2.循环推理，GPT-2模型不像其他模型一样只需要执行一次推理，而是需要循环执行多次推理才能完成。首先，模型推理限定在for循环中，将输入数据input_ids，输入到model.run({...})中执行推理，生成一个token的id。其次，将推理结果拼接到输入数据input_ids中，执行下一次循环。最后，当循环结束或者生成的词为[SEP]结束标志符时，完成GPT-2模型的整体推理。如下图所示，为GPT-2模型的一次完整推理过程。 2.循环推理，GPT-2模型不像其他模型一样只需要执行一次推理，而是需要循环执行多次推理才能完成。首先，模型推理限定在for循环中，将输入数据input_ids，输入到model.run({...})中执行推理，生成一个token的id。其次，将推理结果拼接到输入数据input_ids中，执行下一次循环。最后，当循环结束或者生成的词为[SEP]结束标志符时，完成GPT-2模型的整体推理。如下图所示，为GPT-2模型的一次完整推理过程。

GPT2主要使用Transformer的Decoder模块为特征提取器，并对Transformer Decoder进行了一些改动，原本的Decoder包含了两个Multi-Head Attention结构，而GPT2只保留了Mask Multi-Head Attention。 GPT2主要使用Transformer的Decoder模块为特征提取器，并对Transformer Decoder进行了一些改动，原本的Decoder包含了两个Multi-Head Attention结构，而GPT2只保留了Mask Multi-Head Attention。
## 构建安装 ## Python版本推理
在光源可拉取推理的docker镜像，GPT2模型推理的镜像如下： 本次采用GPT-2模型进行诗词生成任务，模型文件下载链接：https://pan.baidu.com/s/1KWeoUuakCZ5dualK69qCcw , 提取码：4pmh ，并将GPT2_shici.onnx模型文件保存在Resource/文件夹下。下面介绍如何运行python代码示例，Python示例的详细说明见Doc目录下的Tutorial_Python.md。
### 下载镜像
在光源中下载MIGraphX镜像：
```python ```python
docker pull image.sourcefind.cn:5000/dcu/admin/base/custom:ort1.14.0_migraphx3.0.0-dtk22.10.1 docker pull image.sourcefind.cn:5000/dcu/admin/base/custom:ort1.14.0_migraphx3.0.0-dtk22.10.1
``` ```
### 安装Opencv依赖 ### 设置Python环境变量
```
export PYTHONPATH=/opt/dtk/lib:$PYTHONPATH
```
### 安装依赖
```python ```python
cd <path_to_migraphx_samples> # 进入gpt2 migraphx工程根目录
sh ./3rdParty/InstallOpenCVDependences.sh cd <path_to_gpt2_migraphx>
# 进入示例程序目录
cd ./Python/
# 安装依赖
pip install -r requirements.txt
``` ```
### 修改CMakeLists.txt ### 设置动态shape模式
```python
export MIGRAPHX_DYNAMIC_SHAPE=1
```
### 运行示例
在Python目录下执行如下命令运行该示例程序：
```python
python gpt2.py
```
如下所示，采用交互式界面，通过输入开头诗词，GPT2模型可以生成后续的诗句。

- 如果使用ubuntu系统，需要修改CMakeLists.txt中依赖库路径： ### 修改CMakeLists.txt
将"${CMAKE_CURRENT_SOURCE_DIR}/depend/lib64/"修改为"${CMAKE_CURRENT_SOURCE_DIR}/depend/lib/"
- **MIGraphX2.3.0及以上版本需要c++17** 如果使用ubuntu系统，需要修改CMakeLists.txt中依赖库路径：

### python版本推理
1.参考《MIGraphX教程》中的安装方法安装MIGraphX并设置好PYTHONPATH
2.安装依赖：
```python
# 进入migraphx samples工程根目录
cd <path_to_migraphx_samples>
# 进入示例程序目录
cd Python/NLP/GPT2
# 安装依赖
pip install -r requirements.txt
``` ```
3.设置环境变量：
```python
# 设置动态shape模式
export MIGRAPHX_DYNAMIC_SHAPE=1 export MIGRAPHX_DYNAMIC_SHAPE=1
``` ```
4.在Python/NLP/GPT2目录下执行如下命令运行该示例程序： ### 运行示例
```python ```python
python gpt2.py # 进入gpt2 migraphx工程根目录
``` cd <path_to_gpt2_migraphx>
如下所示，采用交互式界面，通过输入开头诗词，GPT2模型可以生成后续的诗句。
<img src="./Doc/Images/GPT_03.png" style="zoom:80%;" align=middle>
### C++版本推理
切换到build目录中，执行如下命令：
```python # 进入build目录
cd ./build/ cd ./build/
./MIGraphX_Samples
```
根据提示选择运行GPT2模型的示例程序 # 执行示例程序
./GPT2
```python
# 设置动态shape模式
export MIGRAPHX_DYNAMIC_SHAPE=1
# 运行示例
./MIGraphX_Samples 0
``` ```
如下所示，采用交互式界面，通过输入开头诗词，GPT2模型可以推理出后续的诗句。 如下所示，采用交互式界面，通过输入开头诗词，GPT2模型可以推理出后续的诗句。
