Mencatat dan memuat model

Model API menyediakan cara untuk berinteraksi dengan model dengan mencatat (logging) dan memuatnya langsung dari MLflow Tracking secara terstandar. Kemampuan berinteraksi dengan model sangat penting selama siklus ML pada langkah Model Engineering dan Model Evaluation.

Pada latihan ini Anda akan membuat model Linear Regression dari scikit-learn menggunakan himpunan data Unicorn. Model ini akan dicatat ke MLflow Tracking dan kemudian dimuat menggunakan run_id yang digunakan untuk mencatat artefak.

Pertama, Anda akan mencatat model menggunakan pustaka scikit-learn dari modul MLflow. Lalu Anda akan memuat model dari MLflow Tracking menggunakan run_id.

Model akan dilatih dan diberi nama lr_model.

lr_model = LinearRegression()
lr_model.fit(X_train, y_train)

Modul mlflow akan diimpor.

Petunjuk latihan

Catat model ke MLflow Tracking di bawah jalur artefak "lr_tracking".
Buat variabel bernama run yang diatur ke run terakhir.
Buat variabel lain bernama run_id yang diatur ke run_id dari variabel run.
Muat model menggunakan run_id dan jalur artefak yang digunakan untuk mencatat model.

Latihan interaktif praktis

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.
