|
||||
## Environmental preparation
|
||||
|
||||
PaddleOCR operating environment and Paddle Serving operating environment are needed.
|
||||
|
||||
1. Please prepare PaddleOCR operating environment reference [link](../../doc/doc_ch/installation.md).
|
||||
|
||||
2. The steps of PaddleServing operating environment prepare are as follows:
|
||||
|
||||
Install serving which used to start the service
|
||||
```
|
||||
pip3 install paddle-serving-server==0.5.0 # for CPU
|
||||
pip3 install paddle-serving-server-gpu==0.5.0 # for GPU
|
||||
# Other GPU environments need to confirm the environment and then choose to execute the following commands
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post9 # GPU with CUDA9.0
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post10 # GPU with CUDA10.0
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post101 # GPU with CUDA10.1 + TensorRT6
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post11 # GPU with CUDA10.1 + TensorRT7
|
||||
```
|
||||
|
||||
3. Install the client to send requests to the service
|
||||
```
|
||||
pip3 install paddle-serving-client==0.5.0 # for CPU
|
||||
|
||||
pip3 install paddle-serving-client-gpu==0.5.0 # for GPU
|
||||
```
|
||||
|
||||
4. Install serving-app
|
||||
```
|
||||
pip3 install paddle-serving-app==0.3.0
|
||||
# fix local_predict to support load dynamic model
|
||||
# find the install directoory of paddle_serving_app
|
||||
vim /usr/local/lib/python3.7/site-packages/paddle_serving_app/local_predict.py
|
||||
# replace line 85 of local_predict.py config = AnalysisConfig(model_path) with:
|
||||
if os.path.exists(os.path.join(model_path, "__params__")):
|
||||
config = AnalysisConfig(os.path.join(model_path, "__model__"), os.path.join(model_path, "__params__"))
|
||||
else:
|
||||
config = AnalysisConfig(model_path)
|
||||
```
|
||||
|
||||
**note:** If you want to install the latest version of PaddleServing, refer to [link](https://github.com/PaddlePaddle/Serving/blob/develop/doc/LATEST_PACKAGES.md).
|
||||
|
||||
|
||||
<a name="model-conversion"></a>
|
||||
## Model conversion
|
||||
When using PaddleServing for service deployment, you need to convert the saved inference model into a serving model that is easy to deploy.
|
||||
|
||||
Firstly, download the [inference model](https://github.com/PaddlePaddle/PaddleOCR#pp-ocr-20-series-model-listupdate-on-dec-15) of PPOCR
|
||||
```
|
||||
# Download and unzip the OCR text detection model
|
||||
wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_det_infer.tar && tar xf ch_ppocr_server_v2.0_det_infer.tar
|
||||
# Download and unzip the OCR text recognition model
|
||||
wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_rec_infer.tar && tar xf ch_ppocr_server_v2.0_rec_infer.tar
|
||||
|
||||
```
|
||||
Then, you can use installed paddle_serving_client tool to convert inference model to server model.
|
||||
```
|
||||
# Detection model conversion
|
||||
python3 -m paddle_serving_client.convert --dirname ./ch_ppocr_server_v2.0_det_infer/ \
|
||||
--model_filename inference.pdmodel \
|
||||
--params_filename inference.pdiparams \
|
||||
--serving_server ./ppocr_det_server_2.0_serving/ \
|
||||
--serving_client ./ppocr_det_server_2.0_client/
|
||||
|
||||
# Recognition model conversion
|
||||
python3 -m paddle_serving_client.convert --dirname ./ch_ppocr_server_v2.0_rec_infer/ \
|
||||
--model_filename inference.pdmodel \
|
||||
--params_filename inference.pdiparams \
|
||||
--serving_server ./ppocr_rec_server_2.0_serving/ \
|
||||
--serving_client ./ppocr_rec_server_2.0_client/
|
||||
|
||||
```
|
||||
|
||||
After the detection model is converted, there will be additional folders of `ppocr_det_server_2.0_serving` and `ppocr_det_server_2.0_client` in the current folder, with the following format:
|
||||
```
|
||||
|- ppocr_det_server_2.0_serving/
|
||||
|- __model__
|
||||
|- __params__
|
||||
|- serving_server_conf.prototxt
|
||||
|- serving_server_conf.stream.prototxt
|
||||
|
||||
|- ppocr_det_server_2.0_client
|
||||
|- serving_client_conf.prototxt
|
||||
|- serving_client_conf.stream.prototxt
|
||||
|
||||
```
|
||||
The recognition model is the same.
|
||||
|
||||

|
||||
## Paddle Serving pipeline deployment
|
||||
|
||||
1. Download the PaddleOCR code, if you have already downloaded it, you can skip this step.
|
||||
```
|
||||
git clone https://github.com/PaddlePaddle/PaddleOCR
|
||||
|
||||
# Enter the working directory
|
||||
cd PaddleOCR/deploy/pdserver/
|
||||
```
|
||||
|
||||
The pdserver directory contains the code to start the pipeline service and send prediction requests, including:
|
||||
```
|
||||
__init__.py
|
||||
config.yml # Start the service configuration file
|
||||
ocr_reader.py # OCR model pre-processing and post-processing code implementation
|
||||
pipeline_http_client.py # Script to send pipeline prediction request
|
||||
web_service.py # Start the script of the pipeline server
|
||||
```
|
||||
|
||||
2. Run the following command to start the service.
|
||||
```
|
||||
# Start the service and save the running log in log.txt
|
||||
python3 web_service.py &>log.txt &
|
||||
```
|
||||
After the service is successfully started, a log similar to the following will be printed in log.txt
|
||||
|
||||
|
||||
3. Send service request
|
||||
```
|
||||
python3 pipeline_http_client.py
|
||||
```
|
||||
After successfully running, the predicted result of the model will be printed in the cmd window. An example of the result is:
|
||||
|
||||
|
||||
<a name="faq"></a>
|
||||
## FAQ
|
||||
**Q1**: No result return after sending the request.
|
||||
|
||||
**A1**: Do not set the proxy when starting the service and sending the request. You can close the proxy before starting the service and before sending the request. The command to close the proxy is:
|
||||
```
|
||||
unset https_proxy
|
||||
unset http_proxy
|
||||
```

|
||||
## 环境准备
|
||||
|
||||
需要准备PaddleOCR的运行环境和Paddle Serving的运行环境。
|
||||
|
||||
- 准备PaddleOCR的运行环境参考[链接](../../doc/doc_ch/installation.md)
|
||||
|
||||
- 准备PaddleServing的运行环境，步骤如下
|
||||
|
||||
1. 安装serving，用于启动服务
|
||||
```
|
||||
pip3 install paddle-serving-server==0.5.0 # for CPU
|
||||
pip3 install paddle-serving-server-gpu==0.5.0 # for GPU
|
||||
# 其他GPU环境需要确认环境再选择执行如下命令
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post9 # GPU with CUDA9.0
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post10 # GPU with CUDA10.0
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post101 # GPU with CUDA10.1 + TensorRT6
|
||||
pip3 install paddle-serving-server-gpu==0.5.0.post11 # GPU with CUDA10.1 + TensorRT7
|
||||
```
|
||||
|
||||
2. 安装client，用于向服务发送请求
|
||||
```
|
||||
pip3 install paddle-serving-client==0.5.0 # for CPU
|
||||
|
||||
pip3 install paddle-serving-client-gpu==0.5.0 # for GPU
|
||||
```
|
||||
|
||||
3. 安装serving-app
|
||||
```
|
||||
pip3 install paddle-serving-app==0.3.0
|
||||
```
|
||||
**note:** 安装0.3.0版本的serving-app后，为了能加载动态图模型，需要修改serving_app的源码，具体为：
|
||||
```
|
||||
# 找到paddle_serving_app的安装目录，找到并编辑local_predict.py文件
|
||||
vim /usr/local/lib/python3.7/site-packages/paddle_serving_app/local_predict.py
|
||||
# 将local_predict.py 的第85行 config = AnalysisConfig(model_path) 替换为：
|
||||
if os.path.exists(os.path.join(model_path, "__params__")):
|
||||
config = AnalysisConfig(os.path.join(model_path, "__model__"), os.path.join(model_path, "__params__"))
|
||||
else:
|
||||
config = AnalysisConfig(model_path)
|
||||
```
|
||||
|
||||
**Note:** 如果要安装最新版本的PaddleServing参考[链接](https://github.com/PaddlePaddle/Serving/blob/develop/doc/LATEST_PACKAGES.md)。
|
||||
|
||||
<a name="模型转换"></a>
|
||||
## 模型转换
|
||||
|
||||
使用PaddleServing做服务化部署时，需要将保存的inference模型转换为serving易于部署的模型。
|
||||
|
||||
首先，下载PPOCR的[inference模型](https://github.com/PaddlePaddle/PaddleOCR#pp-ocr-20-series-model-listupdate-on-dec-15)
|
||||
```
|
||||
# 下载并解压 OCR 文本检测模型
|
||||
wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_det_infer.tar && tar xf ch_ppocr_server_v2.0_det_infer.tar
|
||||
# 下载并解压 OCR 文本识别模型
|
||||
wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_rec_infer.tar && tar xf ch_ppocr_server_v2.0_rec_infer.tar
|
||||
```
|
||||
|
||||
接下来，用安装的paddle_serving_client把下载的inference模型转换成易于server部署的模型格式。
|
||||
|
||||
```
|
||||
# 转换检测模型
|
||||
python3 -m paddle_serving_client.convert --dirname ./ch_ppocr_server_v2.0_det_infer/ \
|
||||
--model_filename inference.pdmodel \
|
||||
--params_filename inference.pdiparams \
|
||||
--serving_server ./ppocr_det_server_2.0_serving/ \
|
||||
--serving_client ./ppocr_det_server_2.0_client/
|
||||
|
||||
# 转换识别模型
|
||||
python3 -m paddle_serving_client.convert --dirname ./ch_ppocr_server_v2.0_rec_infer/ \
|
||||
--model_filename inference.pdmodel \
|
||||
--params_filename inference.pdiparams \
|
||||
--serving_server ./ppocr_rec_server_2.0_serving/ \
|
||||
--serving_client ./ppocr_rec_server_2.0_client/
|
||||
```
|
||||
|
||||
检测模型转换完成后，会在当前文件夹多出`ppocr_det_server_2.0_serving` 和`ppocr_det_server_2.0_client`的文件夹，具备如下格式：
|
||||
```
|
||||
|- ppocr_det_server_2.0_serving/
|
||||
|- __model__
|
||||
|- __params__
|
||||
|- serving_server_conf.prototxt
|
||||
|- serving_server_conf.stream.prototxt
|
||||
|
||||
|- ppocr_det_server_2.0_client
|
||||
|- serving_client_conf.prototxt
|
||||
|- serving_client_conf.stream.prototxt
|
||||
|
||||
```
|
||||
识别模型同理。

|
||||
## Paddle Serving pipeline部署
|
||||
|
||||
1. 下载PaddleOCR代码，若已下载可跳过此步骤
|
||||
```
|
||||
git clone https://github.com/PaddlePaddle/PaddleOCR
|
||||
|
||||
# 进入到工作目录
|
||||
cd PaddleOCR/deploy/pdserver/
|
||||
```
|
||||
pdserver目录包含启动pipeline服务和发送预测请求的代码，包括：
|
||||
```
|
||||
__init__.py
|
||||
config.yml # 启动服务的配置文件
|
||||
ocr_reader.py # OCR模型预处理和后处理的代码实现
|
||||
pipeline_http_client.py # 发送pipeline预测请求的脚本
|
||||
web_service.py # 启动pipeline服务端的脚本
|
||||
```
|
||||
|
||||
2. 启动服务可运行如下命令：
|
||||
```
|
||||
# 启动服务，运行日志保存在log.txt
|
||||
python3 web_service.py &>log.txt &
|
||||
```
|
||||
成功启动服务后，log.txt中会打印类似如下日志
|
||||
|
||||
|
||||
3. 发送服务请求：
|
||||
```
|
||||
python3 pipeline_http_client.py
|
||||
```
|
||||
成功运行后，模型预测的结果会打印在cmd窗口中，结果示例为：
|
||||
|
||||
|
||||
|
||||
<a name="FAQ"></a>
|
||||
## FAQ
|
||||
**Q1**： 发送请求后没有结果返回或者提示输出解码报错
|
||||
|
||||
**A1**： 启动服务和发送请求时不要设置代理，可以在启动服务前和发送请求前关闭代理，关闭代理的命令是：
|
||||
```
|
||||
unset https_proxy
|
||||
unset http_proxy
|
||||
```
