This section explains how to install the latest development version of FiftyOne from source.

The instructions below are for macOS and Linux systems. Windows users may need to make adjustments.

You will need:

• Python (3.5 or newer)
• Node.js - on Linux, we recommend using nvm to install an up-to-date version.
• Yarn - once Node.js is installed, you can install Yarn via npm install -g yarn
• On Linux, you will need at least the openssl and libcurl packages. On Debian-based distributions, you will need to install libcurl4 or libcurl3 instead of libcurl, depending on the age of your distribution. For example:

# Ubuntu 18.04
sudo apt install libcurl4 openssl

# Fedora 32
sudo dnf install libcurl openssl

We strongly recommend that you install FiftyOne in a virtual environment to maintain a clean workspace.

1. Clone the repository:

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

2. Run the installation script:

bash install.bash

3. If you want to use the fiftyone.brain package, you will need to install it separately after installing FiftyOne:

pip install --index https://pypi.voxel51.com fiftyone-brain

Installing FiftyOne from source includes an ETA lite installation, which should be sufficient for most users. If you want a full ETA installation, or wish to otherwise customize your ETA installation, see here.

If you would like to contribute to FiftyOne, you should perform a developer installation using the -d flag of the install script:

bash install.bash -d

To upgrade an existing source installation to the bleeding edge, simply pull the latest develop branch and rerun the install script:

git checkout develop
git pull
bash install.bash [-d]

See the docs guide for information on building and contributing to the documentation.

You can uninstall FiftyOne as follows:

pip uninstall fiftyone fiftyone-brain fiftyone-db fiftyone-gui
