# Install Paddle Serving with Docker

([简体中文](./Install_CN.md)|English)

**Strongly recommend** you build **Paddle Serving** in Docker. For more images, please refer to [Docker Image List](Docker_Images_CN.md).

**Tip-1**: This project only supports <mark>**Python3.6/3.7/3.8/3.9**</mark>, all subsequent operations related to Python/Pip need to select the correct Python version.

**Tip-2**: The GPU environments in the following examples are all cuda10.2-cudnn7. If you use Python Pipeline to deploy and need Nvidia TensorRT to optimize prediction performance, please refer to [Supported Mirroring Environment and Instructions](#4.-Supported-Docker-Images-and-Instruction) to choose other versions.

## 1. Start the Docker Container
<mark>**Both Serving Dev Image and Paddle Dev Image are supported at the same time. You can choose 1 from the operation 2 in chapters 1.1 and 1.2.**</mark>Deploying the Serving service on the Paddle docker image requires the installation of additional dependency libraries. Therefore, we directly use the Serving development image.

### 1.1 Serving Dev Images (CPU/GPU 2 choose 1)
**CPU:**
```
# Start CPU Docker Container
docker pull registry.baidubce.com/paddlepaddle/serving:0.8.0-devel
docker run -p 9292:9292 --name test -dit registry.baidubce.com/paddlepaddle/serving:0.8.0-devel bash
docker exec -it test bash
git clone https://github.com/PaddlePaddle/Serving
```
**GPU:**
```
# Start GPU Docker Container
docker pull registry.baidubce.com/paddlepaddle/serving:0.8.0-cuda10.2-cudnn7-devel
nvidia-docker run -p 9292:9292 --name test -dit registry.baidubce.com/paddlepaddle/serving:0.8.0-cuda10.2-cudnn7-devel bash
nvidia-docker exec -it test bash
git clone https://github.com/PaddlePaddle/Serving
```
### 1.2 Paddle Dev Images (choose any codeblock of CPU/GPU)
**CPU:**
```
# Start CPU Docker Container
docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.2
docker run -p 9292:9292 --name test -dit registry.baidubce.com/paddlepaddle/paddle:2.2.2 bash
docker exec -it test bash
git clone https://github.com/PaddlePaddle/Serving

# Paddle dev image needs to run the following script to increase the dependencies required by Serving
bash Serving/tools/paddle_env_install.sh
```
**GPU:**
```
# Start GPU Docker
nvidia-docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.2-gpu-cuda10.2-cudnn7
nvidia-docker run -p 9292:9292 --name test -dit registry.baidubce.com/paddlepaddle/paddle:2.2.2-gpu-cuda10.2-cudnn7 bash
nvidia-docker exec -it test bash
git clone https://github.com/PaddlePaddle/Serving

# Paddle development image needs to execute the following script to increase the dependencies required by Serving
bash Serving/tools/paddle_env_install.sh
```

## 2. Install Paddle Serving stable wheel packages

Install the required pip dependencies
```
cd Serving
pip3 install -r python/requirements.txt
```

Install the service whl package. There are three types of client, app and server. The server is divided into CPU and GPU. Choose one installation according to the environment. 
- post102 = CUDA10.2 + Cudnn7 + TensorRT6(Recommended)
- post101 = CUDA10.1 + cuDNN7 + TensorRT6
- post112 = CUDA11.2 + cuDNN8 + TensorRT8

```shell
pip3 install paddle-serving-client==0.8.3 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip3 install paddle-serving-app==0.8.3 -i https://pypi.tuna.tsinghua.edu.cn/simple

# CPU Server
pip3 install paddle-serving-server==0.8.3 -i https://pypi.tuna.tsinghua.edu.cn/simple

# GPU environments need to confirm the environment before choosing which one to execute
pip3 install paddle-serving-server-gpu==0.8.3.post102 -i https://pypi.tuna.tsinghua.edu.cn/simple 
pip3 install paddle-serving-server-gpu==0.8.3.post101 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip3 install paddle-serving-server-gpu==0.8.3.post112 -i https://pypi.tuna.tsinghua.edu.cn/simple
```

By default, the domestic Tsinghua mirror source is turned on to speed up the download. If you use a proxy, you can turn it off（`-i https://pypi.tuna.tsinghua.edu.cn/simple`).

If you need to use the installation package compiled by the develop branch, please download the download address from [Download wheel packages](./Latest_Packages_EN.md), and use the `pip install` command to install. If you want to compile by yourself, please refer to [Paddle Serving Compilation Document](./Compile_CN.md).

The paddle-serving-server and paddle-serving-server-gpu installation packages support Centos 6/7, Ubuntu 16/18 and Windows 10.

The paddle-serving-client and paddle-serving-app installation packages support Linux and Windows, and paddle-serving-client only supports python3.6/3.7/3.8/3.9.

**If you used the CUDA10.2 environment of paddle serving 0.5.X 0.6.X before, you need to pay attention to version 0.8.0, paddle-serving-server-gpu==0.8.0.post102 uses Cudnn7 and TensorRT6, and 0.6.0.post102 uses cudnn8 and TensorRT7. If 0.6.0 cuda10.2 users need to upgrade, please use paddle-serving-server-gpu==0.8.0.post1028**

## 3. Install Paddle related Python libraries
**You only need to install it when you use the `paddle_serving_client.convert` command or the `Python Pipeline framework`. **
```
# CPU environment please execute
pip3 install paddlepaddle==2.2.2 -i https://pypi.tuna.tsinghua.edu.cn/simple

# GPU CUDA 10.2 environment please execute
pip3 install paddlepaddle-gpu==2.2.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
```
**Note**: If your CUDA version is not 10.2 or if you want to use TensorRT(CUDA10.2 included), please do not execute the above commands directly, you need to refer to [Paddle-Inference official document-download and install the Linux prediction library](https://paddleinference.paddlepaddle.org.cn/master/user_guides/download_lib.html#python) Select the URL link of the corresponding GPU environment and install it. Assuming that you use Python3.6, please follow the codeblock.

```
