aclSetTensorOriginFormat
Description
Sets the original format of the tensor after creating the tensor description by calling aclCreateTensorDesc. .
For example, if the original operator shape is 4D with format NHWC or 5D with format NDHWC, the format is automatically converted to NC1HWC0 or NDC1HWC0 during model conversion or online network build to facilitate memory access efficiency on Ascend AI Processor. Along the process, the operator shape is also inferred to facilitate internal computation.
