NVIDIA GPU 0: cannot be selected

[sapmi]

Hi There, I' using Ubuntu 18.04' . This the the error I am getting. "NVIDIA GPU 0: cannot be selected"

libxmrig-cuda.so is in the same directory as xmrig. Here is my nvcc --version:

nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2021 NVIDIA Corporation Built on Sun_Feb_14_21:12:58_PST_2021 Cuda compilation tools, release 11.2, V11.2.152 Build cuda_11.2.r11.2/compiler.29618528_0

Here is my nvidia-smi:

What have I done wrong?

Update - I installed CUDA the wrong way. To correct I purged as much of my old install as possible, installed via deb network option, then rebuilt xmrig and xmrig cuda. It now works
