# restoreTrainingSession(sessionParameters:)

Creates an asynchronous training session for a sound classifier by restoring an existing training session’s state from its parameters.

## Declaration

```swift
static func restoreTrainingSession(sessionParameters: MLTrainingSessionParameters) throws -> MLTrainingSession<MLSoundClassifier>
```

## Parameters

- `sessionParameters`: The doc://com.apple.createml/documentation/CreateML/MLTrainingSessionParameters instance you used to create the training session using doc://com.apple.createml/documentation/CreateML/MLSoundClassifier/makeTrainingSession(trainingData:parameters:sessionParameters:).

## Return Value

Return Value An MLTrainingSession that represents the sound classifier training session.
