# PaddleOCR Python轻量服务化部署示例
|
|
|
|
|
|
|
|
|
|
|
|
PaddleOCR Python轻量服务化部署是FastDeploy基于Flask框架搭建的可快速验证线上模型部署可行性的服务化部署示例，基于http请求完成AI推理任务，适用于无并发推理的简单场景，如有高并发，高吞吐场景的需求请参考[fastdeploy_serving](../fastdeploy_serving/)

|
## 1. 部署环境准备
|
|
|
|
|
|
|
|
|
|
|
|
在部署前，需确认软硬件环境，同时下载预编译python wheel 包，参考文档[FastDeploy预编译库安装](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#FastDeploy预编译库安装)
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
## 2. 启动服务
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# 下载部署示例代码
|
|
|
|
|
|
git clone https://github.com/PaddlePaddle/FastDeploy.git
|
|
|
|
|
|
cd FastDeploy/examples/vision/ocr/PP-OCR/serving/simple_serving
|
|
|
|
|
|
|
|
|
|
|
|
# 如果您希望从PaddleOCR下载示例代码，请运行
|
|
|
|
|
|
git clone https://github.com/PaddlePaddle/PaddleOCR.git
|
|
|
|
|
|
# 注意：如果当前分支找不到下面的fastdeploy测试代码，请切换到dygraph分支
|
|
|
|
|
|
git checkout dygraph
|
|
|
|
|
|
cd PaddleOCR/deploy/fastdeploy/serving/simple_serving
|
|
|
|
|
|
|
|
|
|
|
|
# 下载模型和字典文件
|
|
|
|
|
|
wget https://paddleocr.bj.bcebos.com/PP-OCRv3/chinese/ch_PP-OCRv3_det_infer.tar
|
|
|
|
|
|
tar xvf ch_PP-OCRv3_det_infer.tar
|
|
|
|
|
|
|
|
|
|
|
|
wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_mobile_v2.0_cls_infer.tar
|
|
|
|
|
|
tar -xvf ch_ppocr_mobile_v2.0_cls_infer.tar
|
|
|
|
|
|
|
|
|
|
|
|
wget https://paddleocr.bj.bcebos.com/PP-OCRv3/chinese/ch_PP-OCRv3_rec_infer.tar
|
|
|
|
|
|

|
|
wget https://gitee.com/paddlepaddle/PaddleOCR/raw/release/2.6/ppocr/utils/ppocr_keys_v1.txt
|
|
|
|
|
|
|
|
|
|
|
|
# 启动服务，可修改server.py中的配置项来指定硬件、后端等
|
|
|
|
|
|
# 可通过--host、--port指定IP和端口号
|
|
|
|
|
|
fastdeploy simple_serving --app server:app
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 3. 客户端请求
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# 下载部署示例代码
|
|
|
|
|
|
git clone https://github.com/PaddlePaddle/PaddleOCR.git
|
|
|
|
|
|
cd PaddleOCR/deploy/fastdeploy/serving/simple_serving
|
|
|
|
|
|
|
|
|
|
|
|
# 下载测试图片
|
|
|
|
|
|
wget https://gitee.com/paddlepaddle/PaddleOCR/raw/release/2.6/doc/imgs/12.jpg
|
|
|
|
|
|
|
|
|
|
|
|
# 请求服务，获取推理结果（如有必要，请修改脚本中的IP和端口号）
|
|
|
|
|
|
python client.py
|
|
|
|
|
|
```
|
