Hi, please note the line: CUDA backend: OFF which means that you did not build with CUDA support. Have a look at this to solve the problem.

I'm afraid the error cudaErrorUnknown: unknown error is due to something unrelated to gpufetch. It is likely that the problem is in your CUDA or drivers installation.
