What is Squirrel?

Squirrel is a Python library that enables ML teams to share, load, and transform data in a collaborative, flexible, and efficient way.

  1. SPEED: Avoid data stall, i.e. the expensive GPU will not be idle while waiting for the data.

  2. COSTS: First, avoid GPU stalling, and second allow to shard & cluster your data and store & load it in bundles, decreasing the cost for your data bucket cloud storage.

  3. FLEXIBILITY: Work with a flexible standard data scheme which is adaptable to any setting, including multimodal data.

  4. COLLABORATION: Make it easier to share data & code between teams and projects in a self-service model.

Stream data from anywhere to your machine learning model as easy as:

it = (Catalog.from_plugins()["imagenet"].get_driver()
      .get_iter("train")
      .map(lambda r: (augment(r["image"]), r["label"]))
      .batched(100))

The humans behind Squirrel

We are Merantix Momentum, a team of ~30 machine learning engineers, developing machine learning solutions for industry and research. Each project comes with its own challenges, data types and learnings, but one issue we always faced was scalable data loading, transforming and sharing. We were looking for a solution that would allow us to load the data in a fast and cost-efficient way, while keeping the flexibility to work with any possible dataset and integrate with any API. That's why we build Squirrel and we hope you'll find it as useful as we do! By the way, we are hiring!
