import torch

结果：

导出的程序:
    类 GraphModule(torch.nn.Module):
        def forward(self, arg0_1: "f32[3, 2]"):
                sin: "f32[3, 2]" = torch.ops.aten.sin.default(arg0_1)
            cos: "f32[3, 2]" = torch.ops.aten.cos.default(arg0_1);  arg0_1 = None
            add: "f32[3, 2]" = torch.ops.aten.add.Tensor(sin, cos);  sin = cos = None
            return (add,)
