Before trying WASM, i was running my model in browser [script] with CPU back-end [Without WebGL] and it was working fine but obviously it was slow.

Then I am trying to change the back-end to the WASM I made the following change, inside the index.html file, i added,

<script src="https://unpkg.com/@tensorflow/tfjs"></script>
 <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-backend-wasm/dist/tf-backend-wasm.js"></script>
    <script>
     tf.setBackend('wasm').then(() => init());
    </script>

When i am running the index.html, in the browser console i am getting the following error -->

backend.ts:662 Uncaught (in promise) Error: 'zerosLike' not yet implemented or not found in the registry. Did you forget to import the kernel?

Background of my model: I am using custom trained cocoSSD-mobilenet. index.js

const LOCAL_MODEL_PATH = 'http://../model.json';
model = await tf.loadGraphModel(LOCAL_MODEL_PATH);
....
output = await model.executeAsync(image);

please Help:-) Thanks.

@syonfox another issue would be great, we can implement it.

Right now I am just learning tensorflowjs and webassembaly, I was just wanted to Post a bug that oneHot is also not implemented in wasm. I could look into adding it but it would take a while to learn the project structure. Should I perhaps create a new issue since this is already closed? The reason I put it here was the issue looks like the same problem.
