Hi Phyllis,

My computer is equipped with a Nvidia GTX-750-Ti video card. It was one 
of the first two nvidia cards to use the Maxwell architecture. It 
includes 640 Cuda cores.

I use Linux Mint 18.3 Mate 64bit (which is built from a 16.04 kernel 
from Ubuntu). The nvidia 384.130 driver is installed.

I never installed anything particular for the Cuda cores and I don't 
know if I would be able to successfully install the CUDA Toolkit from 

But if I can be useful in testing your development, I'm ready to try.
