Before Change

                pair["training_metadata"].store.store.filename)

After Change

            pair["training_metadata"].store = original_store.store.filename
    
        try:
            with open(filename, "wb") as out_file:
                pickle.dump(self, out_file)
        finally:
            // Restore the stores even if the pickling fails
            for original_store, pair in zip(original_stores, self.model):
                pair["training_metadata"].store = original_store
