T3Weights.from_t3svd
====================

      def from_t3svd(cls, x: 'TuckerTensorTrain', **kwargs) -> 'T3Weights':


   The singular values of ``x`` as a weight object -- the canonical (unmodified) σ's, so
   ``from_t3svd(x).reciprocal()`` is the inverse-σ (Grasedyck-Kramer) weighting. ``**kwargs`` pass to
   :py:meth:`t3svd`; the weights are shape-consistent with the ``t3svd`` result (with ``x`` itself when
   ``x`` has minimal ranks, the usual case).
