Announcing FiftyOne 0.23.3 and FiftyOne Teams 1.5.4

The Voxel51 engineering team is thrilled to announce the general availability of FiftyOneOne 0.23.3 and FiftyOne Teams 1.5.4, which bring with them dozens of enhancements and fixes to streamline your computer vision workflows.


In a nutshell, here’s what’s new:

This pair of releases include 30+ new features and fixes. Read on to learn more.

Wait, what’s FiftyOne?

FiftyOne is the open source machine learning toolset that enables data science teams to improve the performance of their computer vision models by helping them curate high quality datasets, evaluate models, find mistakes, visualize embeddings, and get to production faster.

Okay, but what’s FiftyOne Teams?

FiftyOne Teams extends FiftyOne with a GSuite-like experience for teams that want to collaborate on data stored in a centralized location with additional features like user permissions, dataset versioning, cloud-backed media, and enterprise security.

If this sounds interesting, read on! Then schedule a demo to learn more about FiftyOne Teams.

Get involved in the FiftyOne open source community!

If you are working on computer vision use cases and unstructured data, the FiftyOne community is for you. There are tons of ways to get involved, for example:

FiftyOne Community Slack

With over 2,000 members, the community Slack channel is a great place to interact with the FiftyOne developers and exchange solutions with machine learning engineers doing computer vision in production.

To make it easy to catch the highlights, every Friday we recap interesting questions and answers from Slack in our Tips & Tricks blog series. Check out almost 300 tips and tricks in the archives like:

Computer Vision and AI, Machine Learning, and Data Science Meetups

Voxel51 sponsors 13 virtual Computer Vision Meetups and 12 AI, Machine Learning and Data Science Meetups around the world with almost 18,000 members. (To join, visit the Meetup links and scroll down to find the location friendliest to your time zone.)

The Meetups are geared towards data scientists, machine learning engineers, and open source enthusiasts who want to expand their knowledge of computer vision and complementary technologies. We put an emphasis on open source software, and speakers who are computer vision practitioners or academics doing research in the field. Our next Meetup is happening this Thursday:

  • Lightning Talk: Next-Generation Image/Video editor Built with Generative AI – Mihail Eric at Storia AI
  • SANPO: A Scene Understanding, Accessibility, Navigation, Pathfinding, Obstacle Avoidance Dataset – Kimberly Wilber at Google Research
  • Setmlvis: Object Detection Comparison Using Set Visualization – Liudas Panavas at Northeastern University 
  • How well does the Segment Anything Model work on a Fisheye lens? – Nahid Alam at Cisco Meraki
