## init

```java
public boolean init()
```

Configuration parameter initialization for parallel inference.

- Returns

  Whether the initialization is successful.

```java
public boolean init(MSContext msContext)
```

Configuration parameter initialization for parallel inference.

- Parameters

    - `msContext`: Context configuration for concurrent inference runtime.

- Returns

  Whether the initialization is successful.

## setWorkerNum

```java
public void setWorkerNum(int workerNum)
```

The parameter setting of the number of models in parallel inference.

- Parameters

    - `workerNum`: Set the number of models in the configuration.

## setConfigInfo

```java
public void setConfigInfo(String section, HashMap<String, String> config)
```

Model configuration parameter settings in parallel inference.

- Parameters

    - `section`: Configured chapter name.
    - `config`: config pair to update.

## setConfigPath

```java
public void setConfigPath(String configPath)
```

Set the configuration file path in concurrent inference.

- Parameters

    - `configPath`: config path.

## getConfigPath

```java
public String getConfigPath()
```

Get the path to the configuration file set in RunnerConfig.

- Returns

  config path.

## getRunnerConfigPtr

```java
public long getRunnerConfigPtr()
```

Get a pointer to the underlying concurrent inference configuration parameters.

- Returns

  Low-level concurrent inference configuration parameter pointer.

## setDeviceIds

```java
public void setDeviceIds(ArrayList<Integer> deviceIds)
```

Set the list of device id in concurrent inference.

- Parameters

    - `deviceIds`: list of device id.

## getDeviceIds
