TensorFlow.js 3.0

Breaking changes

This release contains a number of breaking changes, details of which are listed below, but at a high level these are some of the major changes in this release:

• We have removed the previously deprecated '*Strict' variants of ops. e.g. divStrict and mulStrict.
• If you are using tfjs-core directly (and not a higher level package like tfjs or tfjs-layers): gradients are no longer available without an explicit import, and the chaining api on tensors is now opt-in (requires an explicit import)

Notable additions:

• We now ship flat esm 'bundles'. E.g. https://cdn.jsdelivr.net/npm/@tensorflow/[email protected]/dist/tf.fesm.min.js, this gives you many of the benefits of ES modules but can be loaded in one request in a browser.

• We are introducing a workflow for shipping smaller bundles to browsers. Changes in TensorFlow.js 3.0 enable improved tree-shaking, and we are also introducing a CLI tool to create custom TensorFlow.js modules to feed into your bundling process. Read more about this feature here. 🔗
