[![Build Status](](
[![PyPI version](](

randopt is a Python package for machine learning experiment management, hyper-parameter optimization, and results visualization. Some of its features include:

* result logging and management,
* human-readable format,
* support for parallelism / distributed / asynchronous experiments,
* command-line and programmatic API,
* shareable, flexible Web visualization,
* automatic hyper-parameter search, and
* pure Python - no dependencies !

# Installation

pip install randopt

# Usage

import randopt as ro

def loss(x):
return x**2

e = ro.Experiment('myexp', {
'alpha': ro.Gaussian(mean=0.0, std=1.0, dtype='float'),

# Sampling parameters
for i in xrange(100):
res = loss(e.alpha)
print('Result: ', res)

# Manually setting parameters
e.alpha = 0.00001
res = loss(e.alpha)

# Search over all experiments results, including ones from previous runs
opt = e.minimum()
print('Best result: ', opt.result, ' with params: ', opt.params)

## Results Visualization

Once you obtained some results, run ` path/to/experiment/folder` to visualize them in your web browser.

For more info on visualization and ``, refer to the [Visualizing Results]() tutorial.

## Hyper-Parameter Optimization

To generate results and search for good hyper-parameters you can either user `` or write your own optimizaiton script using the [Evolutionary]( and [GridSearch]( classes.

For more info on hyper-parameter optimization, refer to the [Optimizing Hyperparams]() tutorial.
