depthwiseConvolution3D(_:weights:descriptor:name:)

Creates a 3D depthwise convolution operation and returns the result tensor.

Declaration

func depthwiseConvolution3D(_ source: MPSGraphTensor, weights: MPSGraphTensor, descriptor: MPSGraphDepthwiseConvolution3DOpDescriptor, name: String?) -> MPSGraphTensor

Parameters

  • source:

    A 3D Image source as tensor - must be at least rank=4 (CDHW when channelDimensionIndex = -4).

  • weights:

    The weights tensor, must be rank=4 - axes are interpreted as CDHW when channelDimensionIndex = -4 .

  • descriptor:

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

  • name:

    The name for the operation.

Return Value

A valid MPSGraphTensor object

Discussion

Works exactly like depthwise convolution2D, but in three dimensions. Supports different layouts with the channelDimensionIndex property. If your weights need a different layout add a permute operation on them before this operation.
