inlinenoexcept

Get the multi-dimension stride of the deconvolution.

See also: setStrideNd()

◆ setBiasWeights()

void nvinfer1::IDeconvolutionLayer::setBiasWeights ( Weights weights )

inlinenoexcept

Set the bias weights for the deconvolution.

Bias is optional. To omit bias, set the count value of the weights structure to zero.

The bias is applied per-feature-map, so the number of weights (if non-zero) must be equal to the number of output feature maps.

See also: getBiasWeights()

◆ setDilationNd()

void nvinfer1::IDeconvolutionLayer::setDilationNd ( Dims const & dilation )

inlinenoexcept

Set the multi-dimension dilation of the deconvolution.

◆ setInput()

void nvinfer1::ILayer::setInput	(	int32_t	index,
		ITensor &	tensor
	)

inlinenoexcept

Append or replace an input of this layer with a specific tensor.

Parameters

index	the index of the input to modify.
tensor	the new input tensor

Input 0 is the input activation tensor. Input 1 is the kernel tensor. If used, the kernel weights parameter must be set to empty weights. Input 2 is the bias tensor. If used, the bias parameter must be set to empty weights.

See also: getKernelWeights(), setKernelWeights(), getBiasWeights(), setBiasWeights()

◆ setKernelSizeNd()

void nvinfer1::IDeconvolutionLayer::setKernelSizeNd ( Dims const & kernelSize )

inlinenoexcept

Set the multi-dimension kernel size of the deconvolution.

If executing this layer on DLA, there are ttwo restrictions: 1) Only 2D Kernel is supported. 2) Kernel height and width must be in the range [1,32] or the combinations of [64, 96, 128] in one dimension and 1 in the other dimensions, i.e. [1x64] or [64x1] are valid, but not [64x64].

See also: getKernelSizeNd()

◆ setKernelWeights()

void nvinfer1::IDeconvolutionLayer::setKernelWeights ( Weights weights )

inlinenoexcept

Set the kernel weights for the deconvolution.

The weights are specified as a contiguous array in CKRS order, where C the number of input channels, K the number of output feature maps, and R and S are the height and width of the filter.

See also: getWeights()

◆ setNbGroups()

void nvinfer1::IDeconvolutionLayer::setNbGroups ( int64_t nbGroups )

inlinenoexcept

Set the number of groups for a deconvolution.

The input tensor channels are divided into nbGroups groups, and a deconvolution is executed for each group, using a filter per group. The results of the group convolutions are concatenated to form the output.

If executing this layer on DLA, nbGroups must be one

Note: When using groups in int8 mode, the size of the groups (i.e. the channel count divided by the group count) must be a multiple of 4 for both input and output.

Default: 1

◆ setPaddingMode()

void nvinfer1::IDeconvolutionLayer::setPaddingMode ( PaddingMode paddingMode )

inlinenoexcept

Set the padding mode.

Padding mode takes precedence if both setPaddingMode and setPre/PostPadding are used.

Default: kEXPLICIT_ROUND_DOWN

See also: getPaddingMode()

◆ setPaddingNd()

void nvinfer1::IDeconvolutionLayer::setPaddingNd ( Dims const & padding )

inlinenoexcept

Set the multi-dimension padding of the deconvolution.

The output will be trimmed by this number of elements on both sides of every dimension. In other words, it resembles the inverse of a convolution layer with this padding size. Padding is symmetric, and negative padding is not supported.

Default: (0, 0, ..., 0)

If executing this layer on DLA, padding must be 0.

Default: (0, 0, ..., 0)

If executing this layer on DLA, padding must be 0.

See also: getPostPadding()

◆ setPrePadding()

void nvinfer1::IDeconvolutionLayer::setPrePadding ( Dims const & padding )

inlinenoexcept

Set the multi-dimension pre-padding of the deconvolution.

The output will be trimmed by this number of elements on the start of every dimension. In other words, it resembles the inverse of a convolution layer with this padding size. Negative padding is not supported.

Default: (0, 0, ..., 0)

If executing this layer on DLA, padding must be 0.

Set the multi-dimension stride of the deconvolution.

Default: (1, 1, ..., 1)

If executing this layer on DLA, there are two restrictions: 1) Only 2D Stride is supported. 2) Stride height and width must be in the range [1,32] or the combinations of [64, 96, 128] in one dimension and 1 in the other dimensions, i.e. [1x64] or [64x1] are valid, but not [64x64].
