# 量化加速
|
||
量化是一种流行的模型压缩方法，量化后的模型拥有更小的体积和更快的推理速度.
|
||
FastDeploy基于PaddleSlim, 集成了一键模型量化的工具, 同时, FastDeploy支持部署量化后的模型, 帮助用户实现推理加速.
|
||
|
||
|
||
## FastDeploy 多个引擎和硬件支持量化模型部署
|
||
当前，FastDeploy中多个推理后端可以在不同硬件上支持量化模型的部署. 支持情况如下:
|
||
|
||
| 硬件/推理后端 | ONNX Runtime | Paddle Inference | TensorRT |
|
||
| :-----------| :-------- | :--------------- | :------- |
|
||
| CPU | 支持 | 支持 | |
|
||
| GPU | | | 支持 |
|
||
|
||
|
||
## 模型量化
|
||
|
||
### 量化方法
|
||
基于PaddleSlim, 目前FastDeploy提供的的量化方法有量化蒸馏训练和离线量化, 量化蒸馏训练通过模型训练来获得量化模型, 离线量化不需要模型训练即可完成模型的量化. FastDeploy 对两种方式产出的量化模型均能部署.
|
||
|
||
两种方法的主要对比如下表所示:
|
||
| 量化方法 | 量化过程耗时 | 量化模型精度 | 模型体积 | 推理速度 |
|
||
| :-----------| :--------| :-------| :------- | :------- |
|
||
| 离线量化 | 无需训练，耗时短 | 比量化蒸馏训练稍低 | 两者一致 | 两者一致 |
|
||
| 量化蒸馏训练 | 需要训练，耗时稍高 | 较未量化模型有少量损失 | 两者一致 |两者一致 |
|
||
|
||
### 用户使用FastDeploy一键模型量化工具来量化模型
|
||
Fastdeploy基于PaddleSlim, 为用户提供了一键模型量化的工具，请参考如下文档进行模型量化.
|
||
- [FastDeploy 一键模型量化](../../tools/auto_compression/)
|
||
当用户获得产出的量化模型之后，即可以使用FastDeploy来部署量化模型.
|
||
|
||
|
||
## 量化示例
|
||
目前, FastDeploy已支持的模型量化如下表所示:
