AST-Based Code Analysis + +Instead of just parsing `config.json`, the `ArchitectureScanner` uses Python's `ast` module to analyze the actual model code (`modeling_*.py`). This ensures: +- Discovery of custom layer classes even if not in config +- Understanding of inheritance patterns +- Extraction of layer-specific parameters + +### 2. Pattern Matching for Support + +The `CapabilityRegistry` uses pattern matching (regex) to determine if a layer is supported: +```python +LLAMA_PATTERNS = [".*LlamaAttention.*", ".*LlamaRMSNorm.*"] +``` +This allows flexible matching across model variants without exact name matching. + +### 3. Support Levels and Fallbacks + +Four support levels provide granularity: +- **FULL**: Complete NPU support +- **PARTIAL**: NPU support with limitations +- **FALLBACK**: Use CPU/GPU fallback +- **UNSUPPORTED**: No implementation available + +Fallback strategies: +- **CPU_FALLBACK**: Run on CPU +- **DECOMPOSE**: Break into simpler operations +- **APPROXIMATE**: Use approximate computation +- **CUSTOM_NEEDED**: Requires new implementation + +### 4. Plugin Architecture + +The extensibility framework uses: +- **Registries** for dynamic operator/handler registration +- **Extension points** for pipeline hooks +- **Auto-discovery** for loading extensions from directories + +### 5. Skeleton Generation + +The `generate_operator_skeleton()` function creates starter implementations with: +- Proper class structure +- Method stubs with docstrings +- Example MLIR generation template +- Comments guiding implementation + +--- + +## File Structure + +``` +iron/model_convert/ +├── __init__.py # Package exports (all classes) +├── README.md # Core converter documentation +├── EXTENSIBILITY_GUIDE.md # Gap analysis & extensibility guide +├── usage_example.py # Usage examples +│ +├── config_adapter.py # HF config parsing +├── weight_mapper.py # Weight transformation +├── shape_manager.py # NPU shape calculations +├── operator_factory.py # NPU operator creation +├── layer_builder.py # Layer construction +├── model_assembler.py # Model orchestration +├── converter.py # Main converter API +│ +├── architecture_scanner.py # NEW: Model code analysis +├── capability_registry.py # NEW: Support tracking +├── gap_analyzer.py # NEW: Gap identification +└── extensibility.py # NEW: Plugin system +``` + +--- + +## Usage Examples + +### Quick Check +```python +from iron.model_convert import quick_check + +if quick_check("meta-llama/Llama-2-7b-hf"): + print("Model is likely supported") +else: + print("Model needs review") +``` + +### Generate Gap Report +```python +from iron.model_convert import generate_gap_report + +report = generate_gap_report("path/to/Qwen3.5-27B") +print(f"Support: {report.support_percentage:.1f}%") +print(f"Feasibility: {report.conversion_feasibility}") +``` + +### Register Custom Operator +```python +from iron.model_convert import quick_register_operator + +quick_register_operator( + name="CustomAttention", + module_patterns=["mymodel.CustomAttention"], + category="attention", + support_level="partial", +) +``` + +### Generate Operator Skeleton +```python +from iron.model_convert import generate_operator_skeleton + +skeleton = generate_operator_skeleton( + operator_name="SlidingWindowAttention", + output_path="./extensions/sliding_window.py", +) +``` + +--- + +## Testing Recommendations + +To fully test the implementation: + +1. **Architecture Scanner Test** + ```python + from iron.model_convert import ArchitectureScanner + scanner = ArchitectureScanner("path/to/model") + requirements = scanner.scan() + ``` + +2. **Gap Analysis Test** + ```python + from iron.model_convert import GapAnalyzer + analyzer = GapAnalyzer() + report = analyzer.analyze(requirements) + ``` + +3. **Extensibility Test** + ```python + from iron.model_convert import ExtensionLoader + loader = ExtensionLoader(search_paths=["./extensions"]) + results = loader.load_all() + ``` + +--- + +## Dependencies + +The model converter depends on: +- `aie` (mlir-aie) -
