# Serious Development Path

Perfect for: “I want to build this myself” • “This is my class assignment” • “I want to understand ML frameworks deeply”

## What You’ll Build

A complete ML framework from scratch, including:

- Your own tensor library with operations and autograd

- Neural network components (layers, activations, optimizers)

- Training systems that work on real datasets (CIFAR-10)

- Production features (compression, monitoring, benchmarking)

- Language models that extend your vision framework to TinyGPT

End result: A working ML framework that powers both computer vision AND language models.

## Quick Start (5 minutes)

### Step 1: Get the Code

    git clone https://github.com/your-org/tinytorch.git
    cd TinyTorch

### Step 2: Setup Environment

    # Activate virtual environment
    source bin/activate-tinytorch.sh

    # Install dependencies
    make install

    # Verify everything works
    tito system doctor

### Step 3: Start Building

    # Open first assignment
    cd modules/source/01_setup
    jupyter lab setup_dev.py

### Step 4: Build → Test → Export → Use

    # After implementing code in the notebook:
    tito export               # Export your code to tinytorch package
    tito test setup          # Test your implementation

    # Now use YOUR own code:
    python -c "from tinytorch.core.setup import hello_tinytorch; hello_tinytorch()"
    # 🔥 TinyTorch! Built by: [Your Name]

## Development Workflow

### The `tito` CLI System

TinyTorch includes a complete CLI for professional development:

    # System management
    tito system doctor          # Check environment health
    tito system info           # Show module status

    # Module development
    tito export                # Export dev code to package
    tito test setup            # Test specific module
    tito test --all            # Test everything

    # NBGrader integration
    tito nbgrader generate setup    # Create assignments
    tito nbgrader release setup     # Release to students
    tito nbgrader autograde setup   # Auto-grade submissions

### Quality Assurance

Every module includes comprehensive testing:

- 100+ automated tests ensure correctness

- Inline tests provide immediate feedback

- Integration tests verify cross-module functionality

- Performance benchmarks track optimization

## Proven Student Outcomes

Real Results

After 6-8 weeks, students consistently:

✅ Build multi-layer perceptrons that classify CIFAR-10 images
✅ Implement automatic differentiation from scratch
✅ Create custom optimizers (SGD, Adam) that converge reliably
✅ Optimize models with pruning and quantization
✅ Deploy production ML systems with monitoring
✅ Understand framework internals better than most ML engineers
🔥 Extend their vision framework to language models with 95% reuse

Test Coverage: 200+ tests across all modules ensure student implementations work

## Why This Approach Works

### Build → Use → Understand

Every component follows this pattern:

1. 🔧 Build: Implement `ReLU()` from scratch

2. 🚀 Use: `from tinytorch.core.activations import ReLU` - your code!

3. 💡 Understand: See how it enables complex pattern learning

### Real Data, Real Systems

- Work with CIFAR-10 (not toy datasets)

- Production-style code organization

- Performance and engineering considerations

- Professional development practices

### Immediate Feedback

- Code works immediately after implementation

- Visual progress indicators and success messages

- Comprehensive error handling and guidance

- Professional-quality development experience
