Overview

Installation

git clone https://github.com/lishenghui/blades
cd blades
pip install -v -e .
# "-v" means verbose, or more output
# "-e" means installing a project in editable mode,
# thus any local modifications made to the code will take effect without reinstallation.

cd blades/blades
python train.py file ./tuned_examples/fedsgd_cnn_fashion_mnist.yaml

Blades internally calls ray.tune; therefore, the experimental results are output to its default directory: ~/ray_results.

Experiment Results

Cluster Deployment

To run blades on a cluster, you only need to deploy Ray cluster according to the official guide.
