Missing dll cudnn_ops_infer64_8.dll does not generate a python error about onnxruntime

[yuslepukhin]

DLL loading especially indirect dependencies are handled by the OS. The message you are seeing is from a system loader.
Neither ORT nor Python have any control over that.

I understand from your response that neither ORT or python can change the error message that the OS generates when trying to load the dll. But I am not sure to understand why that would imply that ORT has no way to detect that the OS did not manage to load the library and then throw an error if that is the case. It seems to me that if the dll loading fail then we would get out_module == nullptr on this line https://github.com/microsoft/onnxruntime/blob/58d7b1220550f87ad58a195dc5605fa8c23fe98f/winml/lib/Api.Ort/OnnxruntimeEnvironment.cpp#L43C1-L45C4. and we should then be able to throw an error that gets propagated to python. I am missing something?
