Basic Tutorial for XFL

We provide two methods for users to start running with XFL: via docker or conda.

Prerequisites

  • Python：3.9

  • OS：MacOS，Linux（most distributions supported, CentOS 7 in this tutorial）

  • CPU/Memory：8 cores and 16G memory is recommended as a minimum configuration

  • Redis

Clone the repository

git clone https://github.com/paritybit-ai/XFL
cd XFL

Using docker

Run redis-server

# Get the redis image
docker pull redis:7.0.3

# start a redis server, and make sure that port 6379 is open
docker run --name my_redis -p 6379:6379 -d redis:7.0.3

Start with XFL

Run the XFL image as a container

# pull the image
docker pull basebit/xfl:1.2.0

# start with XFL
docker run -it --entrypoint /bin/bash \
--network container:my_redis \
-v $PWD/demo:/opt/app/xfl/demo \
-v /opt/dataset:/opt/dataset \
-v /opt/config:/opt/config \
-v /opt/log:/opt/log \
-v /opt/checkpoints:/opt/checkpoints \
basebit/xfl:1.4.0

Quick start demo

Running inside docker contrainer

cd demo/vertical/logistic_regression/2party
sh run.sh

Using Conda

Environment Preparation

It is recommended to use anaconda to create a virtual environment.

conda create -n xfl python=3.9.7

conda activate xfl

Install redis and other dependencies

# Ubuntu
apt install redis-server

# CentOS
yum install epel-release
yum install redis

# MacOS
brew install redis
brew install coreutils

install python dependencies

# update pip
pip install -U pip

# install dependencies
pip install -r requirements.txt

Quick start demo

Running in standalone mode

# set permission
sudo chmod 755 /opt

# enter the project directory
cd demo/vertical/logistic_regression/2party

# activate the virtual environment
conda activate xfl

# start redis-server (skip if it is already run)
redis-server & # for Ubuntu and MacOS

systemctl start redis # for CentOS

# start running the demo
sh run.sh

Demonstration tutorial

We provide various examples in the demo directory of the project.

In each subdirectory, an executable script for demonstration is provided. For example, the following commands run the vertical logistic regression (two parties)

cd demo/vertical/logistic_regression/2party

sh run.sh
  • The read and write permissions to the \opt directory are required when running with the default configuration. If the permission cannot be obtained, one should modify the configuration under the corresponding subdirectory.
  • A JOB_ID will be automatically assigned to the task after it is running. According to this JOB_ID, the output and log files of the task can be obtained.
  • After tasks are executed, the log INFO: All Stage Successful. will be printed, indicating that all tasks were executed successfully.

A successfully executed vertical logistic regression (two parties) produces the following files:

/opt
├── checkpoints         # model path
│   ├── ...
│   └── 4               # [JOB_ID]
│       ├── node-1      # output directory for node-1 (model file included)
│       │   ├── vertical_logistic_regression_guest.pt
│       │   └── ...     
│       └── node-2      # output directory for node-2 (model file included)
│           ├── vertical_logistic_regression_host.pt
│           └── ...     
└── log
    └── 4               # [JOB_ID]
        └── xfl.log     # log file

After the task is completed, one can clean up residual processes with following script.

# clean up residual processes
sh stop.sh
