pad_and_truncate(sequence: List[float], max_len: int, dtype: str = 'int64', padding: str = 'post', truncating: str = 'post', value: int = 0) → numpy.ndarray[source]

Helper method for padding and truncating text and aspect segment.

Parameters

  • sequence (List[float]) – input sequence of indices

  • max_len (int) – maximum len to pad

  • dtype (str, optional) – data type to cast indices. Defaults to “int64”.

  • padding (str, optional) – type of padding, ‘pre’ or ‘post’. Defaults to “post”.

  • truncating (str, optional) – type of truncating, ‘pre’ or ‘post’. Defaults to “post”.

  • value (int, optional) – value used for padding. Defaults to 0.

Returns

return a ndarray padded to the max_len

Return type

np.ndarray
