tfds.deprecated.text.TokenTextEncoder

TextEncoder backed by a list of tokens.

Inherits From: TextEncoder

tfds.deprecated.text.TokenTextEncoder(
    vocab_list,
    oov_buckets=1,
    oov_token='UNK',
    lowercase=False,
    tokenizer=None,
    strip_vocab=True,
    decode_token_separator=' '
)

Tokenization splits on (and drops) non-alphanumeric characters with regex "\W+".

vocab_list list<str>, list of tokens.
oov_buckets int, the number of ints to reserve for OOV hash buckets. Tokens that are OOV will be hash-modded into a OOV bucket in encode.
oov_token str, the string to use for OOV ids in decode.
lowercase bool, whether to make all text and tokens lowercase.
tokenizer Tokenizer, responsible for converting incoming text into a list of tokens.
strip_vocab bool, whether to strip whitespace from the beginning and end of elements of vocab_list.
decode_token_separator str, the string used to separate tokens when decoding.

vocab_size Size of the vocabulary. Decode produces ints [1, vocab_size).
