      Creates a CL benchmark using the Tiny ImageNet dataset.
  
      If the dataset is not present in the computer, this method will
      automatically download and store it.
  
      The returned benchmark will return experiences containing all patterns of a
      subset of classes, which means that each class is only seen "once".
      This is one of the most common scenarios in the Continual Learning
      literature. Common names used in literature to describe this kind of
      scenario are "Class Incremental", "New Classes", etc. By default,
      an equal amount of classes will be assigned to each experience.
  
      This generator doesn't force a choice on the availability of task labels,
      a choice that is left to the user (see the `return_task_id` parameter for
      more info on task labels).
  
      The benchmark instance returned by this method will have two fields,
      `train_stream` and `test_stream`, which can be iterated to obtain
      training and test :class:`Experience`. Each Experience contains the
      `dataset` and the associated task label.
  
      The benchmark API is quite simple and is uniform across all benchmark
      generators. It is recommended to check the tutorial of the "benchmark" API,
      which contains usage examples ranging from "basic" to "advanced".
  
      :param n_experiences: The number of experiences in the current benchmark.
      :param return_task_id: if True, a progressive task id is returned for every
          experience. If False, all experiences will have a task ID of 0.
      :param seed: A valid int used to initialize the random number generator.
          Can be None.
      :param fixed_class_order: A list of class IDs used to define the class
          order. If None, value of ``seed`` will be used to define the class
          order. If non-None, ``seed`` parameter will be ignored.
          Defaults to None.
      :param shuffle: If true, the class order in the incremental experiences is
          randomly shuffled. Default to True.
      :param class_ids_from_zero_in_each_exp: If True, original class IDs
          will be mapped to range [0, n_classes_in_exp) for each experience.
          Defaults to False. Mutually exclusive with the
          ``class_ids_from_zero_from_first_exp`` parameter.
      :param train_transform: The transformation to apply to the training data,
          e.g. a random crop, a normalization or a concatenation of different
          transformations (see torchvision.transform documentation for a
          comprehensive list of possible transformations).
          If no transformation is passed, the default train transformation
          will be used.
      :param eval_transform: The transformation to apply to the test data,
          e.g. a random crop, a normalization or a concatenation of different
          transformations (see torchvision.transform documentation for a
          comprehensive list of possible transformations).
          If no transformation is passed, the default test transformation
          will be used.
      :param dataset_root: The root path of the dataset.
          Defaults to None, which means that the default location for
          'tinyimagenet' will be used.
  
      :returns: A properly initialized :class:`NCScenario` instance.
