We would love to see onnx support in the pipelines, it would make serving models much more scalable.
Actually we have never worked with onnx, but the statistics look pretty good.
What do you think about automatically generating onnx models next to TF and pytorch models, so over the time any uploaded model on HF hub would be available as onnx model too.
We would love to help you there, but need to read more into onnx runtime.
