Function _Rank

express/NeuralNetWorkOp.cpp:1305–1311

Returns the rank of a variable. Returns a 0-D int32 variable representing the rank of input. Note: The rank of a variable is not the same as the rank of a matrix. It's the number of indices required to uniquely select each element of the variable. It's also known as "order", "degree", or "ndims." Args: input: A variable. Returns: A 0-D variable of type Halide_Type_Int */

A 0-D variable of type Halide_Type_Int
