Running a Multi Objective Optimization Directly in Python#

This notebook demonstrates how to:

Write a basic Wrapper in Python and launch a multi objective optimization from Python. If you wanted to launch it from command line, you would do a similar thing of defining the Wrapper, and then put in your configuration file the information about where the wrapper is, and use BOA’s CLI tools. See Running an Experiment from Command Line (Python Wrapper) for more information.

[WARNING 07-13 14:31:07] ax.service.utils.with_db_settings_base: Ax currently requires a sqlalchemy version below 2.0. This will be addressed in a future release. Disabling SQL storage in Ax for now, if you would like to use SQL storage please install Ax with mysql extras via `pip install ax-platform[mysql]`.

Loading the MOO Config File#

Here we can see what the configuration file looks like

The Wrapper#

We define our wrapper in wrapper.py and use a synthetic function that stands in for any black box model call

1Code(Wrapper.path())
from pathlib import Path

import torch

from boa.controller import Controller
from boa.metrics.synthetic_funcs import get_synth_func
from boa.utils import torch_device
from boa.wrappers.base_wrapper import BaseWrapper

tkwargs = {
    "device": torch_device(),
}
Problem = get_synth_func("BraninCurrin")

problem = Problem(negate=True).to(**tkwargs)


class Wrapper(BaseWrapper):
    def run_model(self, trial) -> None:
        pass

    def set_trial_status(self, trial) -> None:
        trial.mark_completed()

    def fetch_trial_data(self, trial, metric_properties, metric_name, *args, **kwargs):
        evaluation = problem(torch.tensor([trial.arm.parameters["x0"], trial.arm.parameters["x1"]]))
        a = float(evaluation[0])
        b = float(evaluation[1])
        return {"branin": a, "currin": b}


def main():
    config_path = Path(__file__).resolve().parent / "moo.yaml"
    wrapper = Wrapper(config_path=config_path)
    controller = Controller(wrapper=wrapper)
    controller.initialize_scheduler()
    return controller.run()


if __name__ == "__main__":
    main()

Start our Experiment#

The Controller will save our scheduler to JSON after it completes the run so we can reload it at a later time for analysis or to resume our experiment
