示例1: dict_from_params
# 需要导入模块: from allennlp.common import Params [as 别名]
# 或者: from allennlp.common.Params import items [as 别名]
def dict_from_params(cls, params: Params) -> 'Dict[str, TokenIndexer]': # type: ignore
"""
We typically use ``TokenIndexers`` in a dictionary, with each ``TokenIndexer`` getting a
name. The specification for this in a ``Params`` object is typically ``{"name" ->
{indexer_params}}``. This method reads that whole set of parameters and returns a
dictionary suitable for use in a ``TextField``.
Because default values for token indexers are typically handled in the calling class to
this and are based on checking for ``None``, if there were no parameters specifying any
token indexers in the given ``params``, we return ``None`` instead of an empty dictionary.
