question

I trained a lightgbm model in python, and saved as a model file, then I want to predict new data in C++. I search in the web but cannot find a good example.

you can use the trained model files, with compiled lightgbm execute files (like exe) to run your prediciton. refer to https://github.com/Microsoft/LightGBM/tree/master/examples/binary_classification#prediction
