# PaddleClas 服务化部署示例
|
||
|
||
## 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/classification/paddleclas/serving
|
||
|
||
# 下载ResNet50_vd模型文件和测试图片
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/ResNet50_vd_infer.tgz
|
||
tar -xvf ResNet50_vd_infer.tgz
|
||
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
|
||
|
||
# 将配置文件放入预处理目录
|
||
mv ResNet50_vd_infer/inference_cls.yaml models/preprocess/1/inference_cls.yaml
|
||
|
||
# 将模型放入 models/runtime/1目录下, 并重命名为model.pdmodel和model.pdiparams
|
||
mv ResNet50_vd_infer/inference.pdmodel models/runtime/1/model.pdmodel
|
||
mv ResNet50_vd_infer/inference.pdiparams models/runtime/1/model.pdiparams
|
||
|
||
# 拉取fastdeploy镜像
|
||
# GPU镜像
|
||
docker pull paddlepaddle/fastdeploy:0.6.0-gpu-cuda11.4-trt8.4-21.10
|
||
# CPU镜像
|
||
docker pull paddlepaddle/fastdeploy:0.6.0-cpu-only-21.10
|
||
|
||
# 运行容器.容器名字为 fd_serving, 并挂载当前目录为容器的 /serving 目录
|
||
nvidia-docker run -it --net=host --name fd_serving -v `pwd`/:/serving paddlepaddle/fastdeploy:0.6.0-gpu-cuda11.4-trt8.4-21.10 bash
|
||
|
||
# 启动服务(不设置CUDA_VISIBLE_DEVICES环境变量，会拥有所有GPU卡的调度权限)
|
||
CUDA_VISIBLE_DEVICES=0 fastdeployserver --model-repository=/serving/models --backend-config=python,shm-default-byte-size=10485760
|
||
```
|
||
>> **注意**:
|
||
|
||
>> 拉取其他硬件上的镜像请看[服务化部署主文档](../../../../../serving/README.md)
|
||
|
||
>> 执行fastdeployserver启动服务出现"Address already in use", 请使用`--grpc-port`指定端口号来启动服务，同时更改客户端示例中的请求端口号.
|
||
|
||
>> 其他启动参数可以使用 fastdeployserver --help 查看
|
||
|
||
服务启动成功后， 会有以下输出:
|
||
```
|
||
......
|
||
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
|
||
```
|
||
|
||
|
||
## 客户端请求
|
||
|
||
在物理机器中执行以下命令，发送grpc请求并输出结果
|
||
```
|
||
#下载测试图片
|
||
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
|
||
|
||
#安装客户端依赖
|
||
python3 -m pip install tritonclient\[all\]
|
||
|
||
# 发送请求
|
||
python3 paddlecls_grpc_client.py
|
||
```
|
||
|
||
发送请求成功后，会返回json格式的检测结果并打印输出:
|
||
```
|
||
output_name: CLAS_RESULT
|
||
{'label_ids': [153], 'scores': [0.6862289905548096]}
|
||
```
|
||
|
||
## 配置修改
|
||
|
||
当前默认配置在GPU上运行TensorRT引擎， 如果要在CPU或其他推理引擎上运行。 需要修改`models/runtime/config.pbtxt`中配置，详情请参考[配置文档](../../../../../serving/docs/zh_CN/model_configuration.md)
