Solving Typescript-TensorflowJS incompat issues

If you're trying to use Tensorflow.js with Angular, which uses Typescript, you might run into an error that looks something like this.

node_modules/@types/webgl2/index.d.ts:582:13 - error TS2403: Subsequent variable declarations must have the same type.  Variable 'WebGL2RenderingContext' must be of type '{ new (): WebGL2RenderingContext; prototype: WebGL2RenderingContext; readonly ACTIVE_ATTRIBUTES: number; readonly ACTIVE_TEXTURE: number; readonly ACTIVE_UNIFORMS: number; readonly ALIASED_LINE_WIDTH_RANGE: number; ... 554 more ...; readonly WAIT_FAILED: number; }', but here has type '{ new (): WebGL2RenderingContext; prototype: WebGL2RenderingContext; readonly ACTIVE_ATTRIBUTES: number; readonly ACTIVE_TEXTURE: number; readonly ACTIVE_UNIFORMS: number; readonly ALIASED_LINE_WIDTH_RANGE: number; ... 555 more ...; readonly MAX_CLIENT_WAIT_TIMEOUT_WEBGL: number; }'.

582 declare var WebGL2RenderingContext: {
                ~~~~~~~~~~~~~~~~~~~~~~

  node_modules/typescript/lib/lib.dom.d.ts:16450:13
    16450 declare var WebGL2RenderingContext: {
                      ~~~~~~~~~~~~~~~~~~~~~~
Enter fullscreen mode Exit fullscreen mode

This is a compatibility issue between the existing version of WebGL2(0.0.4) and Typescript 3.6.

To solve this, just type

npm i --save @types/webgl2
Enter fullscreen mode Exit fullscreen mode

and rerun the application.

TF.js should now work without a glitch.

Cheers! Happy coding
