Overview

Function Description

The msopst tool available in CANN Toolkit is used to generate ST cases and test your operators in the hardware environment. It provides the following functions:

Generates an operator test case definition file (.json) based on the operator information library definition file (.ini), as the input of operator ST.
Generates the ST data and test case execution code based on the operator test case definition file, for running the test cases in the hardware environment.
Generates an ST report (st_report.json) that records information about test cases and phase-by-phase execution states.
Constructs a user-defined function for generating expected operator output and displays the comparison result between the expected operator output and the actual output.
