# compile(options:device:inputTensors:inputTensorsData:)

Compiles the inference graph for the options, device, and input tensors you specify.

## Declaration

```swift
func compile(options: MLCGraphCompilationOptions = [], device: MLCDevice, inputTensors: [String : MLCTensor]?, inputTensorsData: [String : MLCTensorData]?) -> Bool
```

## Parameters

- `options`: The compiler options.
- `device`: The device.
- `inputTensors`: The list of input tensors that are constants.
- `inputTensorsData`: The tensor data to use with the input tensors.

## Return Value

Return Value A Boolean that indicates success or failure.

## Discussion

Discussion If you specify the list of constant tensors before the framework compiles the graph, then the framework can perform additional optimizations during the compilation.
