How to setup TensorFlow on Ubuntu

How to setup TensorFlow on Ubuntu - This tutorial will help you set up TensorFlow 1.12 on Ubuntu 16.04 with a GPU using Docker and nvidia-docker.

TensorFlow is one of the most popular deep-learning libraries. It was created by Google and was released as an open-source project in 2015. TensorFlow is used for both research and production environments. Installing TensorFlow can be cumbersome. The difficulty varies based on your environment constraints, and more when you’re a data scientist that just wants to build your neural networks.

When using TensorFlow on GPU — setting up requires a few steps. In the following tutorial, we will go over the process required to set up TensorFlow.

Requirements:

Step 1 — Prepare your environment with Docker and Nvidia-Docker

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. What exactly is a container? Containers allow data scientists and developers to wrap up an environment with all of the parts it needs — such as libraries and other dependencies — and ship it all out in one package.

To use docker with GPUs and to be able to use TensorFlow in your application, you’ll need to install Docker with Nvidia-Docker. If you already have those installed, move to the next step. Otherwise, you can follow our previous guide to installing nvidia docker.

Prerequisites:

Step 2 — Dockerfile

Docker can build images (environments) automatically by reading the instructions from a Dockerfile. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

In our case, those commands will describe the installation of Python 3.6, CUDA 9 and CUDNN 7.2.1 — and of course the installation of TensorFlow 1.12 from source.

For this environment, we will use the following Dockerfile

FROM nvidia/cuda:9.0-base-ubuntu16.04

Step 3 — Running Dockerfile

To build the image from the Dockerfile, simply run the docker build command. Keep in mind that this build process might take a few hours to complete. We recommend using nohup utility so that if your terminal hangs — it will still run.

$ docker build -t deeplearning -f Dockerfile

This should output the setup process and should end with something similar to:

>> Successfully built deeplearning (= the image ID)

Your image is ready to use. To start the environment, simply type in the below command. But, don’t forget to replace your image id:

$ docker run --runtime=nvidia -it deeplearning /bin/bashStep 4 — Validating TensorFlow & start building!

Validate that TensorFlow is indeed running in your Dockerfile

sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

Congrats! Your new TensorFlow environment is set up and ready to start training, testing and deploying your deep learning models!

Conclusion

Tensorflow has truly disrupted the machine learning world by offering a solution to build production-ready models at scale. But Tensorflow is not always the most user-friendly. It can be difficult to smoothly incorporate into your machine learning pipeline. cnvrg.io data science platform leverages Tensorflow and other open-source tools so that data scientists can focus on the magic — the algorithms. You can find more tutorials on how to easily leverage open-source tools like TensorflowHow to set up Kubernetes for your machine learning workflows, and How to run Spark on Kubernetes. Finding simple ways to integrate these useful tools will get your models closer to production.

Learn how to install and use Docker Community Edition (CE) on Ubuntu 18.04. Learn how to install Docker, worked with images and containers, and pushed a modified image to Docker Hub. Docker is an application that simplifies the process of managing application processes in containers. Containers let you run your applications in resource-isolated processes. They’re similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.
