Describe the problem or feature request
When I run a simple example with tfjs and tjfs-node in my terminal, I get warnings about tfjs failing to register the webgl backend. But I don’t care about that, I only want the node/cpu backend. Is there a way to make tfjs not attempt to register the webgl backend, or, to not throw those warnings/errors?
Code to reproduce the bug / link to feature request
import * as tf from '@tensorflow/tfjs';
// Node CPU backend
import '@tensorflow/tfjs-node';
...
const sample: tf.Tensor1D = tf.tensor1d(new Array(5));
...
Errors:
console.warn node_modules/@tensorflow/tfjs-core/dist/environment.js:186
Registration of backend webgl failed
console.warn node_modules/@tensorflow/tfjs-core/dist/environment.js:187
Error: WebGL is not supported on this device

So it turns out this problem is due to
jest, or the interaction betweenjestandtfjs. The problem isjest, by default, seems to mock a browser-like environment, whichtfjsdetects and thus tries to load browser stuff like the webgl backend. Adding"testEnvironment": "node"to thejestconfig in mypackage.jsonresolved these issues. It’s a bit annoying that the default behavior was like this with no obvious clues as to what was going on, but I can’t say this is an issue withtfjs. Maybe there should be a comment in some readme somewhere about this 😃 Anyway, thanks again for looking into this, it’s appreciated!I got the same issue and for that, I had to add these lines in packages.json:
and this import in jest setup file
