Recommended Hardware or Adjust Parameter for low end GPU

[Engrish]

I'm running into a CUDA out of memory error. Currently, I'm using i3-6100 with 16GB of memory and a Nvidia GTX 750 that only has 1GB of memory. Is there a way to adjust the parameter for low end GPU? If not, what's the minimum memory required for the GPU?

At least 4GB of gpu memory is required.
GTX 750 is not support, you can run it without gpu.

Thanks for the update. I did try using CPU only but it took a week so I was hoping CUDA would be faster. Please kindly update the readme to include the min. 4GB requirement.
