docs: Loads a YAML configuration from a string or file-like object.
  
      Parameters
      ----------
      stream : str or object
          Either a string containing valid YAML or a file-like object
          supporting the .read() interface.
      overrides : dict, optional
          A dictionary containing overrides to apply. The location of
          the override is specified in the key as a dot-delimited path
          to the desired parameter, e.g. "model.corruptor.corruption_level".
  
      Returns
      -------
      graph : dict or object
          The dictionary or object (if the top-level element specified an
          Python object to instantiate).
  
      Notes
      -----
      Other keyword arguments are passed on to `yaml.load`.
