Model rename and Model load issue

[technic404]

When firstly executed node index.mjs with the sample code for node.js, provided error occurs:

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[Error: ENOENT: no such file or directory, rename 'F:\Programming\.cache\aislamov\stable-diffusion-2-1-base-onnx\model_index.json.tmp' -> ''F:\Programming\.cache\aislamov\stable-diffusion-2-1-base-onnx\model_index.json'] {                                                -> 
  errno: -4058,
  code: 'ENOENT',
  syscall: 'rename',
  path: ''F:\Programming\\.cache\\aislamov\\stable-diffusion-2-1-base-onnx\\model_index.json.tmp',
  dest: ''F:\Programming\\.cache\\aislamov\\stable-diffusion-2-1-base-onnx\\model_index.json'
}

When I run that secondly, another error occurs:

Downloading model_index.json | ████████████████████████████████████████ | 100% | 587 Bytes/587 Bytes
undefined:1


SyntaxError: Unexpected end of JSON input

Node.js v18.15.0

I think here is similar error to that first one - model_index.json.tmp should be renamed to model_index.json, so then the Unexpected end of JSON input won't occur anymore.

Last error i got is:

F:\Programming\node_modules\onnxruntime-node\dist\backend.js:24
            __classPrivateFieldGet(this, _OnnxruntimeSessionHandler_inferenceSession, "f").loadModel(pathOrBuffer, options);
                                                                                           ^

Thanks for the feedback, i will fix the rename issue in the next release. As you use node.js with CPU, you need to add --rev cpu to command line when running node example. That way it will download a special model version without GPU-specific optimizations

CUDA/DML providers for node.js are not yet released by ONNX team (my PR for that was already merged microsoft/onnxruntime#16050 )
