Facilitates automated and reproducible experimental research
Every experiment is sacredEvery experiment is greatIf an experiment is wastedGod gets quite irate
Sacred is a tool to help you configure, organize, log and reproduce experiments. It is designed to do all the tedious overhead work that you need to do around your actual experiment in order to:
- keep track of all the parameters of your experiment
- easily run your experiment for different settings
- save configurations for individual runs in a database
- reproduce your results
Sacred achieves this through the following main mechanisms:
- ConfigScopes A very convenient way of the local variables in a function to define the parameters your experiment uses.
- Config Injection: You can access all parameters of your configuration from every function. They are automatically injected by name.
- Command-line interface: You get a powerful command-line interface for each experiment that you can use to change parameters and run different variants.
- Observers: Sacred provides Observers that log all kinds of information about your experiment, its dependencies, the configuration you used, the machine it is run on, and of course the result. These can be saved to a MongoDB, for easy access later.
- Automatic seeding helps controlling the randomness in your experiments, such that the results remain reproducible.

You can directly install it from the Python Package Index with pip:
pip install sacred
Or if you want to do it manually you can checkout the current version from git and install it yourself:
git clone https://github.com/IDSIA/sacred.gitcd sacredpython setup.py install
You might want to also install the numpy and the pymongo packages. They are optional dependencies but they offer some cool features:
pip install numpy, pymongo
The tests for sacred use the py.test package. You can execute them like this:
python setup.py test
There is also a config file for tox so you can automatically run the tests for various python versions like this:
