Editing Tutorials:container which trains MNIST using Tensorflow (section)

== Pre-requisites ==

You have prepared your system according to the previous tutorials, in particular,
# you have a working version of nvidia-docker installed on your system.
# you are logged into the nVidia GPU cloud docker registry.
# if you want to run the examples directly on your own system, without using a container, you also have to install Tensorflow for Python and a number of recommended packages. On Ubuntu:

<syntaxhighlight lang="bash">
# make sure you do this only if you have not installed
# tensorflow already from another source (i.e. self-compiled).
sudo apt install python-pip python-setuptools
sudo -H pip install scipy numpy tensorflow-gpu
</syntaxhighlight>
