tfjs-tflite: iOS Out of memory error with Cross-Origin Policy

[Jove125]

Hi,

According to this recomendations, it is necessary setting up cross-origin isolation: https://github.com/tensorflow/tfjs/tree/master/tfjs-backend-wasm#setting-up-cross-origin-isolation

Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp

After these settings, neural networks on a desktop PC and on android devices begin to work much faster. But the following error occurs on the iPhone (tested on iPhone 6S and 13 Max Pro). How can it be avoided?

Unhandled Promise Rejection: RangeError: Out of memory
promiseEmptyOnRejected — tflite_web_api_cc_threaded.js:287
promiseReactionJob

if to remove the server cross-origin settings, then everything works on the iPhone, but slowly.

html code to reproduce error:

<script src="./node_modules/@tensorflow/tfjs-core/dist/tf-core.min.js"></script>
<script src="./node_modules/@tensorflow/tfjs-backend-cpu/dist/tf-backend-cpu.min.js"></script>
<script src="./node_modules/@tensorflow/tfjs-tflite/dist/tf-tflite.min.js"></script>

<script>
var promise = tflite.loadTFLiteModel(modelPath, {numThreads: 4});
</script>
