depthwiseConvolution2DWeightsGradient(_:source:outputShape:descriptor:name:)
Creates a 2D-depthwise convolution gradient for weights operation and returns the result tensor.
Declaration
func depthwiseConvolution2DWeightsGradient(_ incomingGradient: MPSGraphTensor, source: MPSGraphTensor, outputShape: [NSNumber], descriptor: MPSGraphDepthwiseConvolution2DOpDescriptor, name: String?) -> MPSGraphTensorParameters
- incomingGradient:
A 2D input gradient tensor - must be of rank=4. The layout is defined by
descriptor.dataLayout. - source:
A 2D Image source as tensor - must be of rank=4. The layout is defined by
descriptor.dataLayout. - outputShape:
The shape of the οutput tensor (and therefore weight 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
