Overview

Instructions on setting up and using a Python repository.

Usage

Activate the virtual environment (see below for instructions) and follow the instructions provided by the README.

Development

Activate the virtual environment, and follow the instructions:

Setup

This is only needed to be done once before doing anything.

Install Git if it has not already been installed: Git

Windows: Use the Windows Credential Manager if you do not want to use SSH keys

Install Python 3.8 if it has not already been installed: Welcome to Python.org

The version matters, do not use any other version! 3.8.n, n is not important

Find the Git link in the repository:

In GitHub, in the repository front page, click on the green button on the right with <> Code
In the dropdown:
1. Windows: Use the HTTPS link
2. Linux: Use the SSH link

Clone repository to local:

git clone [repository link]
cd [repository name]
git submodule update --init --recursive --remote

Create and activate the virtual environment (see below for instructions).

Update pip: pip install --upgrade pip

Install the required Python packages: Instructions found in the README.

Often you will see: pip install -r requirements.txt . Do NOT blindly run this command! Every repository is different in how to install packages.

Virtual Environment

The Python virtual environment is a mechanism to isolate Python environments between projects. This is especially useful for dependencies that require specific versions of Python and/or packages.

Creation and Deletion

Autonomy uses venv as the name for virtual environments. Do not use any other name! If you already have a virtual environment with a different name, please delete the directory from your local repository.

Create the virtual environment in the top level directory of the local repository: python3 -m venv venv/

Activate

Activate the environment:

Windows command prompt: venv\Scripts\activate.bat
Windows Powershell: venv\Scripts\Activate.ps1
Linux and MacOS: source venv/bin/activate

(venv) is now prefixed, which means you are now in the environment.

Ensure the correct version of Python is installed: python --version

Should be Python 3.8

Deactivate

When you are done, deactivate the environment if you are using the same terminal for another repository:

Windows command prompt: venv\Scripts\deactivate.bat
Windows Powershell, Linux, and MacOS: deactivate
