Properties

Name	Type	Description
`arity`readonly	`readonly [number, number]`	How many inputs it takes, fewest and most.
`ranks`readonlyoptional	`readonly number[]`	The rank each input must have, in order, where it matters. Checked before `shape` runs, because an operator reading an image as `[channels, height, width]` reads a value with one more axis as its first three and validates it — and then declares an output it fills only part of.

shape(inputs: readonly Shape[], attributes: Attributes): number[] | string

Parameter	Type	Description
`inputs`	`readonly Shape[]`
`attributes`	`Attributes`

Scratch values it needs beyond its output, if any.

Parameter	Type	Description
`inputs`	`readonly Shape[]`
`attributes`	`Attributes`

evaluate(inputs: readonly Float32Array[], shapes: readonly Shape[], attributes: Attributes, out: Float32Array, scratch: Float32Array): void
