class_docstr: The external storage class implemented by smart_open.
  (https://github.com/RaRe-Technologies/smart_open)
  
  Smart open supports multiple backend with the same APIs.
  
  To use this implementation, you should pre-create the given uri.
  For example, if your uri is a local file path, you should pre-create
  the directory.
  
  Args:
      uri: Storage URI used for smart open.
      prefix: Prefix of objects that are stored.
      override_transport_params: Overriding the default value of
          transport_params for smart-open library.
  
  Raises:
      ModuleNotFoundError: If it fails to setup.
          For example, if smart open library
          is not downloaded, this will fail.
