Onnx: What does "Operators with function registered" mean?

[kbullis]

Is there documentation on how these operators (DynamicQuantizeLinear, MeanVarianceNormalization, Range) differ from the "usual" operators, e.g. Conv?
Thanks

It means they are composite, built up from other operators. This is somewhat briefly discussed in https://github.com/onnx/onnx/blob/master/docs/AddNewOp.md, and I believe the original proposal is https://github.com/onnx/onnx/blob/master/docs/proposals/FunctionsProposal.md (although I don't think that proposal/motivation has fully materialized yet).

More clarification: ONNX targest to have a small set of primitive operators and flexible set of composed operators, which are using primitive ones to construct a graph representing their semantics.

Some more clarification about function were added https://github.com/onnx/onnx/blob/master/docs/IR.md#components.

Let me know whether this is clear enough or not please.

[kbullis]

Yes, that’s clear.

Thanks a lot.
