As a Freelance MLOps Engineer working for Decathlon Digital, I’ve witnessed firsthand the growing need for data scientists to transition into machine learning engineers. The increasing complexity of AI/ML projects demands more than just modeling skills; it requires a deep understanding of software development practices to ensure that models can be deployed, scaled, and maintained effectively in production environments.

This observation sparked the creation of the MLOps Coding Course, an open-source course specifically designed to bridge the gap between data science and software engineering. It’s a comprehensive guide that offers practical knowledge and tools to build, deploy, and manage production-ready AI/ML systems.

MLOps Coding Course:

Why Coding Skills Are Essential for MLOps

The course emphasizes coding best practices because they are fundamental for building robust and maintainable MLOps systems. Strong coding skills enable ML engineers to:

  • Structure code effectively: Organizing code into packages, modules, and functions promotes modularity, reusability, and easier maintenance.
  • Implement robust validation: Applying techniques like typing, linting, and testing ensures code quality, reduces errors, and facilitates collaboration.
  • Automate tasks efficiently: Scripting common tasks with tools like PyInvoke streamlines workflows, saving time and reducing manual effort.
  • Manage dependencies effectively: Utilizing tools like Poetry simplifies the management of dependencies, ensuring consistent environments across development and production.
  • Build reproducible environments: Leveraging containers with Docker ensures consistent deployment environments, mitigating “it works on my machine” issues.

Course Highlights

The MLOps Coding Course aims at establishing a solid foundation. You will learn how to set up your system and installing necessary tools such as Python, pyenv, Poetry, Git, GitHub, and VS Code. The course then dive into prototyping with Jupyter Notebooks, where we cover best practices for managing imports, configurations, datasets, analysis, modeling, and evaluation.

The course then moves on to productionization, guiding you on how to structure code into proper Python packages. You will gain an understanding of modules, programming paradigms like OOP and functional programming, and learn how to set up entry points. We also address externalizing configurations, documenting code effectively, and creating VS Code workspaces to facilitate collaborative development.

A significant portion of the course is dedicated to code validation, a cornerstone of robust MLOps pipelines. You will learn how to implement typing using type hints and tools like Mypy, and learn to lint your code with Ruff for style and quality checks. We also cover testing your code with pytest, including unit testing, fixture usage, and coverage analysis. Further refining your codebase involves exploring logging with Loguru for monitoring and debugging, securing your codebase with tools like Bandit and GitHub Dependabot, and ensuring consistent formatting with Black and Ruff. Lastly, you will gain practical skills in debugging effectively using VS Code’s integrated debugger.

The refining stage of the course goes even further by presenting advanced concepts such as software design patterns like Strategy, Factory, and Adapter, and explores task automation with PyInvoke. You will learn to use pre-commit hooks for early quality checks and set up CI/CD workflows with GitHub Actions. Additionally, we guide you on building and deploying software containers with Docker, tracking and managing ML experiments with MLflow, and utilizing model registries for version control and deployment.

Finally, the course tackles the crucial aspect of sharing your MLOps projects with others. We discuss setting up and managing code repositories, selecting an appropriate software license, writing a comprehensive file, managing project releases, and building code templates with Cookiecutter and cruft. We also cover setting up cloud workstations for collaborative development and strategies for fostering contributions and building a thriving community around your project.

Personalized Support: MLOps Coding Assistant and Mentoring

The course goes beyond static content, offering:

  • MLOps Coding Assistant: A premium AI-powered chatbot specifically trained on the course material to provide tailored responses to your questions and offer code feedback from your inputs.
  • Mentoring Sessions: Personalized guidance and support from experienced MLOps professionals to help you apply the course concepts to your specific challenges.

Companion Repository: MLOps Python Package

To complement the theoretical aspects of the course, we’ve developed the MLOps Python Package, a practical companion repository. This resource serves as a demonstration of the concepts and best practices discussed throughout the course. It offers a flexible, robust, and productive Python package structure that you can use as a foundation for your own MLOps initiatives. By examining the code and structure of the MLOps Python Package, you can gain a deeper understanding of how to apply the course’s teachings to real-world projects, accelerating your journey from theory to practice.

Embracing MLOps for Success
