介绍

tf版本

https://github.com/ZhuiyiTechnology/WoBERT

pytorch版本

https://github.com/JunnYu/WoBERT_pytorch

安装(主要为了安装WoBertTokenizer)

pip install git+https://github.com/JunnYu/WoBERT_pytorch.git

使用

import torch
from transformers import BertForMaskedLM as WoBertForMaskedLM
from wobert import WoBertTokenizer

pretrained_model_or_path_list = [
    "junnyu/wobert_chinese_plus_base", "junnyu/wobert_chinese_base"
]
for path in pretrained_model_or_path_list:
    text = "今天[MASK]很好,我[MASK]去公园玩。"
    tokenizer = WoBertTokenizer.from_pretrained(path)
    model = WoBertForMaskedLM.from_pretrained(path)
    inputs = tokenizer(text, return_tensors="pt")
    with torch.no_grad():
        outputs = model(**inputs).logits[0]
    outputs_sentence = ""
    for i, id in enumerate(tokenizer.encode(text)):
        if id == tokenizer.mask_token_id:
            tokens = tokenizer.convert_ids_to_tokens(outputs[i].topk(k=5)[1])
            outputs_sentence += "[" + "||".join(tokens) + "]"
        else:
            outputs_sentence += "".join(
                tokenizer.convert_ids_to_tokens([id],
                                                skip_special_tokens=True))
    print(outputs_sentence)
