Function Usage

Obtains the dimension count specified in a tensor description.

Prototype

size_t aclGetTensorDescNumDims(const aclTensorDesc *desc)

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.

Parameter

Input/Output

Description

desc

Input

Pointer to data of the aclTensorDesc type.

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

Returns

Tensor dimension count. If ACL_UNKNOWN_RANK (#define ACL_UNKNOWN_RANK 0xFFFFFFFFFFFFFFFE) is returned, the dimension count is unknown (the shape is dynamic).
