Neptune concepts

In Neptune, a run is a unit of an experiment:

run = Run(
    run_id="astute-kittiwake-14",
    experiment_name="seabird-flying-skills",
)

In the model-training code, the run object logs metadata of a current experiment. The metadata can be configs, metrics, and scores.

Inside a run, the logged metadata is organized into namespaces and attributes. Each attribute holds a type of metadata, and attributes can be nested under one or more namespaces (folders).
