This repository serves as the companion code for the O'Reilly book 'Practical MLOps', providing a collection of examples spanning the MLOps lifecycle. It is a hybrid repository with a dominant data research character, containing Jupyter notebooks for exploratory data analysis (e.g., COVID-19 trends, sugar intake correlations), AutoML experiments (Ludwig text classification), and model interoperability scripts (ONNX conversion). It also includes application-like components such as a Flask-based model serving container, CLI tools for CSV linting, and cloud deployment scripts for AWS, Azure, and GCP. The code is organized by book chapters and demonstrates practical MLOps patterns, though many examples are simplified for educational purposes rather than production readiness. The most reusable asset is the modularized CSV linter, which provides a well-structured CLI for data quality checks.
