Introduction

These tutorials are intended for beginners in Deep Learning and TensorFlow.
Each tutorial covers a single topic.
The source-code is well-documented.
There is a YouTube video for each tutorial.

Tutorials

Videos

These tutorials are also available as YouTube videos.

Older Versions

Sometimes the source-code has changed from that shown in the YouTube videos. This may be due to bug-fixes, improvements, or because code-sections are moved to separate files for easy re-use.

If you want to see the exact versions of the source-code that were used in the YouTube videos, then you can browse the history of commits to the GitHub repository.

Downloading

Some of the Python Notebooks use source-code located in different files to allow for easy re-use across multiple tutorials. It is therefore recommended that you download the whole repository from GitHub, instead of just downloading the individual Python Notebooks.

Git

The easiest way to download and install these tutorials is by using git from the command-line:

git clone https://github.com/Hvass-Labs/TensorFlow-Tutorials.git

This will create the directory TensorFlow-Tutorials and download all the files to it.

This also makes it easy to update the tutorials, simply by executing this command inside that directory:

git pull

Zip-File

You can also download the contents of the GitHub repository as a Zip-file and extract it manually.

Installation

There are different ways of installing and running TensorFlow. This section describes how I did it for these tutorials. You may want to do it differently and you can search the internet for instructions.

If you are new to using Python and Linux, etc. then this may be challenging to get working and you may need to do internet searches for error-messages, etc. It will get easier with practice.

Python Version 3.5 or Later

These tutorials were developed on Linux using Python 3.5 / 3.6 (the Anaconda distribution) and PyCharm.

There are reports that Python 2.7 gives error messages with these tutorials. Please make sure you are using Python 3.5 or later!

Environment

After installing Anaconda, you should create a conda environment so you do not destroy your main installation in case you make a mistake somewhere:

conda create --name tf python=3

Now you can switch to the new environment by running the following (on Linux):

source activate tf

Required Packages

The tutorials require several Python packages to be installed. The packages are listed in requirements.txt First you need to edit this file and select whether you want to install the CPU or GPU version of TensorFlow.

To install the required Python packages and dependencies you first have to activate the conda-environment as described above, and then you run the following command in a terminal:

pip install -r requirements.txt

Note that the GPU-version of TensorFlow also requires the installation of various NVIDIA drivers, which is not described here.

Testing

You should now be able to run the tutorials in the Python Notebooks:

cd ~/development/TensorFlow-Tutorials/  # Your installation directory.
jupyter notebook

This should start a web-browser that shows the list of tutorials. Click on a tutorial to load it.
