PROBLEM:
- nbdev requires #| export directive on EACH cell to export when using # %% markers
- Cell markers inside class definitions split classes across multiple cells
- Only partial classes were being exported to tinytorch package
- Missing matmul, arithmetic operations, and activation classes in exports
SOLUTION:
1. Removed # %% cell markers INSIDE class definitions (kept classes as single units)
2. Added #| export to imports cell at top of each module
3. Added #| export before each exportable class definition in all 20 modules
4. Added __call__ method to Sigmoid for functional usage
5. Fixed numpy import (moved to module level from __init__)
MODULES FIXED:
- 01_tensor: Tensor class with all operations (matmul, arithmetic, shape ops)
- 02_activations: Sigmoid, ReLU, Tanh, GELU, Softmax classes
- 03_layers: Linear, Dropout classes
- 04_losses: MSELoss, CrossEntropyLoss, BinaryCrossEntropyLoss classes
- 05_autograd: Function, AddBackward, MulBackward, MatmulBackward, SumBackward
- 06_optimizers: Optimizer, SGD, Adam, AdamW classes
- 07_training: CosineSchedule, Trainer classes
- 08_dataloader: Dataset, TensorDataset, DataLoader classes
- 09_spatial: Conv2d, MaxPool2d, AvgPool2d, SimpleCNN classes
- 10-20: All exportable classes in remaining modules
TESTING:
- Test functions use 'if __name__ == "__main__"' guards
- Tests run in notebooks but NOT on import
- Rosenblatt Perceptron milestone working perfectly
RESULT:
✅ All 20 modules export correctly
✅ Perceptron (1957) milestone functional
✅ Clean separation: development (modules/source) vs package (tinytorch)
- Change from checking only first line to first 5 lines for AUTOGENERATED marker
- Fixes issue where nbdev exports put AUTOGENERATED on line 3, not line 1
- Now properly removes all 26 exported module files during reset
- Verified clean reset: tinytorch/core/ only contains __init__.py after reset
- Move export functionality from 'tito package export' to 'tito module export'
- Require --all flag for exporting all modules (consistent with test command)
- Remove export from package command group to eliminate duplication
- Update help text and examples across all commands
- Fix tensor module arithmetic operators for complete functionality
- Clean up duplicate _quarto.yml and sidebar.yml files in modules/
This creates a consistent CLI pattern:
- tito module export --all (export all modules)
- tito module export --module <name> (export specific module)
- tito module test --all (test all modules)
- tito module test --module <name> (test specific module)
- Rename SyncCommand to ExportCommand and sync.py to export.py
- Update all CLI references from 'tito package sync' to 'tito package export'
- Update help text and internal messages to use 'Export' terminology
- Update imports across all command files
- Update help text in main CLI, reset, clean, info, and notebooks commands
- Command now clearly communicates that it exports notebook code to Python package
- Maintains same functionality but with clearer naming for user experience
- Ported all commands from bin/tito.py to new tito/ CLI architecture
- Added InfoCommand with system info and module status
- Added TestCommand with pytest integration
- Added DoctorCommand with environment diagnosis
- Added SyncCommand for nbdev export functionality
- Added ResetCommand for package cleanup
- Added JupyterCommand for notebook server
- Added NbdevCommand for nbdev development tools
- Added SubmitCommand and StatusCommand (placeholders)
- Fixed missing imports in tinytorch/core/tensor.py
- All commands now work with 'tito' command in shell
- Maintains professional architecture while restoring full functionality
Commands restored:
✅ info - System information and module status
✅ test - Run module tests with pytest
✅ doctor - Environment diagnosis
✅ sync - Export notebooks to package
✅ reset - Clean tinytorch package
✅ nbdev - nbdev development commands
✅ jupyter - Start Jupyter server
✅ submit - Module submission
✅ status - Module status
✅ notebooks - Build notebooks from Python files
The CLI now has both the professional architecture and all original functionality.
