# MPSGraphDepthwiseConvolution3DOpDescriptor

The class that defines the parameters for a 3D-depthwise convolution operation.

## Declaration

```swift
class MPSGraphDepthwiseConvolution3DOpDescriptor
```

## Overview

Overview A MPSGraphDepthwiseConvolution3DOpDescriptor defines constant parameters for 3D depthwise convolutions. Use this class with depthwiseConvolution3D(_:weights:descriptor:name:), depthwiseConvolution3DDataGradient(_:weights:outputShape:descriptor:name:) and depthwiseConvolution3DWeightsGradient(_:source:outputShape:descriptor:name:) methods.
