# depthwiseConvolution2DDataGradient(_:weights:outputShape:descriptor:name:)

Creates a 2D-depthwise convolution gradient for data operation and returns the result tensor.

```
func depthwiseConvolution2DDataGradient(_ incomingGradient: MPSGraphTensor, weights: MPSGraphTensor, outputShape: [NSNumber], descriptor: MPSGraphDepthwiseConvolution2DOpDescriptor, name: String?) -> MPSGraphTensor
```

## Parameters

`incomingGradient`

A 2D input gradient tensor - must be of rank=4. The layout is defined by `descriptor.dataLayout`.

`weights`

The weights tensor, must be rank=4. The layout is defined by `descriptor.weightsLayout`.

`outputShape`

The shape of the οutput tensor (and therefore input tensor of forward pass).

`descriptor`

The descriptor object that specifies strides, dilation rates, paddings and layouts.

`name`

The name for the operation.

## Return Value

A valid MPSGraphTensor object
