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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

<h3>Common Failure Patterns<a class="headerlink" href="#common-failure-patterns" title="Link to this heading">#</a></h3>
|
||
<p><strong>Import Errors:</strong></p>
|
||
<ul class="simple">
|
||
<li><p><strong>Problem</strong>: Module not found errors indicate missing exports</p></li>
|
||
<li><p><strong>Solution</strong>: Ensure modules are properly exported and environment is configured</p></li>
|
||
</ul>
|
||
<p><strong>Functionality Errors:</strong></p>
|
||
<ul class="simple">
|
||
<li><p><strong>Problem</strong>: Implementation doesn’t work as expected (shape mismatches, incorrect outputs)</p></li>
|
||
<li><p><strong>Debug approach</strong>: Use verbose testing to get detailed error information</p></li>
|
||
</ul>
|
||
<p><strong>Integration Errors:</strong></p>
|
||
<ul class="simple">
|
||
<li><p><strong>Problem</strong>: Modules don’t work together due to missing dependencies</p></li>
|
||
<li><p><strong>Solution</strong>: Verify prerequisite capabilities before testing advanced features</p></li>
