- Add tito verify command for setup validation and community registration
- Fix broken Dense import in tinytorch/__init__.py (class does not exist)
- Clean up layers.py __all__ to remove non-existent Dense and internal constants
- Add commonly used components to top-level exports:
- AvgPool2d, BatchNorm2d (spatial operations)
- RandomHorizontalFlip, RandomCrop, Compose (data augmentation)
- Total exports now 41 (was 35)
Package exports:
- Fix tinytorch/__init__.py to export all required components for milestones
- Add Dense as alias for Linear for compatibility
- Add loss functions (MSELoss, CrossEntropyLoss, BinaryCrossEntropyLoss)
- Export spatial operations, data loaders, and transformer components
Test infrastructure:
- Create tests/conftest.py to handle path setup
- Create tests/test_utils.py with shared test utilities
- Rename test_progressive_integration.py files to include module number
- Fix syntax errors in test files (spaces in class names)
- Remove stale test file referencing non-existent modules
Documentation:
- Update README.md with correct milestone file names
- Fix milestone requirements to match actual module dependencies
Export system:
- Run tito export --all to regenerate package from source modules
- Ensure all 20 modules are properly exported
- Add quiet=False parameter to enable_autograd()
- Suppress print statements when quiet=True
- Check TINYTORCH_QUIET env var on module import
- Allows CLI tools to import tinytorch silently
- Students still see helpful messages in notebooks
- Updated tinytorch/__init__.py to export all common components at top level
- Changed milestone imports from 'tinytorch.core.*' to 'tinytorch'
- Students now use: from tinytorch import Tensor, Linear, Sigmoid, SGD
- Cleaner API that respects module boundaries
- Added enable_autograd() that enhances operations without modifying source modules
STILL TODO: Fix gradient flow - training not learning yet
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)
Stage 5 of TinyTorch API simplification:
- Created tinytorch.nn package with PyTorch-compatible interface
- Added Module base class in nn.modules for automatic parameter registration
- Added functional module with relu, flatten, max_pool2d operations
- Created tinytorch.optim package exposing Adam and SGD optimizers
- Updated main __init__.py to export nn and optim modules
- Linear and Conv2d now available through clean nn interface
Students can now write PyTorch-like code:
import tinytorch.nn as nn
import tinytorch.nn.functional as F
model = nn.Linear(784, 10)
x = F.relu(model(x))
- Migrated all Python source files to assignments/source/ structure
- Updated nbdev configuration to use assignments/source as nbs_path
- Updated all tito commands (nbgrader, export, test) to use new structure
- Fixed hardcoded paths in Python files and documentation
- Updated config.py to use assignments/source instead of modules
- Fixed test command to use correct file naming (short names vs full module names)
- Regenerated all notebook files with clean metadata
- Verified complete workflow: Python source → NBGrader → nbdev export → testing
All systems now working: NBGrader (14 source assignments, 1 released), nbdev export (7 generated files), and pytest integration.
The modules/ directory has been retired and replaced with standard NBGrader structure.
Sets up the foundational project structure for the TinyTorch ML system, including the CLI entry point, project directories, and setup scripts.
This commit introduces the `tito` CLI for project management, testing, and information display.
It also includes setup scripts to automate environment creation and verification, along with initial documentation.
