Angular & TensorFlow.js errors

TensorFlow General Discussion
1

Hi, it’s my first time using tensorflow.js with angular, I want to move my mouse on my hand movement, so I installed @tensorflow/tfjs and @tensorflow-models/handpose. I imported them in my module like so:

import * as tf from '@tensorflow/tfjs';
import * as handpose from '@tensorflow-models/handpose';

But it gives me errors, like 10x of this:

ERROR

2 export declare function hexToLong(hex: string): Long;
                                                  ~~~~

18     batch_input_shape?: Shape;

What can I do?

I am not really even sure how to use it in Angular, there’s not many resources on the internet, can someone provide me with documentation or useful info of how to use it and capture hand track please?

Thank you.

Hi!. Same issue, with angular 15.
In compilerOptions add:
“skipDefaultLibCheck”: true,
“skipLibCheck”: true,

Also just in case this is useful, Minko Gechev our DRE for Angular has been working with TensorFlow.js and gave a few talks etc showing how to integrate:
