- Added typing imports (List, Dict, Tuple, Optional, Set) to export section
- Fixed NameError: name 'List' is not defined
- Fixed milestone copilot references from SimpleTokenizer to CharTokenizer
- Verified transformer learning: 99.1% loss decrease in 500 steps
Training results:
- Initial loss: 3.555
- Final loss: 0.031
- Training time: 52.1s for 500 steps
- Gradient flow: All 21 parameters receiving gradients
- Model: 1-layer GPT with 32d embeddings, 4 heads
Issue: CharTokenizer was failing with NameError: name 'List' is not defined
Root cause: typing imports were not marked with #| export
Fix:
✅ Added #| export directive to import block in tokenization_dev.py
✅ Re-exported module using 'tito export 10_tokenization'
✅ typing.List, Dict, Tuple, Optional, Set now properly exported
Verification:
- CharTokenizer.build_vocab() works ✅
- encode() and decode() work ✅
- Tested on Shakespeare sample text ✅
This fixes the integration with vaswani_shakespeare.py which now properly
uses CharTokenizer from Module 10 instead of manual tokenization.
This commit includes:
- Exported tinytorch package files from nbdev (autograd, losses, optimizers, training, etc.)
- Updated activations.py and layers.py with __call__ methods
- New module exports: attention, spatial, tokenization, transformer, etc.
- Removed old _modidx.py file
- Cleanup of duplicate milestone directories
These are the generated package files that correspond to the source modules
we've been developing. Students will import from these when using TinyTorch.
