The application pipeline shall use pure MONAI Deploy App SDK APIs and operators. + +- The MONAI Deploy application pipeline should include all steps as described above in the *Pipeline Integration Example* section. +- We should parse and implement the preprocessing transforms from the bundle's metadata. +- Ensure configurations are loaded from the [inference.json](tools/pipeline-generator/phase_1/spleen_ct_segmentation/configs/inference.json) file at runtime and not hard coded. +- The input is a directory path; the directory would contain multiple files and the application shall proess all files. +- The output from our application pipeline should be the same as the expected output, same directory structure and data format. We should also compare the application output to the expected output. + +Input (NIfTI): /home/vicchang/Downloads/Task09_Spleen/Task09_Spleen/imagesTs +Model: tools/pipeline-generator/phase_1/spleen_ct_segmentation/models/model.ts +Expected Output: tools/pipeline-generator/phase_1/spleen_ct_segmentation/eval + + +Note: we may need to modify the existing [monai_bundle_inference_operator](monai/deploy/operators/monai_bundle_inference_operator.py) to support loading from a directory instead of a ZIP file.

Ensure to keep existing ZIP file support. + +Note: refer to [samples](/home/vicchang/sc/github/monai/monai-deploy-app-sdk/examples) for how to compose a MONAI Deploy application. Reuse all operators if possible. For example, if there are Nifti loaders, then do not recreate one. + +`For this phase, assume we use pure MONAI Deploy App SDK end-to-end.` + +### Phase 2 + +Create a CLI with a command to list available models from https://huggingface.co/MONAI. It should pull all available models using HuggingFace Python API at runtime. +However, a YAML config file should have a list of endpoints to scan the models from, we will start with https://huggingface.co/MONAI but later add models listed in section Phase 7. +The CLI should be able to support other commands later. For example, in 0.2, we need to add a command to generate an application and 0.3 to run the generated application. + +```bash +pg list +``` + +Note: this new project solution shall be independent from Phase 1. This project shall use poetry for dependency management and include unit test. + +### Phase 3 + +* Generate a MONAI Deploy-based Pipeline on selected a select MONAI Bundle from https://huggingface.co/MONAI.

+ │ ├── model.ts + │ └── model.pt + └── docs/ + └── README.md +``` + +## Usage Example + +```bash +# Generate application for spleen segmentation +pg gen MONAI/spleen_ct_segmentation --output my_app + +# Generate with custom class name +pg gen MONAI/lung_nodule_ct_detection --output lung_app --app-name LungDetectorApp + +# Force overwrite existing directory +pg gen MONAI/example_spleen_segmentation --output test_app --force +``` + +## Limitations and Assumptions + +1. **Bundle Structure**: Assumes standard MONAI Bundle structure +2. **Model Format**: Prioritizes TorchScript (.ts) over other formats +3. **Metadata**: Falls back to defaults if metadata.json missing +4. **Organ Detection**: Limited to common organ names +5. **Task Support**: Optimized for segmentation tasks + +## Dependencies Used + +- **jinja2**: Template engine for code generation +- **huggingface-hub**: Already present for model downloading +- Existing Pipeline Generator infrastructure + +## Next Steps + +This implementation enables: +- Phase 4: `run` command to execute generated applications +- Phase 5: `package` command using holoscan-cli +- Phase 6: Holoscan SDK pipeline generation option + +## Success Criteria Met + +1. ✅ Generate app.py with end-to-end MONAI Deploy pipeline +2. ✅ Generate app.yaml with configurations +3. ✅ Download all model files from HuggingFace +4. ✅ Use Jinja2 for main code templates +5. ✅ Use Pydantic/dataclasses for configuration models +6. ✅ YAML library for configuration generation +7. ✅ Output structure matches specification \ No newline at end of file diff

+ +If you have the Pipeline Generator installed globally: + +```bash +pg run . --input /path/to/input --output /path/to/output +``` + +#### Option 3: Manual Execution + +```bash +# If using virtual environment (recommended) +# Activate it first: +# source venv/bin/activate # Linux/Mac +# venv\Scripts\activate # Windows + +# Run the application +python app.py -i /path/to/input -o /path/to/output

- Introduced ImageOverlayWriter for blending segmentation masks onto RGB images and saving as PNG. - Updated ImageDirectoryLoader to support channel-first output configuration and improved file searching logic. - Adjusted documentation and examples to reflect the transition from Poetry to uv for command execution. - Updated various configuration files and templates to accommodate new features and dependencies.

00:00:00 2001 From: Victor Chang Date: Tue, 12 Aug 2025 14:43:56 -0700 Subject: [PATCH 04/19] Add support for Llama3-VILA-M3 models with new operators - Introduced PromptsLoaderOperator to read prompts from a YAML file and emit them sequentially. - Added Llama3VILAInferenceOperator for running inference with the Llama3-VILA-M3-3B model, supporting multiple output types. - Created VLMResultsWriterOperator to write results to disk based on the specified output type. - Updated configuration files and templates to integrate new operators and support custom input/output types. - Added unit tests for the new operators to ensure functionality and correctness.

Introduced a new GitHub Actions workflow for testing the pipeline generator, including steps for setting up Python 3.10, installing dependencies, and running tests. - Updated the version of the pipeline-generator package from 0.1.0 to 1.0.0 in the uv.lock file. - Refactored import statements and improved code formatting in various files for better readability and consistency.

structure and improve readability. - Refined the NiftiDataLoader to ensure proper handling of various dimensionalities and added logging for unexpected shapes. - Enhanced the pipeline generator to include new operators and improved the handling of output types. - Cleaned up whitespace and formatting inconsistencies across multiple files for better code clarity. - Removed deprecated test files related to GenericDirectoryScanner and VLM operators to maintain a clean codebase.
