### Start React Demo Project

Source: https://cloud.baidu.com/doc/AI_DH/s/bmg52lb7y

Starts the React version of the demo project. This command compiles the project and launches a development server, typically serving the application at a local address. It assumes all dependencies have been installed.

```bash
npm run start

```

--------------------------------

### Compile and Run Demo

Source: https://cloud.baidu.com/doc/EASYDL/s/Dl6c0uoue

Instructions for compiling the SDK demo and running it with example commands.

```APIDOC
## Compile and Run Demo

Model resource files are pre-packaged in the SDK. The demo project can be compiled and run directly.

### Compilation and Execution

```bash
1cd src
2mkdir build && cd build
3cmake ..
4make
# make install is optional, or add the lib path to environment variables
6sudo make install
7sudo ldconfig
8./demo_batch_inference/easyedge_batch_inference {model RES folder}  {test image path or folder path containing only images} {serial number}
```

### Demo Run Example

```bash
1baidu@nano:~/ljay/easydl/sdk/demo/build$ ./demo_batch_inference/easyedge_batch_inference ../../../../RES/ /ljay/images/mix008.jpeg

```

### Test Demo HTTP Service

After compiling the demo, an HTTP service is generated. Run the following command:

```bash
1# ./easyedge_serving {res_dir} {serial_key} {host, default 0.0.0.0} {port, default 24401}
2 ./easyedge_serving ../../../../RES "1111-1111-1111-1111" 0.0.0.0  24401
```

The log will display:

```bash
1HTTP is now serving at 0.0.0.0:24401
```

You can then open a browser to `http://{device_ip}:24401` to test by selecting images. You can also access the service via HTTP API calls (refer to the API description below).

### Integration Instructions

This method involves embedding the runtime library into your application.

#### Usage Flow

Refer to the demo usage flow first. For errors, consult the file comments and log explanations.

```cpp
1// step 1: Configure model runtime parameters
2EdgePredictorConfig config;
3config.model_dir = model_dir;
4config.set_config(params::PREDICTOR_KEY_SERIAL_NUM, serial_num);
5config.set_config(params::PREDICTOR_KEY_GTURBO_MAX_BATCH_SIZE, 1);  // Maximum batch size supported by the optimized model; actual inference images per batch cannot exceed this value
6config.set_config(params::PREDICTOR_KEY_GTURBO_FP16, false);        // Set to true to enable faster fp16 mode inference; precision may slightly decrease. Depends on hardware support; not all models support fp16. Refer to documentation.
7config.set_config(params::PREDICTOR_KEY_GTURBO_COMPILE_LEVEL, 1);   // Model compilation strategy. If max_batch_size differs from historical compilation, recompile the model.
8
9
10// step 2: Create and initialize Predictor
11auto predictor = global_controller()->CreateEdgePredictor<EdgePredictorConfig>(config);
12if (predictor->init() != EDGE_OK) {
13    exit(-1);
14}
15
16// step 3-1: Infer image
17auto img = cv::imread({image path});
18std::vector<EdgeResultData> results;
19predictor->infer(img, results);
20
21// step 3-2: Infer video
22std::vector<EdgeResultData> results;
23FrameTensor frame_tensor;
24VideoConfig video_config;
25video_config.source_type = static_cast<SourceType>(video_type);  // Source type definition reference: easyedge_video.h
26video_config.source_value = video_src;
27/*
28... more video_configs, configure as needed
29*/
30auto video_decoding = CreateVideoDecoding(video_config);
31while (video_decoding->next(frame_tensor) == EDGE_OK) {
32    results.clear();
33    if (frame_tensor.is_needed) {
34        predictor->infer(frame_tensor.frame, results);
35        render(frame_tensor.frame, results, predictor->model_info().kind);
36    }
37    //video_decoding->display(frame_tensor); // Display current frame, requires configuration in video_config
38    //video_decoding->save(frame_tensor); // Save current frame to video, requires configuration in video_config
39 }
```
```
