Membuat Kelas Python kustom

MLflow menyediakan cara untuk membuat model kustom agar dapat mendukung beragam kasus penggunaan. Untuk membuat model kustom, MLflow memungkinkan pengguna membuat sebuah Kelas Python yang mewarisi Kelas mlflow.pyfunc.PythonModel. Kelas PythonModel menyediakan kustomisasi dengan menyediakan metode untuk logika inferensi kustom dan dependensi artefak.

Pada latihan ini, Anda akan membuat Kelas Python baru untuk model kustom yang memuat model tertentu dan kemudian mendekode label setelah inferensi. Modul mlflow akan diimpor.

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

# Create Python Class
class ____(mlflow.pyfunc.PythonModel):
    # Set method for loading model
    def ____(self, context):
        self.model = mlflow.sklearn.load_model("./lr_model/")
    # Set method for custom inference     
    def ____(self, context, model_input):
        predictions = self.model.predict(model_input)
        decoded_predictions = []  
        for prediction in predictions:
            if prediction == 0:
                decoded_predictions.append("female")
            else:
                decoded_predictions.append("male")
        return decoded_predictions

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.

Exercise 1: What is MLflow?Exercise 2: Components of MLflow Exercise 3: MLflow experiments Exercise 4: MLflow Tracking Exercise 5: Starting a run Exercise 6: Logging a run Exercise 7: How to retrieve active run data?Exercise 8: Querying runs Exercise 9: Search runs query options Exercise 10: Searching runs

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.
