### Description <!-- Describe your changes. --> Changes to support standalone custom ops in a minimal build. Also incorporates changes from #14492 (needed to test builds prior to that being checked in). We first need to save the schema info from the operators used by the standalone op invoker in the ORT format model. Add mechanism for that. Merge the kernel lookup logic so the same is used in full and minimal build. NOTE: the version matching is now consistent with all other kernel lookups, and the call to CreateOp MUST use the exact version for the operator. Previously matching wasn't as strict, but this can lead to the incorrect kernel being chosen. Add tests. NOTE: There is currently no way to detect the ops/types/opsets used inside these custom ops as they don't exist until we create kernels, which is after model loading completes (which is the point the ORT format model is saved). Due to that they have to be manually added to the configuration used to do the reduced ops build. That shouldn't be too hard for the custom op author to add given the custom op implementation is specifying the op, opset and type constraints (i.e. they have the info and it's just a case of capturing/formatting it correctly). ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> Enable usage of the standalone op invoker by custom ops in a minimal build. --------- Co-authored-by: Edward Chen <18449977+edgchen1@users.noreply.github.com> |
