Function Usage

Sets the original format after a tensor description is created by the aclCreateTensorDesc call.

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 data access efficiency on the AI processor. Along the process, the operator shape is also inferred to facilitate internal computation.
