Detailed Description
A layer that represents the identity function.
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, is recognized as incorrect as of TensorRT 8.4, but is retained for API compatibility within TensorRT 8.x releases. In a future major release the behavior will change to record an error if the network output tensor type is incompatible with the layer output type. E.g., implicit conversion from kFLOAT to kINT32 will not be allowed, and instead such a conversion will require calling setOutputType(DataType::kINT32).
- Warning
- Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
