+
+## 1. 简介
+飞桨模型转换工具[X2Paddle](https://github.com/PaddlePaddle/X2Paddle)支持将```Caffe/TensorFlow/ONNX/PyTorch```的模型一键转为飞桨（PaddlePaddle）的预测模型。借助X2Paddle的能力，PaddleSlim的自动压缩功能可方便地用于各种框架的推理模型。
+
+本示例将以[TensorFlow](https://github.com/tensorflow/tensorflow)框架的MobileNetV1模型为例，介绍如何自动压缩其他框架中的图像分类模型。本示例会利用[TensorFlow](https://github.com/tensorflow/models)开源models库，将TensorFlow框架模型转换为Paddle框架模型，再使用ACT自动压缩功能进行自动压缩。本示例使用的自动压缩策略为量化训练。
+

+
+## 3. 自动压缩流程
+
+#### 3.1 准备环境
+- PaddlePaddle >= 2.3 （可从[Paddle官网](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/pip/linux-pip.html)下载安装）
+- PaddleSlim develop版本
+- [X2Paddle](https://github.com/PaddlePaddle/X2Paddle) >= 1.3.6
+- opencv-python
+
+（1）安装paddlepaddle：
+```shell
+# CPU
+pip install paddlepaddle
+# GPU
+pip install paddlepaddle-gpu
+```
+
+（2）安装paddleslim：
+```shell
+https://github.com/PaddlePaddle/PaddleSlim.git
+python setup.py install
+```
+
+（3）安装TensorFlow:
+```shell
+pip install tensorflow == 1.14
+```
+
+（3）安装X2Paddle的1.3.6以上版本：
+```shell
+pip install x2paddle
+```
+
+#### 3.2 准备数据集
+本案例默认以ImageNet1k数据进行自动压缩实验。
+
+#### 3.3 准备预测模型
+
+（1）转换模型
+
+```
+x2paddle --framework=tensorflow --model=tf_model.pb --save_dir=pd_model
+```
+即可得到MobileNetV1模型的预测模型（`model.pdmodel` 和 `model.pdiparams`）。如想快速体验，可直接下载上方表格中MobileNetV1的[Base模型](https://paddle-slim-models.bj.bcebos.com/act/mobilenetv1_inference_model_tf2paddle.tar)。
+
+预测模型的格式为：`model.pdmodel` 和 `model.pdiparams`两个，带`pdmodel`的是模型文件，带`pdiparams`后缀的是权重文件。
+
+### 3.4 自动压缩并产出模型
+
+蒸馏量化自动压缩示例通过run.py脚本启动，会使用接口```paddleslim.auto_compression.AutoCompression```对模型进行自动压缩。配置config文件中模型路径、蒸馏、量化、和训练等部分的参数，配置完成后便可对模型进行量化和蒸馏。具体运行命令为：
+```
+# 单卡
+export CUDA_VISIBLE_DEVICES=0
+python run.py --config_path=./configs/mbv1_qat_dis.yaml --save_dir='./output/'
+```
+
+#### 3.5 测试模型精度
+
+使用eval.py脚本得到模型的mAP：
+```
+export CUDA_VISIBLE_DEVICES=0
+python eval.py --config_path=./configs/mbv1_qat_dis.yaml
+```
+
+## 4.预测部署
