That's the same issue I had ~2 weeks ago - you are using driver 180.51, but
CUDA 2.2 requires 185.18.08. *
cuMemHostAlloc is one of the additional symbols used by CUDA 2.2 (and
therefore pyCuda expects it)
So the solution seems either to stick to CUDA 2.1, or install the nvidia
driver recommended for CUDA 2.2
