Nvidia-smi : no devices were found

Hello, I am working on Ubuntu LTS 22.04 and have the Nvidia rtx3070 gpu on my laptop. I am working on training deep learning models and hence require CUDA support. Unfortunately, the nvidia-smi command on the terminal returns - " no devices were found". I have installed the gpu driver using the command, sudo ubuntu-drivers autoinstall. Attaching the screenshot of the available drivers, and also attaching the bug report. Any help to solve this issue will be greatly appreciated. Thank you.
