Tensorflow is an open source, deep learning software library for numerical computation using data flow graphs. Detailed information about the software is available on the project website:

The library is available as a python package. It is installed for python/2.7.5 and requires 3 additional dependencies gcc/4.9.1 mkl/16.0.1 java/sunjdk_1.8.0

tres0118:pwolinsk:$ module load gcc/4.9.1 python/2.7.5 mkl/16.0.1 java/sunjdk_1.8.0
tres0118:pwolinsk:$ python
Python 2.7.5 (default, Jul 10 2014, 16:10:08) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow

The tensorflow package is installed on Razor in /share/apps/opt/rh/python27/root/usr/lib/python2.7/site-packages/tensorflow. The installation contains a few example models: image/alexnet image/cifar10 image/imagenet image/mnist embedding.

We will use the image/mnist training model to run a training session.

The -m option instructs python to search the PYTHON path for a specified program name. You could also specify the full path to the script.
