Deep Learning in Spark, with Python

This project is no longer maintained since June 2017. Sorry for the inconvenience.

Learninspy is a framework for building deep neural networks using Spark features on Python API (PySpark). The project was started in April 2015 by Leandro Ferrado, and it aims to exploit distributed computing capabilities provided by Spark to build and train neural networks with Deep Learning in a simple and flexible way. So, the key features pursued here are:

• Simple and easy-to-follow: That's why Python was chosen as the basis for developing on Spark, so this project must be easy to reuse in any application of deep learning.
• Extensible: It has many degrees of freedom on its feature definitions (e.g. activation functions, optimization algorithms and stop criterions, hyper-parameters setup, etc) and of course in a simple way!.
• Distributed flavor: Taking advantage of Spark, the main power of learninspy lies in the distribution of both data pre-processing and optimization of neural networks.

• Python 2.7.x
• Spark[>=1.3.x, 2.0.x]
• NumPy
• Matplotlib

NOTE: it is needed to have defined an environment variable called SPARK_HOME pointing to the Spark's root directory (e.g. /usr/local/spark/). You can follow the installation guide detailed on install_spark.md file. In addition, if you want to connect Learninspy with a Spark's standalone cluster, you need to define the following environment variables: SPARK_MASTER_IP to specify the master's IP address, and SPARK_MASTER_PORT for its application port.

Run nosetests test/ from the download directory.

On the folder examples/ you can find some "demos" (Python files & Notebooks) in order to know how can be used Learninspy on datasets.
