Cómo instalar TensorFlow en Ubuntu 20.04 | DigitalOcean

Introducción

TensorFlow, una biblioteca de software de aprendizaje automático de código abierto, se utiliza para entrenar redes neurales. Cada nodo, expresado en forma de gráficos de flujo de datos con estado, representa las operaciones realizadas por redes neurales en matrices multidimensionales. Estas matrices multidimensionales se denominan comúnmente “tensores”, de ahí el nombre de TensorFlow.

En este tutorial, instalará TensorFlow en un entorno virtual Python con virtualenv. Este enfoque aísla la instalación de TensorFlow y pone las cosas en funcionamiento rápidamente. Una vez que complete la instalación, la validará importando TensorFlow para garantizar que no tenga errores.

Requisitos previos

Antes de empezar este tutorial, necesitará lo siguiente:

• Un servidor de Ubuntu 20.04 con al menos 4 GB de RAM y configurado mediante la guía de configuración inicial para servidores de Ubuntu 20.04, con un usuario sudo no root y un firewall.
• Python 3.8 o superior y virtualenv instalados. Siga la guía Cómo instalar Python 3 en Ubuntu 20.04 para configurar Python y virtualenv.

Paso 1: Crear un entorno de programación

En este paso, crearemos un entorno virtual en el que instalar TensorFlow sin comprometer nuestros otros proyectos de programación. Si ya tiene un entorno de programación limpio, puede omitir este paso.

Primero, cree un directorio de proyecto. Lo llamaremos tf-demo a efectos de demostración, pero elija un nombre de directorio que le resulte significativo:

mkdir ~/tf-demo

Diríjase a su directorio tf-demo que creó recientemente:

cd ~/tf-demo

A continuación, cree un entorno virtual nuevo llamado tensorflow-dev, por ejemplo. Ejecute el siguiente comando para crear el entorno:

python3 -m venv tensorflow-dev

Esto crea un directorio nuevo tensorflow-dev que contendrá todos los paquetes que instale mientras esté activado este entorno. También incluye pip y una versión independiente de Python.

Ahora active su entorno virtual:

source tensorflow-dev/bin/activate

Una vez activado, su mensaje de terminal reflejará que está en el entorno virtual:

(tensorflow-dev)username@hostname:~/tf-demo $

En este punto, puede instalar TensorFlow en su entorno virtual.

How to Install TensorFlow on Ubuntu 20.04 | 18.04

This brief tutorial shows students and new users how to install TensorFlow on Ubuntu 20.04 | 18.04.

For those who don’t know, TensorFlow is an end-to-end open source platform for machine learning built by Google. It has a comprehensive libraries and community resources that allows anyone to build machine learning programs.

When it comes to installing TensorFlow, it can be installed system-wide, in a Python virtual environment, as a Docker container and other others. The most common way to install TensorFlow is via a Python virtual environment where multiple environments can be created and managed easily.

If you’re a student or new user looking for a Linux system to start learning on, the easiest place to start is Ubuntu Linux OS…. It’s a great Linux operating system for beginners and folks looking for easier Linux distribution to use.

Ubuntu is an open source Linux operating systems that runs on desktops, laptops, server and other devices.

When using Ubuntu, you will find that Linux isn’t so different than Windows and other operating systems in so many ways, especially when it comes to using the system to get work done.…

Both Ubuntu and Windows systems allow you to be productive, easy to use, reliable and enable you to install and run thousands of programs from gaming to productivity suite software for individuals and businesses.

To get started with installing TensorFlow, follow the steps below:

ScaleGrid DigitalOcean Support for MySQL, PostgreSQL and Redis™

PALO ALTO, Calif., June 9, 2020 – ScaleGrid, a leading Database-as-a-Service (DBaaS) provider, has just announced support for their MySQL, PostgreSQL and Redis™ solutions on DigitalOcean. This launch is in addition to their current DigitalOcean offering for MongoDB® database, the only DBaaS to support this database on DigitalOcean.

MySQL and PostgreSQL are the top two open source relational databases in the world, and Redis is the top key-value database. These databases are a natural fit for the developer market that has gravitated towards DigitalOcean since its launch just nine years ago in 2011. The open source model is not only popular with the developer market, but also enterprise companies looking to modernize their infrastructure and reduce spend.  DigitalOcean instance costs are also over 28% less expensive than AWS, and over 26% less than Azure, providing significant savings for companies who are struggling in this global climate.

ScaleGrid’s MySQL, PostgreSQL and Redis™ solutions on DigitalOcean are competitively priced starting at just $15/GB, the same as DigitalOcean’s Managed Database solution, but offer on average 30% more storage for the same price. Additionally, ScaleGrid offers several competitive advantages such as full superuser access, custom master-slave configurations, and advanced slow query analysis and monitoring capabilities through their sophisticated platform. To compare more features, check out their ScaleGrid vs. DigitalOcean MySQL, ScaleGrid vs. DigitalOcean PostgreSQL and ScaleGrid vs. DigitalOcean Redis™ pages.

Upgrade Ubuntu 20.04/20.10 to 21.04 in 2 Ways (GUI & Terminal)

Ubuntu 21.04, codenamed Hirsute Hippo, is released on April 22, 2021. This tutorial is going to you 2 ways to upgrade Ubuntu 20.04/Ubuntu 20.10 to 21.04. The first method uses the graphical update manager and the second method uses command line. Usually, you use the graphical update manager to upgrade Ubuntu desktop and use the command line to upgrade Ubuntu server, but the command-line method works for desktops too.

Ubuntu 20.04 is a long-term support (LTS) release, which will be supported for 5 years. Ubuntu 21.04 is a non-LTS release, which means it will be supported for 9 months only, until January 2022. If you prefer stability over bleeding edge, then stick with Ubuntu 20.04. But if you are the other way around, you can follow this tutorial to upgrade from Ubuntu 20.04 to 21.04.

How To Install Jenkins on Ubuntu 20.04 / Ubuntu 18.04

Jenkins is an open-source automation server that helps to automate the repetitive tasks involved in the software development process, which includes building, testing, and deployments.

Jenkins was forked from the Oracle Hudson project and written in Java.

Here, we will see how to install Jenkins on Ubuntu 20.04 / Ubuntu 18.04.

Install Jenkins On Ubuntu 20.04

Install Java

Since Jenkins is written in Java, it requires Java 8 or Java 11 to run. Here, I will install the OpenJDK 11 for Jenkins installation.

sudo apt update

sudo apt install -y default-jre apt-transport-https wget

If you want to use the Oracle Java in place of OpenJDK, then use any one of the links to install it.

READ: How To Install Oracle Java on Ubuntu 20.04

READ: How To Install Oracle Java on Ubuntu 18.04

Verify the Java version after the installation.

java -version

Output:

openjdk version "11.0.8" 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu120.04)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

Add Jenkins Repository

Jenkins provides an official repository for its packages. To use the Jenkins repository, first, we will need to add the Jenkins public key to the system.

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

Then, add the Jenkins repository to your system.

echo "deb https://pkg.jenkins.io/debian-stable binary/" | sudo tee /etc/apt/sources.list.d/jenkins.list

Install Jenkins

Install Jenkins package using the apt command.

sudo apt update

sudo apt install -y jenkins

The Jenkins service should now be up and running. You can check the status of the Jenkins service using the below command.

sudo systemctl status jenkins
