FutureWarning: torch.nn.utils.weight_norm is deprecated in favor of torch.nn.utils.parametrizations.weight_norm. #3074

    .. warning::

        This function is deprecated.  Use :func:`torch.nn.utils.parametrizations.weight_norm`
        which uses the modern parametrization API.  The new ``weight_norm`` is compatible
        with ``state_dict`` generated from old ``weight_norm``.

        Migration guide:

        * The magnitude (``weight_g``) and direction (``weight_v``) are now expressed
          as ``parametrizations.weight.original0`` and ``parametrizations.weight.original1``
          respectively.  If this is bothering you, please comment on
          https://github.com/pytorch/pytorch/issues/102999

        * To remove the weight normalization reparametrization, use
          :func:`torch.nn.utils.parametrize.remove_parametrizations`.

        * The weight is no longer recomputed once at module forward; instead, it will
          be recomputed on every access.  To restore the old behavior, use
          :func:`torch.nn.utils.parametrize.cached` before invoking the module
          in question.
