missing sampler

[jasonzhang761213]

thanks for the great job.

inference has no problem，it runs well.
but the original project contains sampler,
the onnx models contains no sampler onnx model.
can this be resolved?

Thank you for stopping by! I'm glad to hear that everything is working well for you.

About sampler, I intentionally excluded it during the ONNX export process. My primary goal for this repository was to optimize the original model for edge devices, where including the diffusion sampler would increase inference speed and VRAM consumption. Beside, implementing diffusion logic in C++ is quite complex, and some layers within the sampler may not yet be fully supported by ONNX or C++ runtimes.

However, I will provide the export code to ONNX in a new branch so you can experiment with it yourself. I hope this helps!
