SpacyTokenIndexer

@TokenIndexer.register("spacy")
class SpacyTokenIndexer(TokenIndexer):
 | def __init__(
 |     self,
 |     hidden_dim: int = 96,
 |     token_min_padding_length: int = 0
 | ) -> None

This SpacyTokenIndexer represents tokens as word vectors from a spacy model. You might want to do this for two main reasons; easier integration with a spacy pipeline and no out of vocabulary tokens.

Registered as a TokenIndexer with name "spacy".

Parameters

  • hidden_dim : int, optional (default = 96)
    The dimension of the vectors that spacy generates for representing words.
  • token_min_padding_length : int, optional (default = 0)
    See TokenIndexer.
