# executeForward(batchSize:options:outputsData:)

Executes the forward pass of the training graph with the batch size, execution options, and output data you specify.

## Declaration

```swift
@discardableResult func executeForward(batchSize: Int, options: MLCExecutionOptions = [], outputsData: [String : MLCTensorData]? = nil) async throws -> (result: MLCTensor?, executionTime: TimeInterval)
```

## Parameters

- `batchSize`: The batch size.
- `options`: The execution options.
- `outputsData`: A dictionary that contains output data.

## Return Value

Return Value The result tensor, if any, and the execution time if you specify profiling.
