By default, you can figure out what module an object belongs by checking __module__ and importing the result using __import__ or importlib.import_module. torch.package introduces module importers other than the default one. Each PackageImporter introduces a new namespace. Potentially a single name (e.g. 'foo.bar') is present in multiple namespaces. It supports two main operations: import_module: module_name -> module object get_name: object -> (parent module name, name of obj within module) The guarantee is that following round-trip will succeed or throw an ObjNotFoundError/ObjMisMatchError. module_name, obj_name = env.get_name(obj) module = env.import_module(module_name) obj2 = getattr(module, obj_name) assert obj1 is obj2 modules module_namereturncdS)zvImport `module_name` from this environment. The contract is the same as for importlib.import_module.

Args: obj: An object to get the module-environment-relative name for. name: If set, use this name instead of looking up __name__ or __qualname__ on `obj`. This is only here to match how Pickler handles __reduce__ functions that return a string, don't use otherwise. Returns: A tuple (parent_module_name, attr_name) that can be used to retrieve `obj` from this environment. Use it like: mod = importer.import_module(parent_module_name) obj = getattr(mod, attr_name) Raises: ObjNotFoundError: we couldn't retrieve `obj by name.

If you intern `a.b` but never use `a` in your code, then `a` will be an empty module with no source. This can break cases where we are trying to re-package an object after adding a real dependency on `a`, since OrderedImportere will resolve `a` to the dummy package and stop there.
