-## 介绍
-复杂的模型有利于提高模型的性能，但也导致模型中存在一定冗余，模型量化将全精度缩减到定点数减少这种冗余，达到减少模型计算复杂度，提高模型推理性能的目的。
-模型量化可以在基本不损失模型的精度的情况下，将FP32精度的模型参数转换为Int8精度，减小模型参数大小并加速计算，使用量化后的模型在移动端等部署时更具备速度优势。
-
-本教程将介绍如何使用飞桨模型压缩库PaddleSlim做PaddleOCR模型的压缩。
-[PaddleSlim](https://github.com/PaddlePaddle/PaddleSlim) 集成了模型剪枝、量化（包括量化训练和离线量化）、蒸馏和神经网络搜索等多种业界常用且领先的模型压缩功能，如果您感兴趣，可以关注并了解。
-
-在开始本教程之前，建议先了解[PaddleOCR模型的训练方法](../../../doc/doc_ch/quickstart.md)以及[PaddleSlim](https://paddleslim.readthedocs.io/zh_CN/latest/index.html)
-
-
-## 快速开始
-量化多适用于轻量模型在移动端的部署，当训练出一个模型后，如果希望进一步的压缩模型大小并加速预测，可使用量化的方法压缩模型。
-
-模型量化主要包括五个步骤：
-1. 安装 PaddleSlim
-2. 准备训练好的模型
-3. 量化训练
-4. 导出量化推理模型
-5. 量化模型预测部署
-
-### 1. 安装PaddleSlim
-
-```bash
-git clone https://github.com/PaddlePaddle/PaddleSlim.git
-cd Paddleslim
-python setup.py install
-```
-
-### 2. 准备训练好的模型
-
-PaddleOCR提供了一系列训练好的[模型](../../../doc/doc_ch/models_list.md)，如果待量化的模型不在列表中，需要按照[常规训练](../../../doc/doc_ch/quickstart.md)方法得到训练好的模型。
-
-### 3. 量化训练
-量化训练包括离线量化训练和在线量化训练，在线量化训练效果更好，需加载预训练模型，在定义好量化策略后即可对模型进行量化。
-
-
-量化训练的代码位于slim/quantization/quant.py 中，比如训练检测模型，训练指令如下：
-```bash
-python deploy/slim/quantization/quant.py -c configs/det/det_mv3_db.yml -o Global.pretrain_weights='your trained model'   Global.save_model_dir=./output/quant_model
-
-# 比如下载提供的训练模型
-wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_mobile_v2.0_det_train.tar
-tar -xf ch_ppocr_mobile_v2.0_det_train.tar
-python deploy/slim/quantization/quant.py -c configs/det/det_mv3_db.yml -o Global.pretrain_weights=./ch_ppocr_mobile_v2.0_det_train/best_accuracy   Global.save_inference_dir=./output/quant_inference_model
-
-```
-如果要训练识别模型的量化，修改配置文件和加载的模型参数即可。
-
-### 4. 导出模型
-
-在得到量化训练保存的模型后，我们可以将其导出为inference_model，用于预测部署：
-
-```bash
-python deploy/slim/quantization/export_model.py -c configs/det/det_mv3_db.yml -o Global.checkpoints=output/quant_model/best_accuracy Global.save_model_dir=./output/quant_inference_model
-```
-
-### 5. 量化模型部署
-
-上述步骤导出的量化模型，参数精度仍然是FP32，但是参数的数值范围是int8，导出的模型可以通过PaddleLite的opt模型转换工具完成模型转换。
-量化模型部署的可参考 [移动端模型部署](../../lite/readme.md)

-## Introduction
-
-Generally, a more complex model would achive better performance in the task, but it also leads to some redundancy in the model.
-Quantization is a technique that reduces this redundancy by reducing the full precision data to a fixed number,
-so as to reduce model calculation complexity and improve model inference performance.
-
-This example uses PaddleSlim provided [APIs of Quantization](https://paddlepaddle.github.io/PaddleSlim/api/quantization_api/) to compress the OCR model.
-
-It is recommended that you could understand following pages before reading this example：
-- [The training strategy of OCR model](../../../doc/doc_en/quickstart_en.md)
-- [PaddleSlim Document](https://paddlepaddle.github.io/PaddleSlim/api/quantization_api/)
-
-## Quick Start
-Quantization is mostly suitable for the deployment of lightweight models on mobile terminals.
-After training, if you want to further compress the model size and accelerate the prediction, you can use quantization methods to compress the model according to the following steps.
-
-1. Install PaddleSlim
-2. Prepare trained model
-3. Quantization-Aware Training
-4. Export inference model
-5. Deploy quantization inference model
-
-
-### 1. Install PaddleSlim
-
-```bash
-git clone https://github.com/PaddlePaddle/PaddleSlim.git
-cd Paddleslim
-python setup.py install
-```
-
-
-### 2. Download Pretrain Model
-PaddleOCR provides a series of trained [models](../../../doc/doc_en/models_list_en.md).
-If the model to be quantified is not in the list, you need to follow the [Regular Training](../../../doc/doc_en/quickstart_en.md) method to get the trained model.
-
-
-### 3. Quant-Aware Training
-Quantization training includes offline quantization training and online quantization training.
-Online quantization training is more effective. It is necessary to load the pre-training model.
-After the quantization strategy is defined, the model can be quantified.
-
-The code for quantization training is located in `slim/quantization/quant.py`. For example, to train a detection model, the training instructions are as follows:
-```bash
-python deploy/slim/quantization/quant.py -c configs/det/det_mv3_db.yml -o Global.pretrain_weights='your trained model'   Global.save_model_dir=./output/quant_model
-
-# download provided model
-wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_mobile_v2.0_det_train.tar
-tar -xf ch_ppocr_mobile_v2.0_det_train.tar
-python deploy/slim/quantization/quant.py -c configs/det/det_mv3_db.yml -o Global.pretrain_weights=./ch_ppocr_mobile_v2.0_det_train/best_accuracy   Global.save_model_dir=./output/quant_model
-
-```
-
-
-### 4. Export inference model
-
-After getting the model after pruning and finetuning we, can export it as inference_model for predictive deployment:
-
-```bash
-python deploy/slim/quantization/export_model.py -c configs/det/det_mv3_db.yml -o Global.checkpoints=output/quant_model/best_accuracy Global.save_inference_dir=./output/quant_inference_model
-```
-
-### 5. Deploy
-The numerical range of the quantized model parameters derived from the above steps is still FP32, but the numerical range of the parameters is int8.
-The derived model can be converted through the `opt tool` of PaddleLite.
-
-For quantitative model deployment, please refer to [Mobile terminal model deployment](../../lite/readme_en.md)
