# PaddleServing预测功能测试

PaddleServing预测功能测试的主程序为`test_inference_serving.sh`，可以测试基于PaddleServing的部署功能。

## 1. 测试结论汇总

基于训练是否使用量化，进行本测试的模型可以分为`正常模型`和`量化模型`，这两类模型对应的C++预测功能汇总如下：

| 模型类型 |device | batchsize | tensorrt | mkldnn | cpu多线程 |
|  ----   |  ---- |   ----   |  :----:  |   :----:   |  :----:  |
| 正常模型 | GPU | 1/6 | fp32/fp16 | - | - |
| 正常模型 | CPU | 1/6 | - | fp32 | 支持 |
| 量化模型 | GPU | 1/6 | int8 | - | - |
| 量化模型 | CPU | 1/6 | - | int8 | 支持 |

## 2. 测试流程
### 2.1 功能测试
先运行`prepare.sh`准备数据和模型，然后运行`test_inference_serving.sh`进行测试，最终在```PTDN/output```目录下生成`serving_infer_*.log`后缀的日志文件。

```shell
bash PTDN/prepare.sh ./PTDN/configs/ppocr_det_mobile_params.txt "serving_infer"

# 用法:
bash PTND/test_inference_serving.sh ./PTDN/configs/ppocr_det_mobile_params.txt
```  

#### 运行结果

各测试的运行情况会打印在 `PTDN/output/results_serving.log` 中：
运行成功时会输出：

```
Run successfully  with command - python3.7 pipeline_http_client.py --image_dir=../../doc/imgs > ../../tests/output/server_infer_cpu_usemkldnn_True_threads_1_batchsize_1.log 2>&1 !
Run successfully  with command - xxxxx
...
```

运行失败时会输出：

```
Run failed with command - python3.7 pipeline_http_client.py --image_dir=../../doc/imgs > ../../tests/output/server_infer_cpu_usemkldnn_True_threads_1_batchsize_1.log 2>&1 !
Run failed with command - python3.7 pipeline_http_client.py --image_dir=../../doc/imgs > ../../tests/output/server_infer_cpu_usemkldnn_True_threads_6_batchsize_1.log 2>&1 !
Run failed with command - xxxxx
...
```

详细的预测结果会存在 PTDN/output/ 文件夹下，例如`server_infer_gpu_usetrt_True_precision_fp16_batchsize_1.log`中会返回检测框的坐标:
