LightGBM4J

A JVM interface for LightGBM, written in Scala, for inference in production.

Hopefully makes it a littler easier to use LightGBM from Java/Scala compared to using the SWIG wrappers directly.

LightGBM4J:

• Provides a version of the native linux lib_lightgbm.so library compiled without OpenMP. This reduces latency when LightGBM is used to predict concurrently in a multi-threaded application (eg: a http server).
• Is self-contained. The native libraries are packaged together with this library, and loaded for you.
• Correctly handles marshalling and memory management between your application and native code
• Includes Mac OS X native libraries for local development

See the tests for example usage.

Versions

The LightGBM4J version uses the base LightGBM version with LightGBM4J release appended with a dash, e.g. 2.2.2-1 is the first LightGBM4J release based on LightGBM4J version 2.2.2.

Usage

make test run tests
make build-libs-linux build native libs for linux
make build-libs-mac build native libs for mac

Who's using this?

Used in production at SEEK.
