phitek/keras repository overview

⁠Using Keras via Docker

This directory contains Dockerfile to make it easy to get up and running with Keras via Docker⁠.

⁠Installing Docker

General installation instructions are on the Docker site⁠, but we give some quick links here:

• OSX⁠: docker toolbox⁠
• ubuntu⁠

⁠Running the container

We are using Makefile to simplify docker commands within make commands.

Build the container and start a Jupyter Notebook

$ make notebook

Build the container and start an iPython shell

$ make ipython

Build the container and start a bash

$ make bash

For GPU support install NVIDIA drivers (ideally latest) and nvidia-docker⁠. Run using

$ make notebook GPU=0 # or [ipython, bash]

Switch between Theano and TensorFlow

$ make notebook BACKEND=theano
$ make notebook BACKEND=tensorflow

Mount a volume for external data sets

$ make DATA=~/mydata

Prints all make tasks

$ make help

You can change Theano parameters by editing /docker/theanorc.

Note: If you would have a problem running nvidia-docker you may try the old way we have used. But it is not recommended. If you find a bug in the nvidia-docker report it there please and try using the nvidia-docker as described above.
