Assigning a Bayesian sampling algorithm for a SweepJob

from azure.ai.ml.sweep import BayesianSamplingAlgorithm, Objective, SweepJob, SweepJobLimits
command_job = CommandJob(
inputs=dict(kernel="linear", penalty=1.0),
compute=cpu_cluster,
environment=f"{job_env.name}:{job_env.version}",
code="./scripts",
command="python scripts/train.py --kernel $kernel --penalty $penalty",
experiment_name="sklearn-iris-flowers",
)
sweep = SweepJob(
sampling_algorithm=BayesianSamplingAlgorithm(),
trial=command_job,
search_space={"ss": Choice(type="choice", values=[{"space1": True}, {"space2": True}])},
inputs={"input1": {"file": "top_level.csv", "mode": "ro_mount"}},
compute="top_level",
limits=SweepJobLimits(trial_timeout=600),
objective=Objective(goal="maximize", primary_metric="accuracy"),
