# makeTrainingSession(trainingData:parameters:sessionParameters:)

Creates an asynchronous hand pose classifier’s training session.

```
static func makeTrainingSession(trainingData: MLHandPoseClassifier.DataSource, parameters: MLHandPoseClassifier.ModelParameters = .init(), sessionParameters: MLTrainingSessionParameters = _defaultSessionParameters) throws -> MLTrainingSession<MLHandPoseClassifier>
```

## Parameters

`trainingData`

An [`MLHandPoseClassifier.DataSource`](/documentation/CreateML/MLHandPoseClassifier/DataSource) instance.

`parameters`

An [`MLHandPoseClassifier.ModelParameters`](/documentation/CreateML/MLHandPoseClassifier/ModelParameters-swift.struct)
instance you use to configure the model for the training session.

`sessionParameters`

An [`MLTrainingSessionParameters`](/documentation/CreateML/MLTrainingSessionParameters) instance you use
to configure the training session.

## Return Value

An [`MLTrainingSession`](/documentation/CreateML/MLTrainingSession) that represents the action
classifier training session.
