MONAI Deploy App SDK

MONAI Deploy App SDK offers a framework and associated tools to design, develop and verify AI-driven applications in the healthcare imaging domain.

Features

• Build medical imaging inference applications using a flexible, extensible & usable Pythonic API
• Easy management of inference applications via programmable Directed Acyclic Graphs (DAGs)
• Built-in operators to load DICOM data to be ingested in an inference app
• Out-of-the-box support for in-proc PyTorch based inference
• Easy incorporation of MONAI based pre and post transformations in the inference application
• Package inference application with a single command into a portable MONAI Application Package
• Locally run and debug your inference application using App Runner

User Guide

User guide is available at docs.monai.io.

Installation

To install the current release, you can simply run:

pip install monai-deploy-app-sdk  # '--pre' to install a pre-release version.

Prerequisites

• This SDK depends on NVIDIA Holoscan SDK for its core implementation as well as its CLI, hence inherits its prerequisites, e.g. Ubuntu 22.04 with glibc 2.35 on X86-64 and NVIDIA dGPU drivers version 535 or above.
• CUDA 12.2 or above is required along with a supported NVIDIA GPU with at least 8GB of video RAM.
• If inference is not used in an example application and a GPU is not installed, at least CUDA 12 runtime is required, as this is one of the requirements of Holoscan SDK. In addition, the LIB_LIBRARY_PATH must be set to include the installed shared library, e.g. in a Python 3.10 env, export LD_LIBRARY_PATH=`pwd`/.venv/lib/python3.10/site-packages/nvidia/cuda_runtime/lib:$LD_LIBRARY_PATH
• Python: 3.9 to 3.12

Getting Started

Getting started guide is available at here.

pip install monai-deploy-app-sdk  # '--pre' to install a pre-release version.

# Clone monai-deploy-app-sdk repository for accessing examples.
git clone https://github.com/Project-MONAI/monai-deploy-app-sdk.git
cd monai-deploy-app-sdk

# Install necessary dependencies for simple_imaging_app
pip install matplotlib Pillow scikit-image

# Execute the app locally
python examples/apps/simple_imaging_app/app.py -i examples/apps/simple_imaging_app/input/brain_mr_input.jpg -o output

# Package app (creating MAP Docker image), using `-l DEBUG` option to see progress.
# Also please note that postfix will be added to user supplied tag for identifying CPU architecture and GPU type etc.
monai-deploy package examples/apps/simple_imaging_app -c examples/apps/simple_imaging_app/app.yaml -t simple_app:latest --platform x64-workstation -l DEBUG

# Run the app with docker image and an input file locally
## Copy a test input file to 'input' folder
mkdir -p input && rm -rf input/*
cp examples/apps/simple_imaging_app/input/brain_mr_input.jpg input/
## Launch the app
monai-deploy run simple_app-x64-workstation-dgpu-linux-amd64:latest -i input -o output
