fedmind 0.1.9

Federated Learning research framework in your mind

FedMind

A simple and easy Federated Learning framework fit researchers' mind based on PyTorch.

Unlike other popular FL frameworks focusing on production, FedMind is designed for researchers to easily implement their own FL algorithms and experiments. It provides a simple and flexible interface to implement FL algorithms and experiments.

Installation

The package is published on PyPI under the name fedmind. You can install it with pip:

pip install fedmind

Usage

A configuration file in yaml is required to run the experiments. You can refer to the config.yaml as an example.

There are examples in the examples directory.

Make a copy of both the config.yaml and fedavg_demo.py to your own directory. You can run them with the following command:

python fedavg_demo.py

Here we recommend you to use the UV as a python environment manager to create a clean environment for the experiments.

After install uv, you can create a new environment and run a FedMind example with the following command:

uv init FL-demo
cd FL-demo

source .uv/bin/activate
uv add fedmind torchvision

wget https://raw.githubusercontent.com/Xiao-Chenguang/FedMind/refs/heads/main/examples/fedavg_demo.py
wget https://raw.githubusercontent.com/Xiao-Chenguang/FedMind/refs/heads/main/config.yaml

uv run python fedavg_demo.py

Features

• Simple: Easy to implement your own FL algorithms and experiments.
• PyTorch: Based on PyTorch, a popular deep learning framework.
• Multi-Platform: Support both Linux, macOS and Windows.
• CPU/GPU: Support both CPU and GPU training.
• Serial/Parallel: Support both serial and parallel training modes.
• Model Operation: Support model level operations like +, -, *, /.
• Reproducible: Reproduce your experiments with the configuration file and seed.

Serial/Parallel Training

This FL framework provides two client simulation modes depending on your resources:

• Parallel training speed up for powerful resources.
• Serialization for limited resources.

This is controlled by the parameter NUM_PROCESS which can be set in the config.yaml. Setting NUM_PROCESS to 0 will use the serialization mode where each client trains sequentially in same global round. Setting NUM_PROCESS > 0 will use the parallel mode where NUM_PROCESS workers consume the clients tasks in parallel. The recommended value for NUM_PROCESS is the number of CPU cores available.
