All modules now follow consistent formatting standards for release.
This commit implements a comprehensive quality assurance system and removes
outdated backup files from the repository.
## Release Check Workflow
Added GitHub Actions workflow for systematic release validation:
- Manual-only workflow (workflow_dispatch) - no automatic PR triggers
- 6 sequential quality gates: educational, implementation, testing, package, documentation, systems
- 13 validation scripts (4 fully implemented, 9 stubs for future work)
- Comprehensive documentation in .github/workflows/README.md
- Release process guide in .github/RELEASE_PROCESS.md
Implemented validators:
- validate_time_estimates.py - Ensures consistency between LEARNING_PATH.md and ABOUT.md files
- validate_difficulty_ratings.py - Validates star rating consistency across modules
- validate_testing_patterns.py - Checks for test_unit_* and test_module() patterns
- check_checkpoints.py - Recommends checkpoint markers for long modules (8+ hours)
## Pedagogical Improvements
Added checkpoint markers to Module 05 (Autograd):
- Checkpoint 1: After computational graph construction (~40% progress)
- Checkpoint 2: After automatic differentiation implementation (~80% progress)
- Helps students track progress through the longest foundational module (8-10 hours)
## Codebase Cleanup
Removed 20 legacy *_dev.py files across all modules:
- Confirmed via export system analysis: only *.py files (without _dev suffix) are used
- Export system explicitly reads from {name}.py (see tito/commands/export.py line 461)
- All _dev.py files were outdated backups not used by the build/export pipeline
- Verified all active .py files contain current implementations with optimizations
This cleanup:
- Eliminates confusion about which files are source of truth
- Reduces repository size
- Makes development workflow clearer (work in modules/XX_name/name.py)
## Formatting Standards Documentation
Documents formatting and style standards discovered through systematic
review of all 20 TinyTorch modules.
### Key Findings
Overall Status: 9/10 (Excellent consistency)
- All 20 modules use correct test_module() naming
- 18/20 modules have proper if __name__ guards
- All modules use proper Jupytext format (no JSON leakage)
- Strong ASCII diagram quality
- All 20 modules missing 🧪 emoji in test_module() docstrings
### Standards Documented
1. Test Function Naming: test_unit_* for units, test_module() for integration
2. if __name__ Guards: Immediate guards after every test/analysis function
3. Emoji Protocol: 🔬 for unit tests, 🧪 for module tests, 📊 for analysis
4. Markdown Formatting: Jupytext format with proper section hierarchy
5. ASCII Diagrams: Box-drawing characters, labeled dimensions, data flow arrows
6. Module Structure: Standard template with 9 sections
### Quick Fixes Identified
- Add 🧪 emoji to test_module() in all 20 modules (~5 min)

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
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 ✓
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.
