Fixing the Doctest

  Examples

  --------

  >>> import deepchem as dc

  >>> from pymatgen import Structure

  >>> import numpy as np

  >>> PRIMITIVE_CELL = {

  >>>   "lattice": [[2.818528, 0.0, 0.0],

  >>>               [-1.409264, 2.440917, 0.0],

  >>>             '-1', '-1', '-1', '-1', '0', '2']

  >>>                   }

  >>> }

  >>> featuriser = LCNNFeaturizer(**PRIMITIVE_CELL_INF0)

  >>> featuriser = dc.feat.LCNNFeaturizer(**PRIMITIVE_CELL_INF0)

  >>> print(type(featuriser._featurize(Structure(**DATA_POINT))))
