Its ambitions are as follows: - Developing a community of academic, industrial and clinical researchers collaborating on a common foundation; - Creating state-of-the-art, end-to-end training workflows for healthcare imaging; - Providing researchers with the optimized and standardized way to create and evaluate deep learning models. ## Features > _Please see [the technical highlights](https://monai.readthedocs.io/en/latest/highlights.html) and [What's New](https://monai.readthedocs.io/en/latest/whatsnew.html) of the milestone releases._ - flexible pre-processing for multi-dimensional medical imaging data; - compositional & portable APIs for ease of integration in existing workflows; - domain-specific implementations for networks, losses, evaluation metrics and more; - customizable design for varying user expertise; - multi-GPU multi-node data parallelism support. ## Requirements MONAI works with the [currently supported versions of Python](https://devguide.python.org/versions), and depends directly on NumPy and PyTorch with many optional dependencies. * Major releases of MONAI will have dependency versions stated for them. The current state of the `dev` branch in this repository is the unreleased development version of MONAI which typically will support current versions of dependencies and include updates and bug fixes to do so. * PyTorch support covers [the current version](https://github.com/pytorch/pytorch/releases) plus three previous minor versions. If compatibility issues with a PyTorch version and other dependencies arise, support for a version may be delayed until a major release. * Our support policy for other dependencies adheres for the most part to [SPEC0](https://scientific-python.org/specs/spec-0000), where dependency versions are supported where possible for up to two years. Discovered vulnerabilities or defects may require certain versions to be explicitly not supported. * See the `requirements*.txt` files for dependency version information. ## Installation To install [the current release](https://pypi.org/project/monai/), you can simply run: ```bash pip install monai ``` Please refer to [the installation guide](https://monai.readthedocs.io/en/latest/installation.html) for other installation options. ## Getting Started [MedNIST demo](https://colab.research.google.com/github/Project-MONAI/tutorials/blob/main/2d_classification/mednist_tutorial.ipynb) and [MONAI for PyTorch Users](https://colab.research.google.com/github/Project-MONAI/tutorials/blob/main/modules/developer_guide.ipynb) are available on Colab. Examples and notebook tutorials are located at [Project-MONAI/tutorials](https://github.com/Project-MONAI/tutorials). Technical documentation is available at [monai.readthedocs.io](https://monai.readthedocs.io). ## Docker The MONAI Docker image is available from [Dockerhub](https://hub.docker.com/r/projectmonai/monai), tagged as `latest` for the latest state of `dev` or with a release version. A slimmed down image can also be built locally using `Dockerfile.slim`, see that file for instructions. To get started with the latest MONAI, use `docker run -ti --rm --gpus all projectmonai/monai:latest /bin/bash`. ## Citation If you have used MONAI in your research, please cite us!
