# init(forModelAt:trainingData:configuration:completionHandler:)

Creates a task that updates the model at the URL with the training data and configuration, and calls the completion handler when the update completes.

## Declaration

```swift
convenience init(forModelAt modelURL: URL, trainingData: any MLBatchProvider, configuration: MLModelConfiguration?, completionHandler: @escaping (MLUpdateContext) -> Void) throws
```

## Parameters

- `modelURL`: The location in the file system of a model file (ModelName.mlmodelc).
- `trainingData`: The update data for the model, contained in a batch provider.
- `configuration`: The model settings for an updated model object.
- `completionHandler`: The closure the task calls when it finishes.
