Description
Outputs the tensor slice information.
Application scenario: The OutfeedEnqueueOpV2 operator requires the allocation of a large block of memory on the device to store data. If the device memory is insufficient, memory allocation may fail and cause some operators to fail to execute normally. In this case, you can call this API to obtain tensor slice information (slice count and slice index), and then splice the operator tensor data based on the slice information.

Parameters
Parameter |
Input/Output |
Description |
|---|---|---|
dataItem |
Input |
Pointer to data of the acltdtDataItem type. acltdtDataItem is used to identify a tensor of a service. Call acltdtCreateDataItem to create data of the acltdtDataItem type in advance. |
sliceNum |
Output |
Number of slices of a single tensor. |
sliceId |
Output |
Data slice index of the sliced tensor. |
Returns
0 on success; else, failure. For details, see aclError.
