icflow 0.2.0

A collection of simple utilities for machine learning workflows.

icflow is a Python package with some prototype workflow tools for use at the Irish Centre for High End Computing (ICHEC).

It is intended to help standardize some of our workflows in areas like Machine Learning by using common utilities, data-formats and data-structures.

See the project documentation on ReadTheDocs.

Features

Parameter Sweep

You can define a parameter sweep in a yaml file as follows:

title: "my_parameter_sweep"
program: "launch_program"  

parameters:
    param_0 : 1
    param_1 : "my_value"
    param_2 : [1, 2]
    param_3 : ["a", "b"]

Running:

icflow sweep --config my_config.yaml

with this fill will launch the program or script defined by program, which should be in the system PATH.

The listed parameters are passed as command line arguments to the program in the form --key value. Parameter value lists are expanded such that there is a program launch for each combination of values in the list. In the above example this will result in the following program launches:

launch_program --param_0 1 --param_1 my_value --param_2 1 --param_3 a
launch_program --param_0 1 --param_1 my_value --param_2 2 --param_3 a
launch_program --param_0 1 --param_1 my_value --param_2 1 --param_3 b
launch_program --param_0 1 --param_1 my_value --param_2 2 --param_3 b

Program launching is handled internally by ICHEC's ictasks library, with each of these program launches handled as a 'task'.
