OptionalHasElement - version 15#

This page documents version 15 of operator OptionalHasElement. See OptionalHasElement for the latest version (since version 18).

Domain: ai.onnx
Since version: 15

Returns true if the optional-type input contains an element. If it is an empty optional-type, this op returns false.

Inputs

input (O): The optional input.

Outputs

output (B): A scalar boolean tensor. If true, it indicates that optional-type input contains an element. Otherwise, it is empty.

Type Constraints

O: Constrain input type to optional tensor and optional sequence types. Allowed types: optional(seq(tensor(bool))), optional(seq(tensor(complex128))), optional(seq(tensor(complex64))), optional(seq(tensor(double))), optional(seq(tensor(float))), optional(seq(tensor(float16))), optional(seq(tensor(int16))), optional(seq(tensor(int32))), optional(seq(tensor(int64))), optional(seq(tensor(int8))), optional(seq(tensor(string))), optional(seq(tensor(uint16))), optional(seq(tensor(uint32))), optional(seq(tensor(uint64))), optional(seq(tensor(uint8))), optional(tensor(bool)), optional(tensor(complex128)), optional(tensor(complex64)), optional(tensor(double)), optional(tensor(float)), optional(tensor(float16)), optional(tensor(int16)), optional(tensor(int32)), optional(tensor(int64)), optional(tensor(int8)), optional(tensor(string)), optional(tensor(uint16)), optional(tensor(uint32)), optional(tensor(uint64)), optional(tensor(uint8)).
B: Constrain output to a boolean tensor. Allowed types: tensor(bool).
