Installation on Linux

This documentation is to help you install and be able to deploy a Domain Node on Ubuntu Linux, with a version of 20.04.03 or newer, in the simplest way possible.

Note

Do you use a different distribution other than Ubuntu? Don’t worry, just replace the apt & apt-get with your package manager.

  1. Launching a Terminal Instance

We will use the Linux Terminal to install all the prerequisites and launch the domain. A quick way to launch the terminal is by pressing Ctrl+Alt+T. Let’s go!

  1. Installing Python 3.9

We’ll be working with Python 3.9 or newer. To check if you have it installed, you may run:

python3 --version

Your output should looks something like Python 3.x.y where x>=9.

If you don’t have the correct version of Python, installing it is as easy as running the following:

sudo apt update
sudo apt install python3.9
python3 --version
  1. Installing and using Pip

Pip is the most widely used package installer for Python and will help us to install the required dependencies MUCH easier. You can install it by running the following:

python -m ensurepip --upgrade

If you already have it installed, you can check to make sure it’s the latest version by running:

python -m pip install --upgrade pip

Your output should looks something like Requirement already satisfied: pip in <package-dir>.

  1. Conda and setting up a virtual environment

Conda is a package manager that helps you to easily install a lot of data science and machine learning packages, but also to create a separated environment when a certain set of dependencies need to be installed. To install Conda, you can:

  1. Download the Anaconda installer.

  2. Run the following code, modifying it depending on where you downloaded the installer (e.g. ~/Downloads/):

    bash ~/Downloads/Anaconda3-2020.02-Linux-x86_64.sh
    

    Note

    Please note that the naming might be different given it could be a newer version of Anaconda.

  3. Create a new env specifying the Python version (we recommend Python 3.8/3.9) in the terminal:

    conda create -n syft_env python=3.9
    conda activate syft_env
    
  4. To exit, you can run:

    conda deactivate
    
  1. Install Jupyter Notebook

A very convenient way to interact with a deployed node is via Python, using a Jupyter Notebook. You can install it by running:

pip install jupyter-notebook

If you encounter issues, you can also install it using Conda:

conda install -c conda-forge notebook

To launch the Jupyter Notebook, you can run the following in your terminal:

jupyter notebook
  1. Installing and configuring Docker

Docker is a framework which allows us to separate the infrastructure needed to run PySyft in an isolated environment called a container which you can use off the shelf, without many concerns. If it sounds complicated, please don’t worry, we will walk you through all steps, and you’ll be done in no time! Additionally, we will also use Docker Composite V2, which allows us to run multi-container applications.

  1. Install Docker:

    sudo apt-get upgrade docker & docker run hello-world
    
  2. Install Docker Composite V2 as described here.

  3. Run the below command to verify the install:

    docker compose version
    

    You should see somthing like Docker Compose version 2.x.y in the output when runnning the above command.

  4. If you see something else, go through the instructions here or if you are using Linux, you can try to do:

    mkdir -p ~/.docker/cli-plugins
    curl -sSL https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
    chmod +x ~/.docker/cli-plugins/docker-compose
    
  5. Also, make sure you can run without sudo:

    echo $USER //(should return your username)
    sudo usermod -aG docker $USER
    
  1. Install PySyft and Hagrid

The hardest part is done! To install the OpenMined stack that you need in order to deploy a node, please run:

pip install syft hagrid

PySyft is a library which contains the tools to run privacy preserving machine learning. Hagrid is a commandline tool that speeds up the deployment of PyGrid, the provider of a peer-to-peer network of data owners and data scientists who can collectively train AI model using Syft.

  1. Launch the Domain Node

Congrats for making it this far! You only have one final step remaining, before you unleash the power of Hagrid! The final step is to launch a domain node, which is as easy as:

hagrid launch <name_of_domain>

To stop the running domain, run:

hagrid land <name_of_domain>

But before stopping it, you can go to localhost:8081 in your browser to actually interact with the PyGrid Admin UI, where you can manage as a Data Owner your datasets, as well as incoming requests from data scientist. You can log in using the following credentials:

info@openmined.org

changethis

Now you’re all set up to fully start using PySyft!
