Expand description

! \class IIdentityLayer ! ! \brief A layer that represents the identity function. ! ! For a strongly typed network, the layer is an identity function, i.e. the output ! tensor elements are identical to the input tensor elements, possibly with a change ! in layout. For example, if a network consists of a single IIdentityLayer, the network ! input and output must have the same type, but the input can have NCHW layout and ! the output can have NHWC layout. ! ! If the network is weakly typed, the layer is additionally permitted some type conversions ! as described below. ! ! If the output type is explicitly specified via setOutputType, IIdentityLayer can be ! used to convert from one type to another. Other than conversions between the same ! type (kFLOAT -> kFLOAT for example), the only valid conversions are: ! ! (kFLOAT | kHALF | kINT32 | kBOOL) -> (kFLOAT | kHALF | kINT32 | kBOOL) ! ! (kFLOAT | kHALF) -> kUINT8 ! ! kUINT8 -> (kFLOAT | kHALF) ! ! Conversion also happens implicitly, without calling setOutputType, if the output ! tensor is a network output. ! ! Two types are compatible if they are identical, or are both in {kFLOAT, kHALF}. ! Implicit conversion between incompatible types, i.e. without using setOutputType, ! was recognized as incorrect as of TensorRT 8.4, but was retained for API compatibility ! within TensorRT 8.x releases. In TensorRT 10.0 onwards it is an error if the network ! output tensor type is incompatible with the layer output type. E.g., implicit conversion ! from kFLOAT to kINT32 is not allowed. ! ! To explicitly convert kFLOAT to kINT32: ! ! * Preferred: use ICastLayer. ! ! * Legacy alternative: use IIdentityLayer and setOutputType(DataType::kINT32). ! ! Similar advice applies for explicit conversion in the other direction. ! ! \warning Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI. !
