Proxmox VM - nvidia-smi: No devices were found

Hello guys,

I’m actually trying to deploy a K8s cluster using Proxmox, I have followed the first step of this guide, I didn’t use the Window iso, but Ubuntu. My goal is to use GPU passthrough with my GTX 950M on my laptop. The VM has 4Go Mem, 2 Cpus and 32Go disk storage`. To install the dirvers needed I have followed this guide.

All went good but when i try to use nvidia-smi I got:

No devices were found
