# [Q8BERT Description](#contents)
|
||||||
|
|
||||||
|
[Q8BERT](https://arxiv.org/abs/1910.06188) is a quantization-aware training during the fine-tuning phase of [BERT](https://arxiv.org/abs/1810.04805)
|
||||||
|
in order to compress BERT by 4× with minimal accuracy loss. Furthermore, the
|
||||||
|
produced quantized model can accelerate inference speed if it is optimized for 8bit Integer supporting hardware.

||||||

|
# [Model Architecture](#contents)
|
||||||
|
|
||||||
|
The backbone structure of Q8BERT is transformer, the transformer contains 12 encoder modules, one encoder contains one self-attention module and one self-attention module contains one attention module.

# [Quick Start](#contents)
|
||||||
|
|
||||||
|
After installing MindSpore via the official website, you can start training and evaluation as follows:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
|
||||||
|
# run training example
|
||||||
|
run_train.sh
|
||||||
|
|
||||||
|
Before running the shell script, please set the `task_name`, `teacher_model_dir`, `student_model_dir` and `data_dir` in the run_train.sh file first.
|
||||||
|
|
||||||
|

|
||||||
|
Before running the command below, please check `data_dir` and 'load_ckpt_path' has been set. Please set the path to be the absolute full path, e.g:"/home/xxx/model_dir/".
|
||||||
|
|
||||||
|
```text
|
||||||

python
|
||||||
|
python ./run_train.py --device_target="GPU" --do_eval="true" --epoch_num=3 --task_name="STS-B" --do_shuffle="true" --enable_data_sink="true" --data_sink_steps=100 --save_ckpt_step=100 --max_ckpt_num=1 --load_ckpt_path="sts-b.ckpt" --train_data_dir="sts-b/train.tf_record" --eval_data_dir="sts-b/eval.tf_record" --device_id=0 --logging_step=100 --do_quant="true"

shell
|
||||||
|
sh run_train.sh
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
The shell command above will run in the background, you can view the results the file log.txt. The python command will run in the console, you can view the results on the interface. After training, you will get some checkpoint files under the script folder by default. The eval metric value will be achieved as follows:

# Q8BERT概述
|
||||||
|
|
||||||
|
[Q8BERT](https://arxiv.org/abs/1910.06188)是一种在finetune阶段使用量化训练BERT后的模型,最后是训练出来的模型在保证精度损失的情况下,模型大小压缩４倍,而且使用这种算法训练出来的模型在含有8bit算子的硬件上,推理速度也可以相应提高

||||||
|
|
||||||
|
# 数据集
|
||||||
|
|
||||||
|
- 下载GLUE数据集进行任务蒸馏。将数据集由JSON格式转化为TFRecord格式。详见[BERT](https://github.com/google-research/bert)代码库中的run_classifier.py文件。
|
||||||
|
|
||||||
|
# 环境要求
|
||||||
|
|
||||||
|

# 快速入门
|
||||||
|
|
||||||
|
从官网下载安装MindSpore之后，可以开始使用如下脚本训练和推理：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 运行训练脚本
|
||||||
|
run_train.sh
|
||||||
|
|
||||||
|
Before running the shell script, please set the `task_name`, `teacher_model_dir`, `student_model_dir` and `data_dir` in the run_train.sh file first.
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
若在Ascend设备上运行分布式训练，请提前创建JSON格式的HCCL配置文件。
|
||||||
|
详情参见如下链接：
|
||||||
|
https:gitee.com/mindspore/mindspore/tree/master/model_zoo/utils/hccl_tools.
|
||||||
|
|
||||||
|
如需设置数据集格式和参数，请创建JSON格式的视图配置文件，详见[TFRecord](https://www.mindspore.cn/doc/programming_guide/zh-CN/master/dataset_loading.html#tfrecord) 格式。
|
||||||
|
|
||||||
|
```text
|
||||||
|
For general task, schema file contains ["input_ids", "input_mask", "segment_ids"].
|
||||||
|
|
||||||
|
For task distill and eval phase, schema file contains ["input_ids", "input_mask", "segment_ids", "label_ids"].
|
||||||
|
|
||||||
|
`numRows` is the only option which could be set by user, the others value must be set according to the dataset.

## 训练流程
|
||||||
|
|
||||||
|
### 用法
|
||||||
|
|
||||||
|
#### Ascend处理器上运行
|
||||||
|
|
||||||
|
运行以下命令前，确保已设置'data_dir'和'load_ckpt_path'。请将路径设置为绝对全路径，例如/username/checkpoint_100_300.ckpt。
|
||||||
|
|
||||||
|
```text
|
||||||
|
|
||||||
|
python
|
||||||
|
python ./run_train.py --device_target="GPU" --do_eval="true" --epoch_num=3 --task_name="STS-B" --do_shuffle="true" --enable_data_sink="true" --data_sink_steps=100 --save_ckpt_step=100 --max_ckpt_num=1 --load_ckpt_path="sts-b.ckpt" --train_data_dir="sts-b/train.tf_record" --eval_data_dir="sts-b/eval.tf_record" --device_id=0 --logging_step=100 --do_quant="true"
|
||||||
|
shell
|
||||||
|
sh run_train.sh
|
||||||
|
|
||||||
|
以上命令后台运行，您可以在log.txt文件中查看运行结果。训练结束后，您可以在默认脚本文件夹中找到检查点文件。得到如下损失值：
|
||||||
|
epoch: 1, step: 100, loss are (Tensor(shape=[], dtype=Float32, value= 0.526506), Tensor(shape=[], dtype=Bool, value= False)) The current result is {'pearson': 0.8407084843799768, 'spearmanr': 0.8405771469597393, 'corr': 0.840642815669858} epoch time: 66421.602 ms, per step time: 664.216 ms
|
||||||
|
epoch: 2, step: 200, loss are (Tensor(shape=[], dtype=Float32, value= 0.406012), Tensor(shape=[], dtype=Bool, value= False)) The current result is {'pearson': 0.826509808575773, 'spearmanr': 0.8274141859302444, 'corr': 0.8269619972530087} epoch time: 47488.633 ms, per step time: 474.886 ms
