Print a log message. Args: msg (str): The message to be logged. logger (logging.Logger | str | None): The logger to be used.

Get the registry record. Args: key (str): The class name in string format. Returns: class: The corresponding c

Returns list of utf-8 byte and a corresponding list of unicode strings. The reversible bpe codes work on unicode strings. This means you

Initialize and get a logger by name. If the logger has not been initialized, this method will initialize the logger by adding one or two handl

Return set of symbol pairs in a word. Word is represented as tuple of symbols (symbols being variable-length strings).
