class cv::cann::AscendStream	In AscendCL Stream(AscendStream) is a task queue. Stream is used to manage the parallelism of tasks. The tasks inside a Stream are executed sequentially, that is, the Stream executes sequentially according to the sent tasks; the tasks in different Streams are executed in parallel. View details

wrapStream()

AscendStream cv::cann::wrapStream(size_t AscendStreamAddress)

#include <opencv2/cann.hpp>

Bindings overload to create a Stream object from the address stored in an existing CANN Runtime API stream pointer (aclrtStream).

Note

Overload for generation of bindings only, not exported or intended for use internally fro C++.
