#### 调用示例

```
import torch
import torch_atb  

def elewise_add():
    input1_npu = torch.randn(2, 3, dtype=torch.float16).npu()
    input2_npu = torch.randn(2, 3, dtype=torch.float16).npu()
    print("input1: ", input1_npu)
    print("input2: ", input2_npu)
    elewise_param = torch_atb.ElewiseParam(elewise_type = torch_atb.ElewiseParam.ElewiseType.ELEWISE_ADD)
    elewise = torch_atb.Operation(elewise_param)

    def elewise_run():
        elewise_outputs = elewise.forward([input1_npu, input2_npu])
        return elewise_outputs

    outputs = elewise_run()
    print("outputs: ", outputs)
