shapedArrayValue

TypeScript

shapedArrayValue(type: "Double" | "Float"): (MLShapedArray<unknown>) | null

Swift declaration

func shapedArrayValue<Scalar>(of type: Scalar.Type) -> MLShapedArray<Scalar>? where Scalar : MLShapedArrayScalar

Returns MLShapedArray of the specified scalar type. The function returns non-nil value when the feature value has MLMultiArray with the specified type. - Parameter type: The scalar type

init · iOS 15.0+

init

TypeScript

static initShapedArray(shapedArray: MLShapedArray<number>): MLFeatureValue

Swift declaration

convenience init<Scalar>(shapedArray: MLShapedArray<Scalar>) where Scalar : MLShapedArrayScalar

Constructs from MLShapedArray. The value will be semantically copied (i.e. Copy-on-Write) to MLFeatureValue object. A mutation to MLFeatureValue won't affect the source MLShapedArray and vise versa. - Parameter shapedArray The MLShapedArray object.

init

TypeScript

static init(value: MLSendableFeatureValue): MLFeatureValue

Swift declaration

convenience init(_ value: MLSendableFeatureValue)

Creates a feature value from a sendable feature value.
