Hello,

could you add the recipe for the GPU version?

Hi @pidefrem, is there a reason that you closed this issue?
I was also looking for a GPU version of lightgbm on conda-forge.

now,does it support GPU? I am so confused that there are many channels to install lightgbm, and I am hard to find out wheather it is a gpu version. bad!
