I installed CUDA 8.0 to test it, now I tried to install back a higher version but NVIDIA assigned and installed again CUDA 8.0. I don’t know why or how I had CUDA 9.1 installed since it shouldn’t support Fermi GPUs.
julia> CUDA.version()
┌ Warning: CUDA.jl only supports NVIDIA drivers for CUDA 9.0 or higher (yours is for CUDA 8.0.0)
└ @ CUDA C:\Users\Martin Cornejo\.julia\packages\CUDA\5t6R9\src\initialization.jl:109
ERROR: Could not find a suitable CUDA installation
I should have tried this before changing the drivers…
