# MPSGraphDepthwiseConvolution2DOpDescriptor

A class that defines the parameters for  a 2D-depthwise convolution operation.

## Declaration

```swift
class MPSGraphDepthwiseConvolution2DOpDescriptor
```

## Overview

Overview An MPSGraphDepthwiseConvolution2DOpDescriptor defines constant parameters for 2D-depthwise convolutions. Use this class with depthwiseConvolution2D(_:weights:descriptor:name:), depthwiseConvolution2DDataGradient(_:weights:outputShape:descriptor:name:), and depthwiseConvolution2DWeightsGradient(_:source:outputShape:descriptor:name:) methods.
