Major fixes for complete training pipeline functionality: Core Components Fixed: - Parameter class: Now wraps Variables with requires_grad=True for proper gradient tracking - Variable.sum(): Essential for scalar loss computation from multi-element tensors - Gradient handling: Fixed memoryview issues in autograd and activations - Tensor indexing: Added __getitem__ support for weight inspection Training Results: - XOR learning: 100% accuracy (4/4) - network successfully learns XOR function - Linear regression: Weight=1.991 (target=2.0), Bias=0.980 (target=1.0) - Integration tests: 21/22 passing (95.5% success rate) - Module tests: All individual modules passing - General functionality: 4/5 tests passing with core training working Technical Details: - Fixed gradient data access patterns throughout activations.py - Added safe memoryview handling in Variable.backward() - Implemented proper Parameter-Variable delegation - Added Tensor subscripting for debugging access(https://claude.ai/code)
🧪 TinyTorch Integration Tests
⚠️ CRITICAL DIRECTORY - DO NOT DELETE
This directory contains 17 integration test files that verify cross-module functionality across the entire TinyTorch system. These tests represent significant development effort and are essential for:
- Module integration validation
- Cross-component compatibility
- Real-world ML pipeline testing
- System-level regression detection

📊 Test Coverage
These integration tests complement the inline tests in each module's *_dev.py files, providing comprehensive system validation with focus on:
- Real component integration (not mocks)
- Cross-module compatibility
- Realistic ML workflows (classification, seq2seq, transformers)
- Performance and scalability
