ValueDepend

Function Usage

Indicates whether an input is a data-dependent input. Functions such as Tiling and InferShape depend on specific data of such inputs when implemented. The input data is on the host. You can obtain the input data by using GetInputTensor of the TilingContext class or GetInputTensor of the InferShapeContext class in the Tiling or InferShape function.

OpParamDef &ValueDepend(Option value_depend, DependScope scope)

Parameters

Parameter	Input/Output	Description
value_depend	Input	The options of value_depend are as follows: REQUIRED: The operator input must be of the Const type. The operator input type (Const) is verified by using the call to SetCheckSupport. If the verification is passed, the input value is fed to the operator. Otherwise, an error is reported. OPTIONAL: The operator input is not necessarily of the Const type. However, the input value is fed to the operator only when it is of the Const type.
scope	Input	The scope type is the enumeration DependScope. The options are as follows: ALL: The implementation of functions such as Tiling and InferShape depends on the input data. The behavior is the same as that of calling the ValueDepend overloading API of a single parameter. TILING: Refers to the tensor value during tiling. Tiling offload is supported.

Parameter

Input/Output

Description

value_depend

Input

The options of value_depend are as follows:

REQUIRED: The operator input must be of the Const type.
The operator input type (Const) is verified by using the call to SetCheckSupport. If the verification is passed, the input value is fed to the operator. Otherwise, an error is reported.
OPTIONAL: The operator input is not necessarily of the Const type. However, the input value is fed to the operator only when it is of the Const type.

scope

Input

The scope type is the enumeration DependScope. The options are as follows:

ALL: The implementation of functions such as Tiling and InferShape depends on the input data. The behavior is the same as that of calling the ValueDepend overloading API of a single parameter.
TILING: Refers to the tensor value during tiling. Tiling offload is supported.

Returns

Restrictions

Only operator inputs can be configured. The input parameter data type can be set to DT_FLOAT, DT_BOOL, DT_INT64, DT_UINT64, DT_INT32, DT_UINT32, DT_INT16, DT_UINT16, DT_INT8, or DT_UINT8, and one of the following conditions must be met:

1. If the input parameter data type is set to DT_FLOAT, the generated output type is aclFloatArray (aclnn data type).

2. If the input parameter data type is set to DT_BOOL, the generated output type is aclBoolArray (aclnn data type).

3. If the input parameter data type is set to DT_INT64, DT_UINT64, DT_INT32, DT_UINT32, DT_INT16, DT_UINT16, DT_INT8, or DT_UINT8, the generated output type is aclIntArray (aclnn data type). If the data type configuration contains a data type other than DT_INT64, an additional set of input/output data type combinations corresponding to DT_INT64 must be added.
