Decorate a Function with once

Zero configuration

Apply @stet.once with no arguments to use all defaults: all parameters as the key, store in _stet_store.csv:

import stet

@stet.once
def run_experiment(alpha, seed):
    ...

Specify a store

Pass store= to control where runs are recorded:

@stet.once(store='markov_runs.csv')
def run_experiment(alpha, seed):
    ...

The backend is selected from the file extension. See Choose a Backend.

Specify key parameters

Pass key= to declare which parameters define experiment identity. Parameters not in key are ignored for the purpose of deciding whether a run is skipped:

@stet.once(store='markov_runs.csv', key=['alpha', 'seed'])
def run_experiment(alpha, seed, n_iter=1000):
    ...

See Choose Key Parameters for guidance on what to include.
