Description

Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently.

Available versions (Euler, old software stack)

Legacy versions	Supported versions	New versions
		0.8.2, 0.9.0, 1.0.4

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 Theano session on the login nodes by loading the corresponding modules and starting the Python interpreter.

[sfux@eu-login-09 ~]$ module load new gcc/4.8.2 python/2.7.12
[sfux@eu-login-09 ~]$ python
Python 2.7.12 (default, Nov  2 2016, 13:46:00) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import theano
>>> theano.__version__
'0.8.2'
>>>

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

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