[Web] I can’t use onnruntime-web to load a onnx model in a react web

[tanggang1997]

Describe the issue

When I use onnxruntime-web to load a onnx model in react web,I found error.

a)The error is:
Uncaught (in promise) Error: no available backend found. ERR: [wasm] Error: Aborted(CompileError: WebAssembly.instantiate(): expected magic word 00 61 73 6d, found 3c 21 44 4f @+0). Build with -sASSERTIONS for more info., [cpu] Error: previous call to 'initWasm()' failed., [xnnpack] Error: previous call to 'initWasm()' failed.

b)This is my code:
async function Load_Model() {
console.log(window.location.origin + "/node_modules/onnxruntime-web/dist/ort-wasm-simd.wasm");
env.wasm.wasmPaths = window.location.origin + "/node_modules/onnxruntime-web/dist/";
env.wasm.proxy = true;
// ort.env.wasm.wasmPaths = "https://cdn.jsdelivr.net/npm/onnxruntime-web@1.15.0/dist/";
const path = ${process.env.PUBLIC_URL}/model.onnx;
const session = await InferenceSession.create(path);
return session.inputNames[0]
};
Load_Model();
I don't know the detail about react.Does it need to config?

It is related to deploying WebAssembly files. Please refer to #19831 (comment).

BTW, before version 1.19.0-dev.20240521-068bb3d5ee, the version of WebAssembly file need to match the JS file.

关于部署 WebAssembly 文件有关。请参考#19831 (评论)。

顺便说一句，在 1.19.0-dev.20240521-068bb3d5ee 版本之前，WebAssembly 的版本需要与 JS 的版本相匹配。
First:
But i have setted :env.wasm.wasmPaths = window.location.origin + "/node_modules/onnxruntime-web/dist/";
I don't understand "The .wasm files are correctly deployed" ,can you tell me about the detail?
Second:
So I just upgarde the onnruntime-web version to 1.19.0-dev.20240521-068bb3d5ee?

env.wasm.wasmPaths = window.location.origin + "/node_modules/onnxruntime-web/dist/";

If you set this in the code, you also need to make sure the file is served by the server. I know that React has "dev" mode and "production" mode, and they may treat asset deployment differently. I am not an expert of React, so I cannot figure out the detail; but the whole idea is to make sure the URL of the .wasm file is actually valid ( which can be verified in your browser devtool, "Network" tab )

Thank you very much!!!
I have setted like this:ort.env.wasm.wasmPaths = "https://cdn.jsdelivr.net/npm/onnxruntime-web@1.15.0/dist/"; but it also gives me error.
Now, I want to ensure that wheather i need to upgarde the onnxruntime-web

You have 3 options:

• keep using env.wasm.wasmPaths = window.location.origin + "/node_modules/onnxruntime-web/dist/";, but you need to make sure the .wasm files are served correctly. For example, if your HTML is at http://localhost:8080/my/index.html, you need to make sure http://localhost:8080/my/node_modules/onnxruntime-web/dist/ort-wasm-simd.wasm can be accessed. This can be easily validated via browser. Usually the node_modules folder is excluded in dev server so you are unlikely to access that URL. A common way to deploy WASM is to copy the .wasm files into your public folder and set env.wasm.wasmPaths to there.
• you can use env.wasm.wasmPaths = "https://cdn.jsdelivr.net/npm/..." but as I mentioned above, please make sure the version is matched. If you are using version onnxruntime-web@1.17.0-dev.20240110-5f3113ecd6 you cannot use wasmPath pointing to version 1.15.0
• You can also upgrade to onnruntime-web version to 1.19.0-dev.20240521-068bb3d5ee; but you still to choose either serve the .wasm yourself or point path to CDN.
