Python, library, machine learning


TensorFlow is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.

Interactive session

You can start an interactive TensorFlow session on the login nodes by loading the corresponding modules and starting the Python interpreter.
[leonhard@euler01 ~]$ module load new gcc/4.8.2 python/3.6.0
Autoloading openblas/0.2.13_seq and sqlite/3.15.0
[leonhard@euler01 ~]$ 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 tensorflow as tf
>>> tf.__version__
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
b'Hello, TensorFlow!'
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

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