Flower (flwr) is a framework for building federated learning systems. The
design of Flower is based on a few guiding principles:
-
Customizable: Federated learning systems vary wildly from one use case to another. Flower allows for a wide range of different configurations depending on the needs of each individual use case.
-
Extendable: Flower originated from a research project at the University of Oxford, so it was built with AI research in mind. Many components can be extended and overridden to build new state-of-the-art systems.
-
Framework-agnostic: Different machine learning frameworks have different strengths. Flower can be used with any machine learning framework, for example, PyTorch, TensorFlow, Hugging Face Transformers, PyTorch Lightning, MXNet, scikit-learn, JAX, TFLite, Pandas for federated analytics, or even raw NumPy for users who enjoy computing gradients by hand.
-
Understandable: Flower is written with maintainability in mind. The community is encouraged to both read and contribute to the codebase.

Federated Learning Tutorial
Flower's goal is to make federated learning accessible to everyone. This series of tutorials introduces the fundamentals of federated learning and how to implement them in Flower.
-
An Introduction to Federated Learning
(or open the Jupyter Notebook)
-
Using Strategies in Federated Learning
-
Building Strategies for Federated Learning
-
Custom Clients for Federated Learning
Stay tuned, more tutorials are coming soon. Topics include Privacy and Security in Federated Learning, and Scaling Federated Learning.

Flower Baselines
Flower Baselines is a collection of community-contributed experiments that reproduce the experiments performed in popular federated learning publications. Researchers can build on Flower Baselines to quickly evaluate new ideas:
- FedAvg:
- FedBN: Federated Learning on non-IID Features via Local Batch Normalization:
- Adaptive Federated Optimization:
