Playing the cuda version of leela chess zero on lenovo flex 14' with NVidia GeForce 840

I thought my laptop was not supported by CUDA version of Leela Chess Zero, the AI powered open source chess engine. But today, I have managed to run it on my old lenovo laptop.

Before this cuda build, i have been using the cpu version, opencl build and the last the directx 12 build. 

To run this, first i download the latest lc0 from lc0 download page. Then, I update my NVidia GeForce driver to the latest release. Unpack the cuda build of leela chess zero and add the engine to my Arena Chess GUI. And it work out of the box.
