Detailed Description

An Activation layer in a network definition.

This layer applies a per-element activation function to its input.

The output has the same shape as the input.

The input is a shape tensor if the output is a shape tensor.

Warning
Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

◆ setActivationType()

void nvinfer1::IActivationLayer::setActivationType ( ActivationType  type)
inlinenoexcept

Set the type of activation to be performed.

On the DLA, the valid activation types are kRELU, kSIGMOID, kTANH, and kCLIP.

◆ setAlpha()

void nvinfer1::IActivationLayer::setAlpha ( float  alpha)
inlinenoexcept

Set the alpha parameter (must be finite).

This parameter is used by the following activations: LeakyRelu, Elu, Selu, Softplus, Clip, HardSigmoid, ScaledTanh, ThresholdedRelu.

It is ignored by the other activations.
