  lowercase__			=	'''
  Distills an NLI-based zero-shot classifier to a smaller, more efficient model with a fixed set of candidate class
  names. Useful for speeding up zero-shot classification in cases where labeled training data is not available, but
  when only a single fixed set of classes is needed. Takes a teacher NLI model, student classifier model, unlabeled
  dataset, and set of K possible class names. Yields a single classifier with K outputs corresponding to the provided
  class names.
