How to Install TensorFlow on Ubuntu 20.04

Tensorflow is a free and end-to-end open-source machine learning platform created by the Google Brain team. It is a library used for numerical computation and large-scale machine learning. You can install it in a Python virtual environment or using Anaconda, as a docker container. It comes with a set of libraries and community resources that helps you to develop machine learning programs and applications.

In this tutorial, we will show you how to install Tensorflow with Docker on Ubuntu 20.04.

Step 1 – Install Docker CE

First, install all required dependencies with the following command:

apt-get install git apt-transport-https ca-certificates curl software-properties-common -y

Next, add the Docker GPG key and repository with the following command:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Once the repository has been added, install the Docker and Docker compose with the following command:

apt-get install docker-ce -y

Once the installation is completed, verify the Docker version with the following command:

docker --version

You should see the following output:

Docker version 20.10.5, build 55c4c88

Step 2 – Launch Tensorflow Container

Docker provides a Tensorflow container for building machine learning applications.

First, download the Tensorflow container using the following command:

docker pull tensorflow/tensorflow:latest

You should get the following output:

latest: Pulling from tensorflow/tensorflow
d519e2592276: Pull complete 
d22d2dfcfa9c: Pull complete

Digest: sha256:0118f3db64ddadf5d16f4b8d85ffb14228e194c0211c690562fb5dfd16fc86c0
Status: Downloaded newer image for tensorflow/tensorflow:latest
docker.io/tensorflow/tensorflow:latest

Next, create a Tensorflow container from the downloaded image with the following command:

docker run -it -p 8888:8888 tensorflow/tensorflow:latest

You will be redirected inside the Tensorflow container:

________                               _______________                
___  __/__________________________________  ____/__  /________      __
__  /  _  _ \_  __ \_  ___/  __ \_  ___/_  /_   __  /_  __ \_ | /| / /
_  /   /  __/  / / /(__  )/ /_/ /  /   _  __/   _  / / /_/ /_ |/ |/ / 
/_/    \___//_/ /_//____/ \____//_/    /_/      /_/  \____/____/|__/


WARNING: You are running this container as root, which can cause new files in
mounted volumes to be created as the root user on your host machine.

To avoid this, run the container by specifying your user's userid:

$ docker run -u $(id -u):$(id -g) args...

root@f8968eb6e582:/#

You can now write and run any application inside the container. You can exit from the container anytime using the following command:

exit

Step 3 – Launch Tensorflow Jupyter Container

Docker also provides a Tensorflow container with Jupyter notebook that allows you to write and run code through the Jupyter notebook dashboard.

You can download and launch the Tensorflow Jupyter container with the following command:

docker run -it -p 8088:8088 tensorflow/tensorflow:latest-jupyter

You should get the following output:
