      """Load Delaney dataset
  
      The Delaney (ESOL) dataset a regression dataset containing structures and
      water solubility data for 1128 compounds. The dataset is widely used to
      validate machine learning models on estimating solubility directly from
      molecular structures (as encoded in SMILES strings).
  
      Scaffold splitting is recommended for this dataset.
  
      The raw data csv file contains columns below:
  
      - "Compound ID" - Name of the compound
      - "smiles" - SMILES representation of the molecular structure
      - "measured log solubility in mols per litre" - Log-scale water solubility
          of the compound, used as label
  
      Parameters
      ----------
      featurizer: Featurizer or str
          the featurizer to use for processing the data.  Alternatively you can pass
          one of the names from dc.molnet.featurizers as a shortcut.
      splitter: Splitter or str
          the splitter to use for splitting the data into training, validation, and
          test sets.  Alternatively you can pass one of the names from
          dc.molnet.splitters as a shortcut.  If this is None, all the data
          will be included in a single dataset.
      transformers: list of TransformerGenerators or strings
          the Transformers to apply to the data.  Each one is specified by a
          TransformerGenerator or, as a shortcut, one of the names from
          dc.molnet.transformers.
      reload: bool
          if True, the first call for a particular featurizer and splitter will cache
          the datasets to disk, and subsequent calls will reload the cached datasets.
      data_dir: str
          a directory to save the raw data in
      save_dir: str
          a directory to save the dataset in
