将 tensorflow 版本的预训练 bert model 转化为 pytorch 版本

0.安装python依赖

pip install -r requirement.txt

1.第一步

下载 tensorflow 版本的预训练 bert model : chinese_L-12_H-768_A-12

解压后放在当前目录下:

├── convert_tf_bert_model_to_pytorch
|  └── chinese_L-12_H-768_A-12
|  |  └── bert_config.json
|  |  └── bert_model.ckpt.data-00000-of-00001
|  |  └── bert_model.ckpt.index
|  |  └── ......

2.第二步

运行该代码:

python convert_tf_checkpoint_to_pytorch.py

转换成功的 pytorch 版本的预训练 model 会保存在:

├── convert_tf_bert_model_to_pytorch
|  └── chinese_L-12_H-768_A-12
|  |  └── pytorch_model.bin
|  |  └── ......

注意:

如果地址出现错误,请修改如下代码为自定义地址:

windows版本地址:

args.tf_checkpoint_path = "chinese_L-12_H-768_A-12\\bert_model.ckpt"
args.bert_config_file = "chinese_L-12_H-768_A-12\\bert_config.json"
args.pytorch_dump_path = "chinese_L-12_H-768_A-12\pytorch_model.bin"

linux版本地址:

args.tf_checkpoint_path = "./chinese_L-12_H-768_A-12/bert_model.ckpt"
args.bert_config_file = "./chinese_L-12_H-768_A-12/bert_config.json"
args.pytorch_dump_path = "./chinese_L-12_H-768_A-12/pytorch_model.bin"

也可以直接下载转换好的model:
