This is Part 1 of the federated learning (FL) demo project in Python using socket programming. In this part, a simple client-server app is created to send and receive text messages.
In Part 2, the server app will be extended to allow accepting multiple connections at the same time in addition to sending and receiving multiple messages within the same connection.
The project has the following files:
server.py: The server app. The server receives a text message from the client and replies with another text message.client.py: The client app which sends a text message trains to the server and receives a text response.
The project uses the PyGAD library for building and training the ML model. To install PyGAD, simply use pip to download and install the library from PyPI (Python Package Index). The library lives a PyPI at this page https://pypi.org/project/pygad.
For Windows, issue the following command:
pip install pygad
For Linux and Mac, replace pip by use pip3 because the library only supports Python 3.
pip3 install pygad
PyGAD is developed in Python 3.7.3 and depends on NumPy for creating and manipulating arrays and Matplotlib for creating figures. The exact NumPy version used in developing PyGAD is 1.16.4. For Matplotlib, the version is 3.1.0.
To get started with PyGAD, please read the documentation at Read The Docs https://pygad.readthedocs.io.
Start the project by running the server.py file from the terminal using the following command:
python server.py
For Mac/Linux, use python3 rather than python:
python3 server.py
After running the server, next is to run the client using the client.py script.
python client.py
For Mac/Linux, use python3 rather than python:
python3 client.py
