program supports the --version (or -V) option,
which will print the version of mlpack used. If the version is not an official
release but instead from git, the version will be mlpack git (and will have a
git revision SHA appended to git).
