	Ascend and CANN use stream to implement asynchronous calls. Which means when function returns, operator may not finish, even not start. If caller free any tensors that participate in this operatation, it have a chance to access invalid memory. All tensors should add to holder, holder will be cleaned by waitForCompletion function, or when the stream is destructing.

Ascend and CANN use stream to implement asynchronous calls. Which means when function returns, operator may not finish, even not start. If caller free any tensors that participate in this operatation, it have a chance to access invalid memory.
