Detailed Description

A concatenation layer in a network definition.

The output dimension along the concatenation axis is the sum of the corresponding input dimensions. Every other output dimension is the same as the corresponding dimension of the inputs.

Warning
All tensors must have the same dimensions except along the concatenation axis.
Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

Member Function Documentation

◆ getAxis()

int32_t nvinfer1::IConcatenationLayer::getAxis ( ) const
inlinenoexcept

Get the axis along which concatenation occurs.

setAxis()

◆ setAxis()

void nvinfer1::IConcatenationLayer::setAxis ( int32_t  axis)
inlinenoexcept

Set the axis along which concatenation occurs.

The default axis is the number of tensor dimensions minus three, or zero if the tensor has fewer than three dimensions. For example, for a tensor with dimensions NCHW, it is C. For implicit batch mode, the number of tensor dimensions does NOT include the implicit batch dimension.

When running this layer on the DLA, the concatenation axis must be the third to last axis, e.g. C if tensor dimensions are NCHW.

Parameters
axisThe axis along which concatenation occurs.
