The itemize environment parameters [leftmargin=*, itemsep=1pt, parsep=0pt]
were appearing as visible text in the PDF because the enumitem package
wasn't loaded. This fix adds \usepackage{enumitem} to the preamble.
All itemized lists now format correctly with proper spacing and margins.

Added all module development files to modules/XX_name/ directories:
Module notebooks and scripts:
- 18 modules with .ipynb and .py files (01-20, excluding some gaps)
- Moved from modules/source/ to direct module directories
- Includes tensor, autograd, layers, transformers, optimization modules
Module README files:
- Added README.md for modules with additional documentation
- Complements ABOUT.md files added earlier
This completes the module restructuring:
- Before: modules/source/XX_name/*_dev.{py,ipynb}
- After: modules/XX_name/*_dev.{py,ipynb}
All development happens directly in numbered module directories now.
- Remove circular imports where modules imported from themselves
- Convert tinytorch.core imports to sys.path relative imports
- Only import dependencies that are actually used in each module
- Preserve documentation imports in markdown cells
- Use consistent relative path pattern across all modules
- Remove hardcoded absolute paths in favor of relative imports
Affected modules: 02_activations, 03_layers, 04_losses, 06_optimizers,
07_training, 09_spatial, 12_attention, 17_quantization
- Remove demonstrate_complex_computation_graph() function from Module 05 (autograd)
- Remove demonstrate_optimizer_integration() function from Module 06 (optimizers)
- Module 04 (losses) had no demonstration functions to remove
- Keep all core implementations and unit test functions intact
- Keep final test_module() function for integration testing
- All module tests continue to pass after cleanup(https://claude.ai/code)
This change ensures tests run immediately when developing modules but don't execute when modules are imported by other modules.
Changes:
- Protected all test executions with if __name__ == "__main__" blocks
- Unit tests run immediately after function definitions during development
- Module integration test (test_module()) runs at end when executed directly
- Updated module-developer.md with new testing patterns and examples
Benefits:
- Students see immediate feedback when developing (python module_dev.py runs all tests)
- Clean imports: later modules can import earlier ones without triggering tests
- Maintains educational flow: tests visible right after implementations
- Compatible with nbgrader and notebook environments
Tested:
- Module 01 runs all tests when executed directly ✓
- Importing Tensor from tensor_dev doesn't run tests ✓
- Cross-module imports work without test interference ✓
Major changes to module structure:
1. Updated module-developer.md with clear components-only rule
2. Removed Sequential container from Module 03 (layers)
3. Converted to manual layer composition for transparency
Philosophy:
- Modules build ATOMIC COMPONENTS (Tensor, Linear, ReLU, etc.)
- Milestones/Examples show EXPLICIT COMPOSITION
- Students SEE how their components connect
- No hidden abstractions or black boxes
Module 03 changes:
- REMOVED: Sequential class and tests (~200 lines)
- KEPT: Linear and Dropout as individual components
- UPDATED: Integration demos use manual composition
- Result: Students see explicit layer1.forward(x) calls
Module 07 changes:
- Simplified model classes to minimal test fixtures
- Removed complex neural network teaching examples
- Focus purely on training infrastructure
Impact:
- Clearer learning progression
- Students understand each component's role
- Milestones become showcases of student work
- No magic containers hiding the data flow
Removed redundant test calls from all modules:
- Eliminated verbose if __name__ == '__main__': blocks
- Removed duplicate individual test calls
- Each module now simply calls test_module() directly
Changes made to all 9 modules:
- Module 01 (Tensor): Simplified from 16-line main block to 1 line
- Module 02 (Activations): Simplified from 13-line main block to 1 line
- Module 03 (Layers): Simplified from 17-line main block to 1 line
- Module 04 (Losses): Simplified from 20-line main block to 1 line
- Module 05 (Autograd): Simplified from 19-line main block to 1 line
- Module 06 (Optimizers): Simplified from 17-line main block to 1 line
- Module 07 (Training): Simplified from 16-line main block to 1 line
- Module 08 (DataLoader): Simplified from 17-line main block to 1 line
- Module 09 (Spatial): Simplified from 14-line main block to 1 line
Impact:
- Notebook-friendly: Tests run immediately in Jupyter environments
- No redundancy: test_module() already runs all unit tests
- Cleaner code: ~140 lines of redundant code removed
- Better for students: Simpler, more direct execution flow
Wrapped test code in if __name__ == '__main__': guards for:
- Module 02 (activations): 7 test calls protected
- Module 03 (layers): 7 test calls protected
- Module 04 (losses): 10 test calls protected
- Module 05 (autograd): 7 test calls protected
- Module 06 (optimizers): 8 test calls protected
- Module 07 (training): 7 test calls protected
- Module 09 (spatial): 5 test calls protected
Impact:
- All modules can now be imported cleanly without test execution
- Tests still run when modules are executed directly
- Clean dependency chain throughout the framework
- Follows Python best practices for module structure
This completes the fix for the entire module system. Modules can now
properly import from each other without triggering test code execution.
Major refactoring:
- Eliminated Variable class completely from autograd module
- Implemented progressive enhancement pattern with enable_autograd()
- All modules now use pure Tensor with requires_grad=True
- PyTorch 2.0 compatible API throughout
- Clean separation: Module 01 has simple Tensor, Module 05 enhances with gradients
- Fixed all imports and references across layers, activations, losses
- Educational clarity: students learn modern patterns from day one
The system now follows the principle: 'One Tensor class to rule them all'
No more confusion between Variable and Tensor - everything is just Tensor!
Major Accomplishments:
• Rebuilt all 20 modules with comprehensive explanations before each function
• Fixed explanatory placement: detailed explanations before implementations, brief descriptions before tests
• Enhanced all modules with ASCII diagrams for visual learning

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:

✅ 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.
- Removed 01_setup module (archived to archive/setup_module)
- Renumbered all modules: tensor is now 01, activations is 02, etc.
- Added tito setup command for environment setup and package installation
- Added numeric shortcuts: tito 01, tito 02, etc. for quick module access
- Fixed view command to find dev files correctly
- Updated module dependencies and references
- Improved user experience: immediate ML learning instead of boring setup
- 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.
- Update all test files to import from tinytorch.core.* instead of relative paths
- Consistent with rock solid foundation principle
- Tests now use stable package imports, not local module imports
- Ensures tests validate the actual exported package functionality
- Aligns with production usage patterns
