List Avaible ONNX operators for custom libraries

[JorgeMIng]

I have been using the function "onnxruntime.capi.onnxruntime_pybind11_state.get_all_operator_schema()" to retrieve all the OpSchemas of the operators. I believe the function does not extend to custom operators introduced with "register_custom_ops_library()". I have been examining the library and the code to find any information or method to get this information. Does anyone know where new operators are stored or how to access their metadata?

The information does not need to be directly a OpSchema at least the functions and then I can try to parse the information from there.
