I am creating a body segmentation app using tensorflow bodypix model. It works fine in the browser. I am using webpack to use its modules(see below)
import * as wasm from "@tensorflow/tfjs-backend-wasm";
import * as tf from "@tensorflow/tfjs-core";
import * as bodyPix from "@tensorflow-models/body-pix";
wasm.setWasmPaths("./wasm/");
tf.setBackend("wasm").then(() => {
//some simple vanilla js code
});
//some more vanilla js code...
It works exactly fine in chrome and giving output as expected after running npx webpack .
However when irun it with electron simply by creating a main electron file it outputs nothing but a blank white screen with the following error in console-
Uncaught TypeError: this.util.TextEncoder is not a constructor
at new <anonymous> (main.js:2)
the line where it is pointing is from a minified codew which looks like this-
...SOME_CODE...&&Me().setPlatform("node",new class{
constructor(){this.util=n(758),this.textEncoder=new this.util.TextEncoder}...SOME_MORE_CODE...
i thought that electron is simply chrome without top bars, but this seems wrong. can someone help me here i am using following versions-
"nodejs v12.16.3", "electron11.1.1", "tfjs2.8.2"
see the screen shot of chrome and electron-

i previously had
wasm.setWasmPaths("./wasm/");
tf.setBackend("wasm").then(() => {
//some simple vanilla js code
});
in my main code, and i have copied the folder from wasm(dist/) to project's folder.
Deleting the same from my project's folder and changing the code to -
wasm.setWasmPaths("../node_modules/@tensorflow/tfjs-backend-wasm/dist/"); //or start from ./ if your main file is in same folder as node_modules
tf.setBackend("wasm").then(() => {
//...
});
Error loading TensorflowJS in Electron App (Nodejs)
i got the solution by creating an electron hello world project and then adding tfjs, then tfjs-backend-wasm. the new project is working correctly but however even moving the node_modules from new project to older one is not working for the older. but as soon i changed the wasm path, it worked giving no error.
now I have encountered the problem several times and everytime it's solved by creating a new folder, first installing electron and creating a simple electron app first, and then installing other dependencies and copying old code in the new folder.(warning: don't copy the node modules folder)
It seems to be a bug in tfjs or electron
