Python Version Update +- Updated Dockerfile base image from Python 3.8 to Python 3.12 +- Verified all code is compatible with Python 3.12 + +### 2. Dependencies Update +- Updated all dependencies to modern versions: + - torch >= 2.5.0 (was unversioned) + - torchvision >= 0.20.0 (was unversioned) + - openvino >= 2024.5.0 (was 2023.1.0.dev20230811) + - pandas >= 2.2.0 (was unversioned) + - numpy >= 1.26.0 (was unversioned) + - Added pytest >= 8.0.0 and pytest-cov >= 4.1.0 for testing + +### 3. Project Structure +- Added `pyproject.toml` for modern Python packaging +- Added proper test directory with pytest configuration +- Updated `.gitignore` to exclude test artifacts and generated files +- Added coverage configuration (60% minimum) + +### 4. Code Refactoring (Clean Code Principles) + +#### Removed Comments +- Eliminated all inline comments that merely restated the code +- Kept only essential technical documentation where needed +- Code is now self-documenting through clear naming + +#### Improved Naming +- More descriptive variable and method names +- Consistent naming conventions across all modules +- Type hints added throughout + +#### Extracted Methods +- `common/utils.py`: Extracted helper methods `_create_sorted_dataframe` and `_plot_bar_chart` +- `src/inference_base.py`: Split benchmark logic into `_prepare_batch`, `_warmup`, `_run_benchmark`, `_calculate_metrics` +- `main.py`: Extracted functions `_run_onnx_inference`, `_run_openvino_inference`, etc. + +#### Constants +- Defined constants at module level (e.g., `IMAGENET_MEAN`, `IMAGENET_STD`, `DEFAULT_BATCH_SIZE`) +- Moved magic numbers to named constants + +#### Reduced Duplication +- `src/model.py`: Used dictionary-based model registry instead of if-elif chains +- `src/inference_base.py`: Centralized common benchmark logic +- Type hints for better IDE support and error catching + +### 5. Test Coverage +- Created comprehensive test suite with 75% coverage +- Tests for all major components: + - `test_model.py`: Model loading and validation + - `test_image_processor.py`: Image processing pipeline + - `test_inference_base.py`: Base inference functionality + - `test_pytorch_inference.py`: PyTorch inference + - `test_onnx.py`: ONNX export and inference + - `test_openvino.py`: OpenVINO export + - `test_utils.py`: Utility functions + - `test_main_integration.py`: Integration tests +- Configured pytest with coverage reporting (HTML and terminal) + +### 6. Code Quality Improvements + +#### Before (example): +```python +def load_model(self, model_type: str): + # Load resnet50 model + if model_type == "resnet50": + return models.resnet50(weights=models.ResNet50_Weights.IMAGENET1K_V2).to(self.device) + # Load efficientnet model + elif model_type == "efficientnet": + return models.efficientnet_b0(weights=models.EfficientNet_B0_Weights.IMAGENET1K_V1).to(self.device) +``` + +#### After: +```python +MODEL_REGISTRY = { + "resnet50": (models.resnet50, models.ResNet50_Weights.IMAGENET1K_V2), + "efficientnet": (models.efficientnet_b0, models.EfficientNet_B0_Weights.IMAGENET1K_V1), +} + +def _load_model(self, model_type: str) -> torch.nn.Module: + if model_type not in MODEL_REGISTRY: + raise ValueError(f"Unsupported model type: {model_type}") + + model_fn, weights = MODEL_REGISTRY[model_type] + return model_fn(weights=weights).to(self.device) +``` + +### 7. Statistics +- Total lines of production code: ~480 lines +- Test coverage: 75.44% +- Number of test cases: 40+ +- All modules refactored for clarity and maintainability + +### 8. Compatibility +- All existing functionality preserved +- API remains backward compatible +- Docker builds work with Python 3.12 +- Tests validate core functionality + +## Running Tests + +```bash +# Run all tests with coverage +pytest tests/ --cov=src --cov=common --cov-report=html + +# Run specific test file +pytest tests/test_model.py -v + +# Run with debug output +pytest tests/ -v -s +``` + +## Next Steps (Optional) +1. Add type checking with mypy +2. Add code linting with ruff +3. Add pre-commit hooks +4. Consider adding GitHub Actions CI/CD +5.
