# variable(with:shape:dataType:name:)

Creates a variable operation and returns the result tensor.

```
func variable(with data: Data, shape: [NSNumber], dataType: MPSDataType, name: String?) -> MPSGraphTensor
```

## Parameters

`data`

The data for the tensor. The number of bytes should be sizeof(dataType)numberOfElements.

`shape`

The shape of the output tensor. This has to be statically shaped.

`dataType`

The dataType of the constant tensor.

`name`

The name for the operation.

## Return Value

A valid MPSGraphTensor object.
