I wrote the below code

    @functools.wraps(fxn)
    def set_loader_wrapper(self, *args, **kwargs):
        warnings.warn('The    import    system    now    takes    care    of    this    automatically.', DeprecationWarning, stacklevel=2)
        module = fxn(self, *args, **kwargs)
        if (getattr(module, '__loader__', None) is None):
            module.__loader__ = self
        return module
    return set_loader_wrapper
