===============================================

.. py:class:: lenskit.graphs.lightgcn.PairwiseLightGCNTrainer(scorer, data, options)
   

   Bases: :py:obj:`LightGCNTrainer`


   Protocol implemented by iterative trainers for models.  Models that
   implement :class:`UsesTrainer` will return an object implementing this
   protocol from their :meth:`~UsesTrainer.create_trainer` method.

   ..

       This protocol only defines the core aspects of training a model. Trainers
       should also implement :class:`~lenskit.state.ParameterContainer` to allow
       training to be checkpointed and resumed.

       It is also a good idea for the trainer to be pickleable, but the parameter
       container interface is the primary mechanism for checkpointing.
