How to use

How to use this model directly from the 🤗/transformers library:

from transformers import XLNetTokenizer, TFGPT2LMHeadModel
import jieba

# add spicel process 
class XLNetTokenizer(XLNetTokenizer):
    translator = str.maketrans(" \n", "\u2582\u2583")

    def _tokenize(self, text, *args, **kwargs):
        text = [x.translate(self.translator) for x in jieba.cut(text, cut_all=False)]
        text = " ".join(text)
        return super()._tokenize(text, *args, **kwargs)

    def _decode(self, *args, **kwargs):
        text = super()._decode(*args, **kwargs)
        text = text.replace(' ', '').replace('\u2582', ' ').replace('\u2583', '\n')
        return text


tokenizer = XLNetTokenizer.from_pretrained('mymusise/CPM-GPT2')
model = TFGPT2LMHeadModel.from_pretrained("mymusise/CPM-GPT2")

How to generate text

from transformers import TextGenerationPipeline


text_generater = TextGenerationPipeline(model, tokenizer)

texts = [
    '今天天气不错',
    '天下武功, 唯快不',
    """
