    //! For strongly typed networks, this method should be used only for network inputs,

    //! For weakly typed networks, this method can be used for network outputs too, but

    //! or `INetworkDefinition::markOutputForShapes`).

    //! However, marking it first has two advantages:
    //!
    //!     * It avoids warnings that the tensor is not yet a network I/O tensor.

    //! \brief Whether the tensor is a shape tensor.
    //!
    //! A shape tensor is a tensor that is related to shape calculations.
    //! It must have type Int32, Int64, Bool, or Float, and its shape must be determinable at build time.
    //! Furthermore, it must be needed as a shape tensor, either marked as a network shape
    //! output via markOutputForShapes(), or as a layer input that is required to be a shape
    //! tensor, such as the second input to IShuffleLayer. Some layers are "polymorphic" in
    //! this respect. For example, the inputs to IElementWiseLayer must be shape tensors
    //! if the output is a shape tensor.
    //!
    //! The TensorRT Developer Guide gives the formal rules for what tensors are shape tensors.
    //!
    //! The result of isShapeTensor() is reliable only when network construction is complete.
    //! For example, if a partially built network sums two tensors T1 and T2 to create
    //! tensor T3, and none are yet needed as shape tensors, isShapeTensor() returns false
    //! for all three tensors.  Setting the second input of IShuffleLayer to be T3 would
    //! cause all three tensors to be shape tensors, because IShuffleLayer requires that its
    //! second optional input be a shape tensor, and IElementWiseLayer is "polymorphic".
    //!
    //! It is possible for a tensor to be both a shape tensor and an execution tensor.
    //!

    //!
    //! The result of isExecutionTensor() is reliable only when network construction is complete.
    //! For example, if a partially built network has no path from a tensor to a network output,
    //! isExecutionTensor() returns false. Completing the path would cause it to become true.
    //!
    //!
    //! A tensor with isShapeTensor() == false and isExecutionTensor() == false
    //! can still show up as an input to the engine if its dimensions are required.

//!         The operation can be formulated as output[i_1, ..., i_{q-1}] = data[indices[i_1, ..., i_{q-1}]]
//!

//! For a strongly typed network, the layer is an identity function, i.e. the output

//! 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.

//!
//! \brief A resize layer in a network definition.
//!
//! Resize layer can be used for resizing a N-D tensor.
//!
//! Resize layer currently supports the following configurations:
//!     -   InterpolationMode::kNEAREST - resizes last `m` dimensions of N-D, where 0 < m <= min(8, N) and N > 0
//!     -   InterpolationMode::kLINEAR - resizes last `m` dimensions of N-D, where 0 < m <= min(3, N) and N > 0
//!
//! Default resize mode is InterpolationMode::kNEAREST.
//!
//! The coordinates in the output tensor are mapped to coordinates in the input tensor using a function set by calling
//! setCoordinateTransformation(). The default for all InterpolationMode settings (nearest, linear, bilinear, etc.) is
//! ResizeCoordinateTransformation::kASYMMETRIC.
//!
//! The resize layer provides two ways to resize tensor dimensions.
//!     -   Set output dimensions directly. It can be done for static as well as dynamic resize layer.
//!         Static resize layer requires output dimensions to be known at build-time.
//!         Dynamic resize layer requires output dimensions to be set as one of the input tensors.
//!     -   Set scales for resize. Each output dimension is calculated as floor(input dimension * scale).
//!         Only static resize layer allows setting scales where the scales are known at build-time.
//!
//! If executing this layer on DLA, the following combinations of parameters are supported:
//!
//! - In kNEAREST mode:
//!     * (ResizeCoordinateTransformation::kASYMMETRIC, ResizeSelector::kFORMULA, ResizeRoundMode::kFLOOR)
//!     * (ResizeCoordinateTransformation::kHALF_PIXEL, ResizeSelector::kFORMULA, ResizeRoundMode::kHALF_DOWN)
//!     * (ResizeCoordinateTransformation::kHALF_PIXEL, ResizeSelector::kFORMULA, ResizeRoundMode::kHALF_UP)
//!
//! - In kLINEAR mode:

//!     * (ResizeCoordinateTransformation::kHALF_PIXEL, ResizeSelector::kUPPER)

//! \class IQuantizeLayer
//!
//! \brief A Quantize layer in a network definition.
//!
//! This layer accepts a floating-point data input tensor, and uses the scale and zeroPt inputs to
//! quantize the data according to:
//! \p output = clamp(round(\p input / \p scale) + \p zeroPt)
//!
//! Rounding type is rounding-to-nearest ties-to-even (https://en.wikipedia.org/wiki/Rounding#Round_half_to_even).
//! Clamping range according to data type:
//! - FP8: [-448, 448]
//! - INT4: [-8, 7]
//! - INT8: [-128, 127]
//!
//! The first input (index 0) is the tensor to be quantized.
//! The second (index 1) and third (index 2) are the scale and zero point respectively.
//! \p scale and \p zeroPt should have identical dimensions, and rank lower or equal to 2.
//!
//! The \p zeroPt tensor is optional, and if not set, will be assumed to be zero. Its data type must match the
//! output data type. \p zeroPt must only contain zero-valued coefficients, because only symmetric quantization is
//! supported.
//! The \p scale value must be a scalar for per-tensor quantization, a 1D tensor for per-channel quantization, or the
//! same rank as the input tensor for block quantization. All \p scale coefficients must have strictly positive values.
//! The size of the 1D \p scale tensor must match the size of the quantization axis. For block quantization, the shape
//! of \p scale tensor must match the shape of the input, except for the blocking dimension (the last or second to last
//! dimension). The size of \p zeroPt must match the size of \p scale.
//!
//! The subgraph which terminates with the \p zeroPt tensor must be a build-time constant containing only zeros.
//! The output type, if constrained, must be constrained to DataType::kINT8, DataType::kFP8, DataType::kINT4 or
//! DataType::kFP4. The input type, if constrained, must be constrained to DataType::kFLOAT, DataType::kHALF, or
//! DataType::kBF16. The output size is the same as the input size. The quantization axis is in reference to the input
//! tensor's dimensions.
//!
//! IQuantizeLayer supports DataType::kFLOAT, DataType::kHALF, or DataType::kBF16 precision and will default to
//! DataType::kFLOAT precision during instantiation. For strongly typed networks, if the scale data type is
//! DataType::kHALF or DataType::kBF16, it must match the input data type. For MXFP8 quantization, the \p scale
//! data type must be DataType::kE8M0.
//!
//! IQuantizeLayer supports DataType::kINT8, DataType::kFP8, DataType::kINT4 or DataType::kFP4 output.
//!
//! As an example of the operation of this layer, imagine a 4D NCHW activation input which can be quantized using a
//! single scale coefficient (referred to as per-tensor quantization):
//!     For each n in N:
//!         For each c in C:
//!             For each h in H:
//!                 For each w in W:
//!                     output[n,c,h,w] = clamp(round(\p input[n,c,h,w] / \p scale) + \p zeroPt)
//!
//! Per-channel quantization is supported only for weight inputs. Thus, Activations cannot be quantized per-channel.
//! As an example of per-channel operation, imagine a 4D KCRS weights input and K (dimension 0) as the quantization
//! axis. The scale is an array of coefficients, and must have the same size as the quantization axis.
//!     For each k in K:
//!         For each c in C:
//!             For each r in R:
//!                 For each s in S:
//!                     output[k,c,r,s] = clamp(round(\p input[k,c,r,s] / \p scale[k]) + \p zeroPt[k])
//!
//! Block quantization is supported for input types DataType::kFP4, DataType::kFP8 and DataType::kINT4.
//! As an example of blocked operation, imagine a 2D RS input with R (dimension 0) as the blocking axis and B as the
//! block size. The scale is a 2D array of coefficients, with dimensions (R//B, S).
//!     For each r in R:
//!         For each s in S:
//!             output[r,s] = clamp(round(\p input[r,s] / \p scale[r//B, s]) + \p zeroPt[r//B, s])
//!
//! \note Only symmetric quantization is supported.
//! \note Currently the only allowed build-time constant \p zeroPt subgraphs are:
//! 1. Constant -> Quantize
//! 2. Constant -> Cast -> Quantize
//!
//! \note The input tensor for this layer must not be a scalar.
//!
//! \warning Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

//!       ScatterMode::kELEMENT: q must be the same as r
//! * Updates is a tensor of rank s >= 1 that provides the data

//!   Constraints on the rank of Updates depend on the mode:
//!       ScatterMode::kND: s = r + q - shape(Indices)[-1] - 1
//!       Scattermode::kELEMENT: s = q = r
//! * Output is a tensor with the same dimensions as Data that stores the resulting values of the

//!
//!     Given that data dims are {d_0,...,d_{r-1}} and indices dims are {i_0,...,i_{q-1}},
//!     define k = indices[q-1], it follows that updates dims are {i_0,...,i_{q-2},d_k,...,d_{r-1}}
//!     The updating can be computed by:
//!         foreach slice in indices[i_0,...,i_{q-2}]
//!             output[indices[slice]] = updates[slice]
//!
//! ScatterMode::kELEMENT

//!         Let K = sequence J with element [axis] replaced by X
//!         output[K] = updates[J]
//!
//!     For example, if indices has dimensions [N,C,H,W] and axis is 2, then the updates happen as:
//!
//!         for n in [0,n)
//!             for c in [0,n)

//! intersection-over-union (IoU) with previously selected boxes is less than or equal to a given threshold.
//! This layer implements NMS per batch item and per class.
//!
//! Per batch item, boxes are initially sorted by their scores without regard to class. Only boxes up to a maximum of
//! the TopK limit are considered for selection (per batch). During selection, only overlapping boxes of the same class
//! are compared, so that overlapping boxes of different classes do not suppress each other.
//!
//! For each batch item, the ordering of candidate bounding boxes with the same score is unspecified, but the ordering
//! will be consistent across different runs for the same inputs.
//!
//! The layer has the following inputs, in order of input index:
//!
//! * Boxes contains the input bounding boxes. It is a linear tensor of type kFLOAT or kHALF. It has
//!   shape [batchSize, numInputBoundingBoxes, numClasses, 4] if the boxes are per class, or
//!   [batchSize, numInputBoundingBoxes, 4] if the same boxes are to be used for each class.
//! * Scores contains the per-box scores. It is a linear tensor of the same type as Boxes. It has shape
//!   [batchSize, numInputBoundingBoxes, numClasses].
//! * MaxOutputBoxesPerClass is the maximum number of output boxes per batch item per class.
//!   It is a scalar (0D tensor) of type kINT32.
//! * IoUThreshold is the maximum IoU for selected boxes. It is a scalar (0D tensor) of type kFLOAT in the range
//!   [0.0f, 1.0f]. It is an optional input with default 0.0f.
//! * ScoreThreshold is the value that a box score must exceed in order to be selected. It is a scalar (0D tensor) of
//! type kFLOAT. It is an optional
//!   input with default 0.0f.
//!
//! The layer has the following outputs, in order of output index:
//!
//! * SelectedIndices contains the indices of the selected boxes. It is a linear tensor of type kINT32 or kINT64. It has
//! shape
//!   [NumOutputBoxes, 3]. Each row contains a (batchIndex, classIndex, boxIndex) tuple.
//!   The output boxes are sorted in order of increasing batchIndex and then in order of decreasing score within each
//!   batchIndex. For each batchIndex, the ordering of output boxes with the same score is unspecified. If
//!   MaxOutputBoxesPerClass is a constant input, the maximum number of output boxes is batchSize * numClasses *
//!   min(numInputBoundingBoxes, MaxOutputBoxesPerClass). Otherwise, the maximum number of output boxes is batchSize *
//!   numClasses * numInputBoundingBoxes. The maximum number of output boxes is used to determine the upper-bound on
//!   allocated memory for this output tensor.
//! * NumOutputBoxes is the number of output boxes in SelectedIndices. It is a scalar (0D tensor) of type kINT32.
//!
//! \warning There is a hardware-dependent limit K such that only the K highest scoring boxes in each batch item

//!
//! The operation has forward vs. reverse variants, and inclusive vs. exclusive variants.

//!
//! \brief Layer that represents a KVCacheUpdate operation.
//!
//! The KVCacheUpdate layer is used to cache the key or value tensors for the attention mechanism.
//! K and V use separate KVCacheUpdate layers.
//!
//! An IKVCacheUpdateLayer has three inputs (`cache`, `update`, `writeIndices`) and one output.
//! In `kLINEAR` mode, for each batch element i, the layer copies the update tensor into the cache starting at
//! position `writeIndices[i]`. Assuming no out-of-bounds writes occur, the operation for each sequence position
//! s in [0, sequenceLength) is:
//! \code
//! output[i, :, writeIndices[i] + s, :] = update[i, :, s, :]
//! \endcode
//!
//! The output performs in-place updates on the cache tensor, so they must share the same device memory address.
//!
//! \warning Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
