LightGBM.Net

.Net wrapper for LightGBM

Package	NuGet
LightGBMNet.Train
LightGBMNet.Tree

• Native LightGBM binaries in NuGet package are compiled for Intel/AMD 64 bit processors with Visual Studio 2022 (requires corresponding Visual C++ 2022 redistributable package to be installed).
• Training generates both a simple wrapper around the native LightGBM ensemble, and a corresponding 100% managed tree ensemble implementation.
• Managed implementation is fully self-contained in LightGBMNet.Tree (a .NET 6 assembly), with rigorous unit testing to ensure native and managed models generate identical outputs.
• See training unit tests for usage examples.
• GPU support:
  • Compile native LightGBM DLL/EXE files for your GPU configuration as per the instructions here.
  • Copy the native LightGBM files with GPU support over the CPU only versions in the native directory (or over those found in the build\x64 directory of the NuGet package)
  • Set DeviceType parameter to GPU.
