ONNX Backend Env variable

[Heinrik-20]

Question

Hi,

For some context, I'm building an application that uses some of the models on huggingface as an annotation tool that helps create annotations for training a specialised model.

As for the specialised model, I am able to export them to onnx, and I was able to run this model in the same application, but I have to manually install the same onnxruntime-web version to be able to do so. I looked into the docs here, but I cannot access these functions through env.backends.onnx. I've tried console.log(env.backends.onnx.isONNXProxy()) and got

Uncaught (in promise) TypeError: env.backends.onnx.isONNXProxy is not a function

Is there a way I can access the same inference session through this package?

My package.json

    "dependencies": {
        "@huggingface/transformers": "3.7.5",
        "onnxruntime-web": "1.22.0-dev.20250409-89f8206ba4"
    },
