cogdata.utils.cogview.sp\_tokenizer module
------------------------------------------

SentencePiece tokenizer. from https://github.com/openai/gpt-2/, changed for chinese

SentencePiece is an unsupervised text tokenizer and detokenizer mainly for Neural Network-based text generation 
systems where the vocabulary size is predetermined prior to the neural model training. SentencePiece implements 
subword units (e.g., byte-pair-encoding (BPE) [Sennrich et al.]) and unigram language model [Kudo.]) with the 
extension of direct training from raw sentences. SentencePiece allows us to make a purely end-to-end 
system that does not depend on language-specific pre/postprocessing.
