tf in nodejs

[Ranaivoson Herimanitra]

Has someone managed to have  a working example using nodejs backend like express?

I've tone of issues using this :https://www.npmjs.com/package/@tensorflow/tfjs-node


One of examples errors I get after yarn start

node_modules/@tensorflow/tfjs-core/dist/engine.d.ts(65,24): error TS2304: Cannot find name 'ImageData'.
node_modules/@tensorflow/tfjs-core/dist/engine.d.ts(65,36): error TS2304: Cannot find name 'HTMLImageElement'.
node_modules/@tensorflow/tfjs-core/dist/engine.d.ts(65,55): error TS2304: Cannot find name 'HTMLCanvasElement'.
node_modules/@tensorflow/tfjs-core/dist/engine.d.ts(65,75): error TS2304: Cannot find name 'HTMLVideoElement'.


Herimanitra,

That might be an issue with your node install for your project.

Try looking at the MNIST demo for setup ideas: https://github.com/tensorflow/tfjs-node/tree/master/demo

I'd recommend deleting your node_modules folder and re-running yarn.

I replace my server with the link you provide.

I npm install everything

then yarn mnist

It gives me the attached error

Glad you figured it out. FYI, for the typescript error, if you are using tfjs-node within a typescript project, make sure you have "dom" as value in the "lib" property of your tsconfig.json (see this line). This adds typings for DOM elements which tfjs uses since it can also run in the browser.

Cheers!

Daniel
