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a supported Ubuntu LTS distribution, and you're happy to install the respective tested CUDA versions (which often are outdated), by all means go ahead.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

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.

	#1. Calculate the proportion of variance explained by each feature
	sum_eigenvalues = np.sum(eigenvalues)

	prop_var = [i/sum_eigenvalues for i in eigenvalues]

	#2. Calculate the cumulative variance
	cum_var = [np.sum(prop_var[:i+1]) for i in range(len(prop_var))]

	# This script cleans all cache for Microsoft Teams on Linux
	# Tested on Ubuntu-like, Debian by @necrifede and Arch Linux by @lucas-dclrcq. Feel free to test/use in other distributions.
	# Tested with Teams via snap package.

	# How to use in terminal:
	# ./clear_cache_MS_Teams.sh ( deb-stable \| deb-insider \| snap )
	# or
	# bash clear_cache_MS_Teams.sh ( deb-stable \| deb-insider \| snap )
