class_docstr: Calculate atomic coordinates.
  
  Examples
  --------
  >>> import deepchem as dc
  >>> from rdkit import Chem
  >>> mol = Chem.MolFromSmiles('C1C=CC=CC=1')
  >>> n_atoms = len(mol.GetAtoms())
  >>> n_atoms
  6
  >>> featurizer = dc.feat.AtomicCoordinates(use_bohr=False)
  >>> features = featurizer.featurize([mol])
  >>> type(features[0])
  <class 'numpy.ndarray'>
  >>> features[0].shape # (n_atoms, 3)
  (6, 3)
  
  
  Note
  ----
  This class requires RDKit to be installed.
docstr: Parameters
  ----------
  use_bohr: bool, optional (default False)
      Whether to use bohr or angstrom as a coordinate unit.
