S1L1 -Python Memory Model & Object References | Silent ML Bugs Start Here | Python as Runtime System

Описание: Python Memory Model & Object References | Silent ML Bugs Start Here | S1 L1

Why does model accuracy suddenly change when you didn’t touch the architecture?
Why do hyperparameters leak across experiments?
Why does your ML pipeline behave differently on the second run?

The answer often lies in something most engineers underestimate — Python’s memory model.

In this foundational lecture of AI Engineering Foundations – Season 1, we go deep into:

Variables as references (not containers)
Stack vs Heap memory visualization
CPython reference counting
Mutable vs Immutable objects
Shallow vs Deep copy (nested configuration traps)
Identity (is) vs Equality (==)
Default mutable argument pitfalls
Real ML pipeline mutation bugs
How silent data corruption happens in production

We don’t just explain theory — we apply everything inside our evolving project:
Mini Project 1 – OS-Automator, where we start building a professional, structured ML-ready Python repository.

This lecture sets the foundation for reliable ML engineering.
If you don’t understand memory discipline, you cannot build reproducible AI systems.

By the end of this session, you will:

✔ Understand how Python actually handles objects
✔ Avoid silent data corruption in ML pipelines
✔ Write mutation-safe functions
✔ Structure code like an engineer, not a script writer

This is not beginner Python.
This is Python for AI/ML Engineers.
