I had many driver installed I my virtual machine , so It was actually the reason why I was having the error.

To fix it I had first to remove all driver I have installed before using :

• sudo apt-get purge nvidia-*
• sudo apt-get update -sudo apt-get autoremove

After that I when a head and installed the latest version of it nvidia driver:

I did :

Installing the NVIDIA driver, CUDA and cuDNN on Linux (Ubuntu 20.04)

This is a companion piece to my instructions on building TensorFlow from source. In particular, the aim is to install the following pieces of software

• NVIDIA graphics card driver (v450.57)
• CUDA (v11.0.2)
• cuDNN (v8.0.2.39)

on an Ubuntu Linux system, in particular Ubuntu 20.04.

To check nvidia driver

modinfo nvidia

To check cuda version

cat /usr/local/cuda/version.txt
