FiftyOne Documentation

The official FiftyOne documentation, available at fiftyone.ai.

FiftyOne uses Sphinx and Sphinx-Napoleon to generate its documentation and API reference from source.

Setup

In order to build the docs locally, you must:

  1. Be running Python 3.8 or 3.9 in a virtual environment

  2. Perform a developer install of fiftyone:

git clone https://github.com/voxel51/fiftyone
cd fiftyone

bash install.bash -d
  1. Add the path to your cloned fiftyone repository to your PYTHONPATH:
export PYTHONPATH=$PYTHONPATH:/path/to/fiftyone

Building

You can build the docs from source by running the generate_docs.bash script in this folder:

bash docs/generate_docs.bash

A couple noteable flags are supported:

  • -c performs a clean build by removing the docs/build folder beforehand. This is sometimes necessary to force updates, e.g. if you have edited a template and want to see how it affects pages whose source files haven't changed
  • -s will update static files only, i.e. custom.css and custom.js mentioned below
  • -f will perform a fast build, i.e. zoo and plugin docs will be skipped

Contributing

Main Content

The main content is located in the docs/source folder. The files are written in Sphinx RST format.

The API documentation is automatically generated from the Python source code, whose docstrings are written in Sphinx-Napoleon format.

Check out the existing patterns in the source files and you'll catch on.

FiftyOne Brain

For Voxel51 developers who are working with a source install of the FiftyOne Brain: the build script will automatically use your source install!

Teams SDK

Voxel51 developers can include Teams SDK-related components in their local docs build by including the -t flag:

bash docs/generate_docs.bash -t /path/to/fiftyone-teams

Style Guide

All documentation, including RST and all code samples embedded in it, must follow our style guide.

Note that pre-commit hooks will automatically enforce the whitespace-related components of our style when you commit changes.

Themes

Theme files are located in the docs/theme folder. However, you should prefer to make changes in the following locations instead of the theme itself whenever possible:

  • docs/source/_static contains custom.css and custom.js files, where any CSS overrides or custom JS should be added
  • docs/source/_templates contains HTML files (Jinja2 templates) that override theme templates of the same name. These should extend the theme templates - see the existing templates for how to do this. If you need to override part of the theme template that isn't conveniently marked as a block (and isn't a separate file that you can override), our convention is to add a block prefixed with custom_ to the theme template, then override that block locally

To work on the theme JavaScript (not custom.js), you will need to install a couple dependencies for the build process:

cd docs/theme
yarn install

A few commands are available:

  • yarn build bundles all JS files into the single file expected by the theme
  • yarn deploy builds and copies this file into the built documentation (which avoids the need to run generate_docs.bash again)
  • yarn watch re-runs yarn deploy whenever a JS source file changes
