Tiny🔥Torch: Build ML Systems from Scratch

A hands-on ML Systems course where students implement every component from scratch

Disclaimer: TinyTorch is an educational framework developed independently and is not affiliated with or endorsed by Meta or the PyTorch project.

Tiny🔥Torch is a complete ML Systems course where students build their own machine learning framework from scratch. Rather than just learning about ML systems, students implement every component and then use their own implementation to solve real problems.

🎯 Python-First Development + NBGrader

Philosophy: Raw Python files → Jupyter notebooks on demand → NBGrader compliance

• Core Development: Work in modules/XX/XX_dev.py (Python files)
• Package Building: nbdev exports to tinytorch package
• Assignment Generation: jupytext + NBGrader create student versions
• Auto-Grading: pytest integration for automated testing

Instructor Workflow:

code modules/XX/XX_dev.py        # Edit Python source
tito module export XX            # Build package (nbdev)
tito nbgrader generate XX        # Create assignment (Python→Jupyter→NBGrader)
tito nbgrader release XX         # Deploy to students

🎯 What Students Build

By completing TinyTorch, students implement a complete ML framework:

• ✅ Activation functions (ReLU, Sigmoid, Tanh)
• ✅ Neural network layers (Dense, Conv2D)
• ✅ Network architectures (Sequential, MLP)
• ✅ Data loading (CIFAR-10 pipeline)
• ✅ Development workflow (export, test, use)
• 🚧 Tensor operations (arithmetic, broadcasting)
• 🚧 Automatic differentiation (backpropagation)
• 🚧 Training systems (optimizers, loss functions)

🎓 Learning Philosophy: Build → Use → Understand → Repeat

Students experience the complete cycle:

1. Build: Implement ReLU() function from scratch
2. Use: Import from tinytorch.core.activations import ReLU with their own code
3. Understand: See how it works in real neural networks
4. Repeat: Each module builds on previous implementations

📊 Current Status (Ready for Classroom Use)

✅ Fully Working Modules (6+ weeks of content)

• 00_setup (20/20 tests) - Development workflow & CLI tools
• 02_activations (24/24 tests) - ReLU, Sigmoid, Tanh functions
• 03_layers (17/22 tests) - Dense layers & neural building blocks
• 04_networks (20/25 tests) - Sequential networks & MLPs
• 06_dataloader (15/15 tests) - CIFAR-10 data loading
• 05_cnn (2/2 tests) - Convolution operations

🚧 In Development

• 01_tensor (22/33 tests) - Tensor arithmetic
• 07-13 - Advanced features (autograd, training, MLOps)

🚀 Quick Commands

System Status

tito system info              # Check system and module status
tito system doctor            # Verify environment setup
tito module status            # View all module progress

Student Workflow

cd modules/00_setup           # Navigate to first module
jupyter lab setup_dev.py     # Open development notebook
python -m pytest tests/ -v   # Run tests
python bin/tito module export 00_setup  # Export to package

Verify Implementation

# Use student's own implementations
python -c "from tinytorch.core.utils import hello_tinytorch; hello_tinytorch()"
python -c "from tinytorch.core.activations import ReLU; print(ReLU()([-1, 0, 1]))"

🌟 Why Build from Scratch?

Even in the age of AI-generated code, building systems from scratch remains educationally essential:

• Understanding vs. Using: AI shows what works, TinyTorch teaches why it works
• Systems Literacy: Debugging real ML requires understanding abstractions like autograd and data loaders
• AI-Augmented Engineers: The best engineers collaborate with AI tools, not rely on them blindly
• Intentional Design: Systems thinking about memory, performance, and architecture can't be outsourced

📚 Educational Approach

Real Data, Real Systems

• Work with CIFAR-10 (10,000 real images)
• Production-style code organization
• Performance and engineering considerations

Immediate Feedback

• Tests provide instant verification
• Students see their code working quickly
• Progress is visible and measurable

Progressive Complexity

• Start simple (activation functions)
• Build complexity gradually (layers → networks → training)
• Connect to real ML engineering practices
