Esecuzione di codice Python in GitHub Actions

In questo esercizio praticherai la scrittura di un workflow di GitHub Actions che esegue uno script Python. Il workflow viene attivato all’apertura di una pull request verso il branch main.

Al termine dell’esercizio, saprai creare workflow di GitHub Actions per script Python. Capirai come attivare i workflow con le pull request, configurare l’ambiente del runner usando le action ed eseguire senza problemi script Python. Queste basi ti permetteranno di automatizzare attività legate a Python all’interno dei workflow di sviluppo software con GitHub Actions.

NOTA: usa python3 invece di python per eseguire gli script Python.

In this chapter, you will explore the essential principles of Continuous Integration/Continuous Delivery (CI/CD) and YAML. You'll grasp the software development life cycle and key terms like build, test, and deploy. Discover the differences between Continuous Integration, Continuous Delivery, and Continuous Deployment. Moreover, you'll investigate the significance of CI/CD in machine learning and experimentation.

Exercise 1: Introduction to Continuous Integration/Continuous Delivery for Machine Learning Exercise 2: Continuous deployment and delivery Exercise 3: Machine learning workflow Exercise 4: Introduction to YAML Exercise 5: YAML syntax Exercise 6: YAML mappings and sequences Exercise 7: Introduction to GitHub Actions Exercise 8: Utility of GitHub Actions Exercise 9: Anatomy of GitHub Actions

Get ready to explore GitHub Actions (GHA), an influential platform for executing CI/CD workflows. Uncover the diverse components of GHA, encompassing events, actions, jobs, steps, runners, and context. Gain insights into crafting workflows that activate upon events like push and pull requests, and tailor runner machines. Dive into hands-on learning as you establish fundamental CI pipelines and grasp the intricacies of the GHA log.

In this chapter, you'll explore the integration of machine learning model training into a GitHub Action pipeline using Continuous Machine Learning GitHub Action. You'll generate a comprehensive markdown report including model metrics and plots. You will also delve into data versioning in Machine Learning by adopting Data Version Control (DVC) to track data changes. The chapter also covers setting DVC remotes and dataset transfers. Finally, you'll explore DVC pipelines, configuring a DVC YAML file to orchestrate reproducible model training.
