Evaluation library is the fastest way for inference a model CatBoost. The library provides a C API.
The C API interface can be accessed from any programming language (example Golang + Cgo).
Prebuilt shared library (*.so | *.dylib) artifacts are available of the releases page on GitHub CatBoost project.
The shared library:
- Should be in
/usr/local/lib - Or set path in environment
CATBOOST_LIBRARY_PATH - Or set path manual in source code
SetSharedLibraryPath(see example below)
