How to use gpu with C_API?

[n4sbsxp]

For some personal reason I need to run the code in c++ but I didn't found any function showing how to change the device in the document. https://lightgbm.readthedocs.io/en/latest/C-API.html

nah, you can try rewritting the code with cuda and recompile it.

How are you using the C API? If you're using for example LGBM_BoosterCreate you can specify device="gpu" in the parameters.

Hi @jameslamb ,

I'm not sure how @n4sbsxp is doing it.

I'm have been using 'device=gpu', but I'm blocked by #6220

Best
