This is a Cairo implementation of a Decision transpiled from ONNX to Orion.
CairoVM failed to run the program (while it works with scarb cairo-run). I investigated and found that it was failing with the calc_ap_changes function of the cairo-lang-sierra-ap-change crate. In main.rs you can find a reproduction of the error. If you run cargo run you'll get the following error:
Error: ProgramRegistryError(FunctionIdAlreadyExists(FunctionId { id: 7525693132902674641, debug_name: Some("orion::operators::tensor::math::gather::gather[expr84]") }))%
