Python Function

ret = acl.rt.binary_unload(bin_handle)

Parameter Description

Parameter	Description
bin_handle	Int, handle pointing to the operator binary. This handle is generated when the acl.rt.binary_load API is called.

Return Value Description

Return Value	Description
ret	Int, error code: 0 on success; else, failure.

Restrictions

When this API is called to delete the binary data of an operator, it must be in the same context as the acl.rt.binary_load API. In this way, the binary data of the operator copied to the device through the acl.rt.binary_load API can be deleted at the same time. Otherwise, the binary data of the operator on the device may fail to be deleted.
