            hour. The actual metadata.costMilliNodeHours will be equal

            ``cloud``\ (default), the budget must be between 20,000 and
            900,000 milli node hours, inclusive. The default value is
            216,000 which represents one day in wall time, considering 9

            training before the entire training budget has
