             aclError aclrtAllocatorUnregister(aclrtStream stream)

Python Function

        
             ret = acl.rt.allocator_unregister(stream)

Parameter	Description
stream	Int, stream corresponding to the Allocator.

Return Value	Description

The Atlas 200/500 A2 Inference Product does not support this API.
Before destroying an Allocator, call this API to deregister the Allocator.
If the stream to be deregistered does not exist or this API is called for multiple times to deregister the stream, no operation will be performed and a success message is returned.
