Current Behaviour?

Hello, I'm a developer of Tensorflow.NET, which is a tensorflow binding for dotnet. When I implemented some feature, I could not find a C API to add attributes to an operation that has already been created and added to the graph. However, there is indeed such C API for python. It's located here.

Among exported C APIs of libtensorflow, only the following API was found:

TF_CAPI_EXPORT extern void TF_SetAttrValueProto(TF_OperationDescription* desc,
                                                const char* attr_name,
                                                const void* proto,
                                                size_t proto_len,
                                                TF_Status* status);

However, TF_OperationDescription is released after adding the operation to graph by calling TF_FinishOperation. Therefore I can't use the API to add attributes.

Is there any other way for us to add attributes for operations which have been added to graph?

Standalone code to reproduce the issue

The code is wrote in csharp. I'll give a minimal example if needed.

Also, is there any corresponding C API for GetHandleShapeAndType and SetHandleShapeAndType in python_api.h?
