# Example of UIE Serving Deployment

Before serving deployment, you need to confirm:

- 1. You can refer to [FastDeploy服务化部署](../../../../../serving/README_CN.md) for hardware and software environment requirements and image pull commands for serving images.

## Prepare models

Download the UIE-Base model (if you have trained models, skip this step):
```bash
# Download UIE model documents and vocabulary. Taking the uie-base model as an example
wget https://bj.bcebos.com/fastdeploy/models/uie/uie-base.tgz
tar -xvfz uie-base.tgz

# Move the model to the model repository directory
mv uie-base/* models/uie/1/
```

After download and move, the models directory is as follows:

```
models
└── uie
    ├── 1
    │   ├── inference.pdiparams
    │   ├── inference.pdmodel
    │   ├── model.py
    │   └── vocab.txt
    └── config.pbtxt
```

## Pull and run images.
```bash
# x.y.z represent image versions. You can refer to the serving documents to replace them with numbers
# GPU Image
docker pull paddlepaddle/fastdeploy:x.y.z-gpu-cuda11.4-trt8.4-21.10
# CPU Image
docker pull paddlepaddle/fastdeploy:x.y.z-cpu-only-21.10

# Run the container. The container name is fd_serving, and the current directory is mounted as the container's /uie_serving directory
docker run  -it --net=host --name fastdeploy_server --shm-size="1g" -v `pwd`/:/uie_serving paddlepaddle/fastdeploy:x.y.z-gpu-cuda11.4-trt8.4-21.10 bash

# Start the service (it will have scheduling privileges for all GPU cards without setting the CUDA_VISIBLE_DEVICES environment variable)
CUDA_VISIBLE_DEVICES=0 fastdeployserver --model-repository=/uie_serving/models --backend-config=python,shm-default-byte-size=10485760
```

>> **Attention**: When appearing "Address already in use", please use `--grpc-port`specified port numbers to start the service. Meanwhile you should change the requesting port numbers in grpc_client.py

When starting the service, the following output will be displayed:
```
......
I0928 04:51:15.784517 206 grpc_server.cc:4117] Started GRPCInferenceService at 0.0.0.0:8001
I0928 04:51:15.785177 206 http_server.cc:2815] Started HTTPService at 0.0.0.0:8000
I0928 04:51:15.826578 206 http_server.cc:167] Started Metrics Service at 0.0.0.0:8002
```


## Client Requests
Client requests can execute script requests locally and in the container.

Dependencies should be installed to execute the script locally:
```
pip install grpcio
pip install tritonclient[all]

# If bash cannot recognize the brackets, you can use the following command to install dependencies:
pip install tritonclient\[all\]

# Send Requests
python3 grpc_client.py
```

When the request is sent successfully, the result is returned and printed out:

## Configuration Modification

The current configuration is by default to run the paddle engine on CPU. If you want to run on CPU/GPU or other inference engines, modifying the configuration is needed.Please refer to [配置文档](../../../../serving/docs/zh_CN/model_configuration.md)
