roformer_pytorch's Introduction

PyTorch RoFormer

原版Tensorflow权重(https://github.com/ZhuiyiTechnology/roformer)

已经转化为PyTorch权重

手动权重转换

python convert_roformer_original_tf_checkpoint_to_pytorch.py \
    --tf_checkpoint_path=xxxxxx/chinese_roformer_L-12_H-768_A-12/bert_model.ckpt \
    --roformer_config_file=pretrained_models/chinese_roformer_base/config.json \
    --pytorch_dump_path=pretrained_models/chinese_roformer_base/pytorch_model.bin

tf与pytorch精度对齐

python compare.py
mean difference : tensor(4.3925e-07)
max  difference : tensor(7.6294e-06)

中文情感分类(chnsenti)

bash run_chnsenti.sh

结果

model chnsenti
tensorflow-NEZHA(base-wwm) 94.75
pytorch-NEZHA(base-wwm) 94.92
pytorch-RoFormer(base) 95.08
