Pass this to embedding_column or indicator_column to convert sequence
categorical data into dense representation for input to sequence NN, such as
RNN.
Number of the elements in the vocabulary. This must be no
greater than length of vocabulary_file, if less than length, later
values are ignored. If None, it is set to the length of vocabulary_file.
num_oov_buckets
Non-negative integer, the number of out-of-vocabulary
buckets. All out-of-vocabulary inputs will be assigned IDs in the range
[vocabulary_size, vocabulary_size+num_oov_buckets) based on a hash of
the input value. A positive num_oov_buckets can not be specified with
default_value.
default_value
The integer ID value to return for out-of-vocabulary feature
values, defaults to -1. This can not be specified with a positive
num_oov_buckets.
dtype
The type of features. Only string and integer types are supported.
Returns
A SequenceCategoricalColumn.
Raises
ValueError
vocabulary_file is missing or cannot be opened.
ValueError
vocabulary_size is missing or < 1.
ValueError
num_oov_buckets is a negative integer.
ValueError
num_oov_buckets and default_value are both specified.
