wandb-core: A New Backend for the W&B SDK

Introduction

Good News, Everyone! We've developed a new and improved backend for the W&B SDK that is more performant, versatile, and robust.

Getting Started

To start using wandb-core, simply install the package in your environment. The wandb library will automatically detect and utilize it:

pip install -U wandb wandb-core

in the top of your script add the following:

import wandb

wandb.require("core")

Note: ensure you have wandb>0.16.6.

Platform Compatibility

wandb-core comes with wheels pre-built for the following platforms:

• Linux:x86_64, aarch64
• macOS: x86_64, arm64
• Windows amd64

For other platforms, build wandb-core from the source as outlined in our contributing guide. If you're interested in support for additional platforms, please inform us by opening a GitHub issue. Your feedback helps us prioritize new platform support.

W&B Server Compatibility

wandb-core is compatible with our production and dedicated cloud deployments as well as W&B Server versions >=0.40.0.

Switching Back to the Old SDK Backend

To revert to the old SDK backend, simply uninstall wandb-core from your environment:

pip uninstall wandb-core

or remove the wandb.require("core") from your script.
