+**注意：** 量化训练需要依赖Paddle develop分支，可在[PaddlePaddle每日版本](https://www.paddlepaddle.org.cn/documentation/docs/zh/install/Tables.html#whl-dev)中下载安装合适的PaddlePaddle版本。
+
+#### 安装PaddleSlim
+- 方法一：直接安装：
+```
+pip install paddleslim -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+- 方法二：编译安装：
+```
+git clone https://github.com/PaddlePaddle/PaddleSlim.git
+cd PaddleSlim
+python setup.py install
+```
 
 ## 快速开始
