aclGetTensorDescDimV2

Description

Obtains the size of a tensor dimension specified in the tensor description.

Restrictions

If the aclGetTensorDescNumDims call returns ACL_UNKNOWN_RANK, it indicates that the dimension count is unknown. In this case, aclGetTensorDescDimV2 does not output the size of the specified dimension.

Prototype

aclError aclGetTensorDescDimV2(const aclTensorDesc *desc, size_t index, int64_t *dimSize)

Parameters

Parameter

Input/Output

Description

desc

Input

Pointer to data of the aclTensorDesc type.

Call aclCreateTensorDesc to create data of the aclTensorDesc type in advance.

index

Input

Sequence number of the dimension whose size to obtain, indexed starting at 0.

Must be in the range of [0, Dimension count – 1]. Call aclGetTensorDescNumDims to obtain the dimension count.

dimSize

Output

Pointer to the size of the dimension specified by index in the tensor description.

If -1 is returned, the dimension size is not determinable until runtime.

Returns

The value 0 indicates success, and other values indicate failure. For details, see aclError.
