XAIN is an open source framework for federated learning.
The XAIN project is building a privacy layer for machine learning so that AI projects can meet compliance such as GDPR and CCPA. The approach relies on Federated Learning as enabling technology that allows production AI applications to be fully privacy compliant.
Federated Learning also enables different use-cases that are not strictly privacy related such as connecting data lakes, reaching higher model performance in unbalanced datasets and utilising AI models on the edge.
This repository contains the source code for running the Coordinator. The Coordinator is the component of Federated Learning that selects the Participants for training and aggregates the models using federated averaging.
The Participants run in a separate environment than the Coordinator and connect to it using an SDK. You can find here the source code for it.
XAIN requires Python 3.6.4+. To install the
xain-fl package just run:
$ python -m pip install xain-fl
Install from source
Clone this repository:
git clone https://github.com/xainag/xain-fl.git
Install this project with the
dev profile (NOTE: it is
recommended to install the project in a virtual environment):
cd xain-fl pip install -e '.[dev]'
Verify the installation by running the tests
Building the Documentation
The project documentation resides under
docs/. To build the documentation
$ cd docs/ $ make docs
The generated documentation will be under
docs/_build/html/. You can open the
root of the documentation by opening
docs/_build/html/index.html on your
favorite browser or simply run the command:
$ make show
Running the Coordinator locally
To run the Coordinator on your local machine, you can use the
# If you have installed the xain_fl package, # the `coordinator` command should be directly available coordinator --config configs/example-config.toml # otherwise the coordinator can be started by executing the # `xain_fl` package: python xain_fl --config configs/example-config.toml
Run the Coordinator from a Docker image
There are two docker-compose files, one for development and one for release.
To run the coordinator's development image, first build the Docker image:
$ docker build -t xain-fl-dev -f Dockerfile.dev .
Then run the image, mounting the directory as a Docker volume:
$ docker run -v $(pwd):/app -v '/app/xain_fl.egg-info' xain-fl-dev coordinator
The command above uses a default configuration but you can also use a custom config file:
For instance, if you have a
./custom_config.toml file that you'd
like to use, you can mount it in the container and run the coordinator
docker run \ -v $(pwd)/custom_config.toml:/custom_config.toml \ -v $(pwd):/app \ -v '/app/xain_fl.egg-info' \ xain-fl-dev \ coordinator --config /custom_config.toml
To run the coordinator's release image, first build it:
$ docker build -t xain-fl .
And then run it (this example assumes you'll want to use the default port):
$ docker run -p 50051:50051 xain-fl
The coordinator needs a storage service that provides an AWS S3
API. For development, we use
minio. We provide
files that start coordinator container along with a
and pre-populate the appropriate storage buckets.
To start both the coordinator and the
minio service use:
docker-compose -f docker-compose-dev.yml up
It is also possible to only start the storage service:
docker-compose -f docker-compose-dev.yml up minio-dev initial-buckets
$ docker-compose up
