Install TensorFlow on Linux

In this tutorial, you'll learn how to install TensorFlow on a Linux PC easily to turn it into a deep learning workstation!

If you want an introduction to deep learning, you can check out my post about installing tensorflow on Windows .

Prerequisites

What you need is:

  • A PC with Ubuntu . I’ve used Ubuntu 16.04 LTS, and maybe it will work with later versions of Ubuntu. However, it’s not going to work with other Linux distributions;
  • An NVidia graphics card in the PC . You can check that your NVidia card is supported here . The tutorial will not work with a graphics card from another brand.

Step 1 : Drivers

Even if you have a nice NVidia graphics card, your PC won’t be able to anything with if can’t talk to it. That’s what drivers are for.

To install TensorFlow, you need NVidia drivers of version 384.X or more recent.

We’re now going to install the latest drivers.
First, let’s add a repository to apt to help us with that:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt upgrade

Then do the following to find out what is the recommended driver:

ubuntu-drivers devices

This gives me:

== /sys/devices/pci0000:16/0000:16:00.0/0000:17:00.0 ==
modalias : pci:v000010DEd00001B06sv00001028sd00003600bc03sc00i00
vendor   : NVIDIA Corporation
driver   : nvidia-396 - third-party free
driver   : nvidia-415 - third-party free recommended
driver   : nvidia-390 - third-party free
driver   : xserver-xorg-video-nouveau - distro free builtin
driver   : nvidia-384 - third-party non-free
driver   : nvidia-410 - third-party non-free

Select the recommended driver and install it:

sudo apt install nvidia-415

Reboot the computer, and check out that everything’s as expected:

nvidia-smi

You should get something like:

+-----------------------------------------------------------------------------+

As you can see, the driver version is correct.

If you want to do further tests and look at nice 3D displays, you could use the phoronix test suite .

Step 2: Deep Learning Software

To do deep learning on your card, you will need the following software (don’t install them, I have an easier solution for you below):

  • CUDA : parallel computing architecture from NVidia. CUDA will make it possible for you to use the many computing cores of your GPU for mathematical calculations.
  • cuDNN : specific library for deep neural networks with CUDA.
  • TensorFlow : Google’s deep learning library
  • Keras : Nice python interface to tensorflow

But installing CUDA and cuDNN manually can be a real pain. Fortunately, we won’t need to do that.

Instead, download anaconda for your system:

  • Choose either the python 2.X or 3.X version
  • make sure to pick the 64-bit installer.

Run the installer.

Install TensorFlow and keras:

conda install tensorflow-gpu keras

In most articles on this blog, we use jupyter and matplotlib to run our code interactively and to display the results. So let's install these packages as well:

conda install jupyter matplotlib

Step 3: Test!

And finally, test it:

python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

I'm getting:
