LightGBM Rust binding
You need an environment that can build LightGBM.
# linux
apt install -y cmake libclang-dev libc++-dev gcc-multilib
# OS X
brew install cmake libomp
On Windows
- Install CMake and VS Build Tools.
- Install LLVM and set an environment variable
LIBCLANG_PATHto PATH_TO_LLVM_BINARY (example:C:\Program Files\LLVM\bin)
Please see below for details.
Example LightGBM train.
extern crate serde_json;
use lightgbm::{Dataset, Booster};
use serde_json::json;
let data = vec![vec![1.0, 0.1, 0.2, 0.1],
vec![0.7, 0.4, 0.5, 0.1],
vec![0.9, 0.8, 0.5, 0.1],
vec![0.2, 0.2, 0.8, 0.7],
vec![0.1, 0.7, 1.0, 0.9]];
let label = vec![0.0, 0.0, 0.0, 1.0, 1.0];
let dataset = Dataset::from_mat(data, label).unwrap();
let params = json!{
{
"num_iterations": 3,
"objective": "binary",
"metric": "auc"
}
};
let bst = Booster::train(dataset, ¶ms).unwrap();
Please see the ./examples for details.
