[ExecuTorch][Weight Sharing] Track Named Data Store in EdgeProgramManager#9293
Conversation
…ager Pull Request resolved: #9151 We enable Backends to return Named Data by adding NamedDataStoreOutput to the preprocess result. This is a completely BC change, as no backends with an implemented preprocess will see any change if nothing is explicitly implemented. For backend developers to leverage the new NamedDataStore, they can initialize a new NamedDataStore() within preprocess, add_named_data to the data store, and return the NamedDataStore.get_named_data_store_output() in the preprocess result like such: ``` def preprocess(ExportedProgram, List[CompileSpecs]) -> PreprocessResult: named_data_store = NamedDataStore() for node in exported_program.graph.nodes: named_data_store.add_named_data("name", bytes) return PreprocessResult( processed_bytes=bytes, debug_handle_map={}, data_store_output= named_data_store.get_named_data_store_output() ) ``` Under the hood, the data store output is embedded in the loweredbackendmodule, (serializing loweredbackendmodule by itself with the a named_data_store_output is still a todo). But via the EdgeProgramManager path, we add the named_data_store_outputs to the edge_program_manger's named data store to keep track of all the named data returned by backends. ghstack-source-id: 271732049 @exported-using-ghexport Differential Revision: [D70451660](https://our.internmc.facebook.com/intern/diff/D70451660/)
