Keras

Please note that this application page is referring to the old CentOS software stack which is obsolete and does not work any more with the new Ubuntu setup. You can find an overview on the Ubuntu software stack on this wiki page.

Description

Keras is a high-level neural networks API, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research.

Available versions (Euler, old software stack)

Legacy versions	Supported versions	New versions
		1.1.1, 1.2.0, 1.2.2, 2.0.6, 2.0.8, 2.2.4

Please note that this page refers to installations from the old software stack. There are two software stacks on Euler. Newer versions of software are found in the new software stack.

Interactive session

You can start an interactive Keras session on the login nodes by loading the corresponding modules and starting the Python interpreter.

[leonhard@euler10 ~]$ module load new gcc/4.8.2 python/3.6.0
Autoloading openblas/0.2.13_seq and sqlite/3.15.0
[leonhard@euler10 ~]$ python
Python 3.6.0 (default, Feb 10 2017, 09:00:08) 
[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import keras
Using TensorFlow backend.
>>> keras.__version__
'1.2.2'
>>>

Please note that you should use interactive sessions only for very short test that do not use a lot of CPU capacity. You have to submit all other computations as a batch job.

How to submit a job

Keras is a Python package. Please check Python page for information about how to submit a Python batch job.
