# MPSGraphPooling4DOpDescriptor

The class that defines the parameters for a 4D pooling operation.

## Declaration

```swift
class MPSGraphPooling4DOpDescriptor
```

## Overview

Overview Use this descriptor with the following methods: maxPooling4D(_:descriptor:name:) maxPooling4DReturnIndices(_:descriptor:name:) maxPooling4DGradient(_:source:descriptor:name:) maxPooling4DGradient(withGradientTensor:indicesTensor:outputShape:descriptor:name:) maxPooling4DGradient(withGradientTensor:indicesTensor:outputShapeTensor:descriptor:name:) avgPooling4D(_:descriptor:name:) avgPooling4DGradient(_:source:descriptor:name:) L2NormPooling4D(_:descriptor:name:) L2NormPooling4DGradient(_:source:descriptor:name:)
