    //! \brief Declare a size tensor at the given output index, with the specified auto-tuning formula and upper bound.

    //! A size tensor allows a plugin to have output dimensions that cannot be computed solely from input dimensions.
    //! For example, suppose a plugin implements the equivalent of INonZeroLayer for 2D input. The plugin can
    //! have one output for the indices of non-zero elements, and a second output containing the number of non-zero
    //! elements. Suppose the input has size [M,N] and has K non-zero elements. The plugin can write K to the second

    //! IExprBuilder::declareSizeTensor(1,...) to create the IDimensionExpr that respectively denote 2 and K.
    //!
    //! TensorRT also needs to know the value of K to use for auto-tuning and an upper bound on K so that it can
    //! allocate memory for the output tensor. In the example, supposed typically half of the plugin's input elements
    //! are non-zero, and all the elements might be nonzero. then using M*N/2 might be a good expression for the opt

    //! Using this numbering, pos is an index into InOut, where 0 <= pos < nbInputs+nbOutputs.
    //!
    //! TensorRT invokes this method to ask if the input/output indexed by pos supports the format/datatype specified

//!
//! Many of the formats are **vector-major** or **vector-minor**. These formats specify
//! a <em>vector dimension</em> and <em>scalars per vector</em>.
//! For example, suppose that the tensor has has dimensions [M,N,C,H,W],
//! the vector dimension is C and there are V scalars per vector.
//!
//! * A **vector-major** format splits the vectorized dimension into two axes in the
//!   memory layout. The vectorized dimension is replaced by an axis of length ceil(C/V)
//!   and a new dimension of length V is appended. For the example tensor, the memory layout
//!   is equivalent to an array with dimensions [M][N][ceil(C/V)][H][W][V].
//!   Tensor coordinate (m,n,c,h,w) maps to array location [m][n][c/V][h][w][c\%V].
//!
//! * A **vector-minor** format moves the vectorized dimension to become the last axis
//!   in the memory layout. For the example tensor, the memory layout is equivalent to an
//!   array with dimensions [M][N][H][W][ceil(C/V)*V]. Tensor coordinate (m,n,c,h,w) maps
//!   array location subscript [m][n][h][w][c].
//!
//! In interfaces that refer to "components per element", that's the value of V above.
