# encode(to:inputs:results:executionDescriptor:)

Runs the graph for the given feeds and returns the target tensor values, ensuring all target operations also executed. This call is asynchronous and will return immediately after finishing encoding.

## Declaration

```swift
func encode(to commandBuffer: MPSCommandBuffer, inputs inputsArray: [MPSGraphTensorData], results resultsArray: [MPSGraphTensorData]?, executionDescriptor: MPSGraphExecutableExecutionDescriptor?) -> [MPSGraphTensorData]
```

## Parameters

- `commandBuffer`: CommandBuffer passed to exectute the graph on, commitAndContinue might be called, please don’t rely on underlying MTLCommandBuffer to remain uncommitted
- `inputsArray`: Feeds tensorData for the placeholder tensors, same order as arguments of main function
- `resultsArray`: Tensors for which the caller wishes MPSGraphTensorData to be returned
- `executionDescriptor`: ExecutionDescriptor to be passed in and used,

## Return Value

Return Value A valid MPSGraphTensorData array with results synchronized to the CPU memory if MPSGraphOptionsSynchronizeResults set.
