ai2-tango 0.7.0

A library for choreographing your machine learning research.

AI2 Tango replaces messy directories and spreadsheets full of file versions by organizing experiments into discrete steps that can be cached and reused throughout the lifetime of a research project.

Installation

ai2-tango requires Python 3.7 or later.

Installing with conda

ai2-tango is available on conda-forge. You can install just the base package with

conda install tango -c conda-forge

You can pick and choose from the integrations with one of these:

conda install tango-datasets -c conda-forge
conda install tango-pytorch_lightning -c conda-forge
conda install tango-torch -c conda-forge
conda install tango-wandb -c conda-forge

You can also install everything:

conda install tango-all -c conda-forge

Even though ai2-tango itself is quite small, installing everything will pull in a lot of dependencies. Don't be surprised if this takes a while!

Installing with pip

ai2-tango is available on PyPI. Just run

pip install ai2-tango

To install with a specific integration, such as torch for example, run

pip install 'ai2-tango[torch]'

To install with all integrations, run

pip install 'ai2-tango[all]'

Installing from source

To install ai2-tango from source, first clone the repository:

git clone https://github.com/allenai/tango.git
cd tango

Then run

pip install -e '.[all]'

To install with only a specific integration, such as torch for example, run

pip install -e '.[torch]'

Or to install just the base tango library, you can run

pip install -e .

Checking your installation

Run

tango info

to check your installation.

Docker image

You can build a Docker image suitable for tango projects by using the official Dockerfile as a starting point for your own Dockerfile, or you can simply use one of our prebuilt images as a base image in your Dockerfile. For example:

# Start from a prebuilt tango base image.
# You can choose the right tag from the available options here:
# https://github.com/allenai/tango/pkgs/container/tango/versions
FROM ghcr.io/allenai/tango:cuda11.3

# Install your project's additional requirements.
COPY requirements.txt .
RUN /opt/conda/bin/pip install --no-cache-dir -r requirements.txt

# Install source code.
# This instruction copies EVERYTHING in the current directory (build context),
# which may not be what you want. Consider using a ".dockerignore" file to
# exclude files and directories that you don't want on the image.
COPY . .

Make sure to choose the right base image for your use case depending on the version of tango you're using and the CUDA version that your host machine supports. You can see a list of all available image tags on GitHub.

FAQ

Why is the library named Tango?

The motivation behind this library is that we can make research easier by composing it into well-defined steps. What happens when you choreograph a number of steps together? Well, you get a dance. And since our team's leader is part of a tango band, "AI2 Tango" was an obvious choice!
