Since pytorch 2.1 release we've made some BC breaking changes to the serialized schema. We should update it in time for the 2.2 release. Some of the changes include: * #114371 - custom class objects / pybinded objects are no longer saved directly to the `ExportedProgram` structure. Instead, the name is serialized inside of the program, and the actual bytes are stored. in a separate location from the exported program, allowing it to be saved to a different location. * #111204 - `GraphSignature` structure changed and `call_spec` is removed from the `GraphModule` schema * #111407 - `loss_outout` -> `loss_output` * #113075 - `example_inputs` removed from the `ExportedProgram` structure (this originally did not store anything), `dialect` added to the `ExportedProgram` structure. * #113689 - tensor constants are now lifted as inputs to the graph, and their locations are stored in the `GraphSignature` * #114172 - removed `equality_constraints` and added a `SymExprHint` for all symbolic expressions.
