Abstract: An operator processing method includes obtaining a real-time shape of any to-be-output first tensor by combining in real time one or more micro-operators in a pre-constructed micro-operator library. Then, a micro-operator included in one combination (for example, a combination with optimal performance because different combinations have different performance) is selected for execution. Micro-operators in the micro-operator library are pre-compiled. Therefore, a compiler is not needed. In addition, shapes of the micro-operators are fixed and different, and are used as a “basis” of “shape space”.
