Usage

RedPost source code github Below is an example of how to use the FireRedChat-punc model for punctuation restoration:

git clone https://huggingface.co/hfl/chinese-lert-base FireRedChat-punc/chinese-lert-base

import os
from redpost import RedPost, RedPostConfig

punc_model_dir = "./FireRedChat-punc"
post_config = RedPostConfig(
    use_gpu=True,
    sentence_max_length=30
)
post_model = RedPost.from_pretrained(punc_model_dir, post_config)
batch_post_results = post_model.process([text], ["text"])
text = "".join([r["punc_text"] for r in batch_post_results])
text = re.sub("<unk>|<UNK>|\[unk\]|\[UNK\]", "", text)
print(text)
