class palaestrai.store.database_model.Experiment(**kwargs)

Bases: Base

A whole experiment, including Design of Experiments

Experiments are the master objects of the palaestrAI store. Experiments define a study. This includes variations over parameters as the user wishes. An experiment spawns any number of concrete ::ExperimentRun objects.

class palaestrai.store.database_model.ExperimentRun(**kwargs)

Bases: Base

A concrete experiment run created from an experiment

An experiment run is a concrete instance of an experiment. In it, any parameter variation is replaced by actual parameter settings. An experiment can spawn as many experiment runs as the user wishes. I.e., an experiment run is a concrete configuration.

class palaestrai.store.database_model.ExperimentRunInstance(**kwargs)

Bases: Base

An execution of an experiment run

Each experiment run can be executed as many times as a user wishes. This does not change its outcome, but for reproducibility, such re-runs are sensible. When an experiment run is actually executed - the experiment run being the blue print of an actual execution -, an experiment run instance is created.

palaestrai.store.database_util module

palaestrai.store.database_util.setup_database(uri)

Creates the database from the current model in one go.

Parameters:

uri (str) – The complete database connection URI.

palaestrai.store.database_util.setup_database_v2(store_uri, time_series_uri)

Creates the database from the current model in one go.

Parameters:

• store_uri – The complete database connection URI.

• time_series_uri – The complete database connection URI.

palaestrai.store.database_util.setup_elasticsearch(store_uri)

Creates the database from the current model in one go.

Parameters:

store_uri – The complete database connection URI.

palaestrai.store.database_util.setup_influxdb(time_series_uri)

Creates the database from the current model in one go.

Parameters:

time_series_uri – The complete database connection URI.

palaestrai.store.receiver module

class palaestrai.store.receiver.StoreReceiver(queue, *args, **kwargs)

Bases: Thread

The message receiver of the palaestrAI store.

The store hooks into the global communication, reading every message that is being exchanged between Executor, RunGovernor, AgentConductor, Environment, Brain, and Muscle instances. From these messages, it reads all relevant status information in order to relay them to the store database for later analysis of experiments.

disable()

Disables the store completely.

run()

Run the store.

shutdown()

property uid

write(message)

Main method called to write a message to the buffer.
