# auxiliaryPlanes

The auxiliary plane configurations for this tensor.

## Declaration

```swift
var auxiliaryPlanes: MTLTensorAuxiliaryPlaneDescriptorMap? { get set }
```

## Discussion

Discussion Set this property with a populated MTLTensorAuxiliaryPlaneDescriptorMap to create a multi-plane tensor. When nil, the tensor has only a data plane. Multi-plane tensors do not support machineLearning. Use compute or render. Multi-plane tensors do not support data types larger than one byte as the data plane type The default value is nil.
