feat: Change Worker ID

[nastaran78]

Changes in this PR

We introduced two updates related to worker IDs:

Users can now explicitly specify the worker_id in neps.run.

By default, worker IDs follow this format:

worker_i-hostname-pid

where i is a zero-based index.

 
Example: User-specified worker_id
import logging
import numpy as np
import neps

def evaluate_pipeline(float1, float2):
    objective_to_minimize = -float(np.sum([float1, float2]))
    return objective_to_minimize

pipeline_space = dict(
    float1=neps.Float(lower=0, upper=1),
    float2=neps.Float(lower=-10, upper=10),
)

logging.basicConfig(level=logging.INFO)

neps.run(
    evaluate_pipeline=evaluate_pipeline,
    pipeline_space=pipeline_space,
    max_evaluations_total=30,
    worker_id="test_worker",  # user-defined worker_id
)
