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.

tmux HOWTO

tmux is a terminal multiplexer that lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal, and a lot more.

The tmux manpage (man tmux) or the printed copy of the tmux book near the team's library are great resources on using tmux.
This HOWTO just lists the most useful commands.
Despite tmux being a very powerful tool, the default configuration of tmux is not the most user friendly.
I am maintaining a tmux configuration file that makes life a bit easier here:

The HOWTO is written assuming this configuration file (or one with similar mappings) is installed.

Building TensorFlow from source (TF 2.3.0, Ubuntu 20.04)

Why build from source?

The official instructions on installing TensorFlow are here: https://www.tensorflow.org/install. If you want to install TensorFlow just using pip, you are running a supported Ubuntu LTS distribution, and you're happy to install the respective tested CUDA versions (which often are outdated), by all means go ahead. A good alternative may be to run a Docker image.

I am usually unhappy with installing what in effect are pre-built binaries. These binaries are often not compatible with the Ubuntu version I am running, the CUDA version that I have installed, and so on. Furthermore, they may be slower than binaries optimized for the target architecture, since certain instructions are not being used (e.g. AVX2, FMA).

So installing TensorFlow from source becomes a necessity. The official instructions on building TensorFlow from source are here: ht
