# verinfo(3)

mlpack version information

## NAME

verinfo - mlpack version information

## mlpack versions in code

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_PATCH
```

In addition, the function **mlpack::util::GetVersion() returns the mlpack version as a string (for instance, 'mlpack 1.0.10').**

## mlpack executable versions

**Each mlpack executable 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 svn trunk, the version will be 'mlpack trunk' (and may have a revision number appended to 'trunk').**
