Runs zoeken

In deze oefening ga je runs van meerdere Unicorn-experimenten opvragen en alleen die runs teruggeven die aan bepaalde criteria voldoen. Dit is handig tijdens de ML-lifecycle als je run-gegevens moet vergelijken.

Eerst maak je een filterstring om runs te selecteren met een R-squared-metric groter dan .70. Met de functie uit de mlflow-module om runs te doorzoeken sorteer je ze vervolgens in aflopende volgorde en zoek je alleen in de experimenten "Unicorn Sklearn Experiments" en "Unicorn Other Experiments".

De experimenten zijn al in MLflow aangemaakt, inclusief de R-squared-metrics. De MLflow-module wordt geïmporteerd.

In this Chapter, you will be introduced to MLflow and how it aims to assist with some difficulties of the Machine Learning lifecycle. You will be introduced to the four main concepts that make up MLflow with a main focus on MLflow Tracking. You will learn to create experiments and runs as well as how to track metrics, parameters, and artifacts. Finally, you will search MLflow programmatically to find experiment runs that fit certain criteria.

In this Chapter, you will be introduced to MLflow Models. The MLflow Models component of MLflow plays an essential role in the Model Evaluation and Model Engineering steps of the Machine Learning lifecycle. You will learn how MLflow Models standardizes the packaging of ML models as well as how to save, log and load them. You will learn how to create custom MLflow Models to provide more flexibility to your use cases as well as how to evaluate model performance. You will utilize the powerful concept of “Flavors” and finally use the MLflow command line tool for model deployment.

This Chapter introduces the concept of MLflow called the Model Registry. You will be introduced to how the Model Registry is used to manage the lifecycle of ML models. You will learn how to create and search for models in the Model Registry. You then learn how to register models to the Model Registry and learn how to transition models between predefined stages. Finally, you will also learn how to deploy models from the Model Registry.

In this chapter, you'll gain valuable knowledge on how to streamline your data science code for reusability and reproducibility using MLflow Projects. The chapter begins by introducing the concept of MLflow Projects and walking you through creating an MLproject file. From there, you'll learn how to run MLflow Projects through both the command-line and the MLflow Projects module while also discovering the power of using parameters for added flexibility in your code. Finally, you will learn how to manage steps of the machine learning lifecycle by creating a multi-step workflow using MLflow Projects.
