Chinese Pegasus
Model description
This model is pre-trained by UER-py, which is introduced in this paper.
You can download the set of Chinese PEGASUS models either from the UER-py Modelzoo page, or via HuggingFace from the links below:
Link | |
---|---|
PEGASUS-Base | L=12/H=768 (Base) |
PEGASUS-Large | L=16/H=1024 (Large) |
How to use
You can use this model directly with a pipeline for text2text generation (take the case of PEGASUS-Base):
>>> from transformers import BertTokenizer, PegasusForConditionalGeneration, Text2TextGenerationPipeline
>>> tokenizer = BertTokenizer.from_pretrained("uer/pegasus-base-chinese-cluecorpussmall")
>>> model = PegasusForConditionalGeneration.from_pretrained("uer/pegasus-base-chinese-cluecorpussmall")
>>> text2text_generator = Text2TextGenerationPipeline(model, tokenizer)
>>> text2text_generator("内容丰富、版式设计考究、图片华丽、印制精美。[MASK]纸箱内还放了充气袋用于保护。", max_length=50, do_sample=False)

Training data
CLUECorpusSmall is used as training data.
Training procedure
The model is pre-trained by UER-py on Tencent Cloud. We pre-train 1,000,000 steps with a sequence length of 512. Taking the case of PEGASUS-Base
python3 preprocess.py --corpus_path corpora/cluecorpussmall.txt \
--vocab_path models/google_zh_vocab.txt \
--dataset_path cluecorpussmall_pegasus_seq512_dataset.pt \
--processes_num 32 --seq_length 512 \
--data_processor gsg --sentence_selection_strategy random
python3 pretrain.py --dataset_path cluecorpussmall_pegasus_seq512_dataset.pt \
--vocab_path models/google_zh_vocab.txt \
--config_path models/pegasus/base_config.json \
--output_model_path models/cluecorpussmall_pegasus_base_seq512_model.bin \
--world_size 8 --gpu_ranks 0 1 2 3 4 5 6 7 \
--total_steps 1000000 --save_checkpoint_steps 100000 --report_steps 50000 \
--learning_rate 1e-4 --batch_size 8
Finally, we convert the pre-trained model into Huggingface's format:
python3 scripts/convert_pegasus_from_uer_to_huggingface.py --input_model_path cluecorpussmall_pegasus_base_seq512_model.bin-250000 \
--output_model_path pytorch_model.bin \
--layers_num 12
