9.16. Output

Declares that an operator requires a mounted volume or shared memory to write data to. Clara Deploy SDK will ensure that any declared output property values will be available to the executing container application, at the specified path or shaped memory location.

9.16.1.1. name

type: string

Unique name of the output.

Optional in pipeline api-version 0.4.0 and below when an operator only defines a single output; otherwise required.

Mandatory in pipeline api-version 0.5.0 or better for both shared memory items or disk-based output.

When another operator maps an operator’s output, it does so by declaring an input’s from field to match the name of the upstream operator, and its name field to match the name of the desired output.

See names for additional information about names in Clara Deploy SDK pipeline definitions.

9.16.1.2. path

type: string

Container-local path to which Clara Deploy SDK will provide the requested output volume.

The path property must be declared as part of any output declaration in pipeline api-version 0.4.0 and below, or when type (next section) is stream in pipeline api-version 0.5.0 and above. Paths must be fully-qualified.

9.16.1.3. type

(available api-version 0.5.0 and above)

type: string

Describes the Clara structure or Clara primitive.

Clara Primitive Logical Interpretation array Representation
u8, uint8 8-bit unsigned integer array<uint8>[1]
u16, uint16 16-bit unsigned integer array<uint16>[1]
u32, uint32 32-bit unsigned integer array<uint32>[1]
u64, uint64 64-bit unsigned integer array<uint64>[1]
i8, int8 8-bit unsigned integer array<int8>[1]
i16, int16 16-bit signed integer array<int16>[1]
i32, int32 32-bit signed integer array<int32>[1]
i64, int64 64-bit signed integer array<int64>[1]
f16, float16 16-bit floating-point array<float16>[1]
f32, float32 32-bit floating-point array<float32>[1]
f64, float64 64-bit floating-point array<float64>[1]

9.16.1.4. element-type

(available api-version 0.5.0 and above)

type: string

Must be specified only for array and stream types (see table above); must be omitted for Clara primitives and string.

element-type accepts only Clara primitive types (see Table under type section).

9.16.1.5. shape

(available api-version 0.5.0 and above)

type: list of dimension lengths. Use -1 to indicate that the length is dynamic (will be set at run-time). Fixed (not dynamic) lengths must be greater than zero.

Must be specified only for array type. Omitted for all other types.

Accepts a list of dimension lengths. Use -1 to indicate the size is dynamic (will be defined at run-time). Fixed (not dynamic) dimension lengths must be greater than zero.

9.16.1.6. Examples:

3D array with dynamic first dimension.
