.. py:class:: DatasetFactory(dataset_wrapper_factory = None)

   Bases: :py:obj:`ksuit.factory.base.Factory`


   Base factory. Implements base structures for creating a single object, a list of objects and a dict
   of objects. The main difference between these methods are the default return values. As python does not like using
   an empty list/dict as default value for an argument, arguments are by default often None. By differentiating
   between these three types, one avoids none checks whenever the factory is called.
   - create: creates an object.
   - create_list: creates a list of objects.
   - create_dict: creates a dict of objects.

   For example, creating a list
   ```
   class Example:
       def __init__(self, callbacks: list[Callback] | None = None)
           # automatic none check in create_list (this is how FactoryBase is implemented)
           self.callbacks = create_list(callbacks)
           # required none check after creating the list (this is how one could implement it without create_list)
           self.callbacks = create(callbacks) or []
   ```


   .. py:attribute:: dataset_wrapper_factory


   .. py:method:: instantiate(object_config = None, **_)

      Instantiates the dataset either based on `dataset_config` or from the checkpoint.
