What’s changed in TensorFlow.js 3.0
Release notes are available here. This release upgrades TypeScript to 4.8.4 and @webgpu/types to 0.1.21. If you don't use TypeScript, you can update to 4.0 without reading this doc.
Breaking Changes
This release is breaking for projects that use typescript<4.4. All other projects should be unaffected.
Upgrading Code from 3.x
For TypeScript >= 4.4
No breaking API changes were made in this release, so projects that use typescript>=4.4 can treat this as a minor release and upgrade
without any changes.
For TypeScript < 4.4
When using typescript<4.4, the following error will occur.
node_modules/@webgpu/types/dist/index.d.ts:587:16 - error TS2304: Cannot find name 'PredefinedColorSpace'.
587 colorSpace?: PredefinedColorSpace;
~~~~~~~~~~~~~~~~~~~~
...
To fix this, upgrade TypeScript to 4.4.2 or greater, or add the file predefined_color_space.d.ts (name and path can be changed) with the following contents to your project to define the missing type. Remove this file when TypeScript is upgraded to 4.4 or higher.
predefined_color_space.d.ts
type PredefinedColorSpace = "display-p3" | "srgb";
For TypeScript < 3.6
typescript<3.6 has the following additional error.
node_modules/@tensorflow/tfjs-core/dist/engine.d.ts:127:9 - error TS1086: An accessor cannot be declared in an ambient context.
127 get backend(): KernelBackend;
~~~~~~~
...
Enable skipLibCheck to suppress this error, or upgrade to at least TypeScript 3.6.2 to fix it (the above fix for PredefinedColorSpace will also need to be applied).
