IMPORT PATH FIXES: All modules now reference correct directories
Fixed Paths:
✅ 02_tensor → 01_tensor (in all modules)
✅ 03_activations → 02_activations (in all modules)
✅ 04_layers → 03_layers (in all modules)
✅ 05_losses → 04_losses (in all modules)
✅ Added comprehensive fallback imports for 07_training
Module Test Status:
✅ 01_tensor, 02_activations, 03_layers: All tests pass
✅ 06_optimizers, 08_spatial: All tests pass
🔧 04_losses: Syntax error (markdown in Python)
🔧 05_autograd: Test assertion failure
🔧 07_training: Import paths fixed, ready for retest
All import dependencies now correctly reference reorganized module structure.
CLEANUP: Removed duplicate/obsolete configuration files
Removed Files:
- All old numbered .yml files (02_tensor.yml, 03_activations.yml, etc.)
- These were leftover from the module reorganization
- Had incorrect dependencies (still referenced 'setup')
Current State:
✅ CLI correctly uses module.yaml files (19 modules)
✅ All module.yaml files have correct dependencies
✅ No more duplicate/conflicting configuration files
✅ Clean module structure with single source of truth
The CLI was already using module.yaml correctly, so this cleanup removes
the confusing duplicate files without affecting functionality.
PERFECT WORKFLOW: Clean lifecycle commands with distinct purposes
New Commands (No Overlaps):
✅ tito module start 01 → Start working on module (first time only)
✅ tito module resume 01 → Resume working on module (continue work)
✅ tito module complete 01 → Complete module (test + export)
✅ tito module status → Show progress with 3 states
Smart Features:
✅ State tracking: ⏳ not started → 🚀 in progress → ✅ completed
✅ Smart validation: start checks if already started, suggests resume
✅ Smart defaults: resume/complete work without module number
✅ Progress persistence: JSON file tracks started/completed modules
✅ Clear guidance: Always shows next logical step
User Journey:
1. tito setup → Environment setup
2. tito module start 01 → Begin tensors (marks as started)
3. Work in Jupyter, save → Natural development
4. tito module complete 01 → Test, export, mark completed
5. tito module start 02 → Begin activations
6. tito module resume 02 → Continue activations later
No command overlaps - each has distinct purpose and clear mental model!

Added comprehensive ASCII diagrams to Perceptron example:
- Visualization of how decision boundary learns over epochs
- Mathematical explanation of gradient descent
- Clear before/during/after training states
Cleaned up unnecessary files:
- Removed optimization_pipeline_complete.py
- Removed profile_and_optimize_demo.py
- Removed quantize_and_compress_demo.py
- Removed pretrained/ directory with weights
- Removed duplicate data/ directory from CIFAR example
The examples directory is now cleaner and focused on the 5 milestone examples.
Each example now has its own README explaining:
- Prerequisites and module dependencies
- How to run the example
- Dataset details (size, source, caching)
- Expected results and training times
- Architecture diagrams
- Historical significance
- Troubleshooting tips
Dataset improvements:
- Better progress bar with MB downloaded/total
- Visual progress indicator [████░░░░] style
- Clear feedback about download status
This addresses the confusion about how datasets work:
- DataLoader (Module 10) doesn't download data, just batches it
- DataManager handles downloads and caching
- Each example explains its data requirements clearly
- Self-contained folders with everything needed
- CIFAR CNN now uses YOUR DataLoader from Module 10 for batching and shuffling
- Created CIFARDataset class that implements YOUR Dataset interface
- Training and testing both use DataLoader for efficient batch iteration
- Fixed Conv2D → Conv2d import (multi-channel version with proper API)
- Updated module dependencies and documentation
Note: MNIST MLP doesn't use DataLoader (runs after Module 8, before Module 10)
Note: GPT example uses hardcoded demo tokens, doesn't need DataLoader
