-0.9955 ** 0.0448

torch.Tensor([-0.9955]) ** torch.Tensor([0.0448])
Out[16]: tensor([nan])

I want to use `pytorch`

get the number `-0.9997979654463205`

. Thanks.

The plain Python code calculates:

```
-(0.9955 ** 0.0448)
> -0.9997979654463205
```

While you are trying to calculate

```
(-0.9955) ** 0.0448
> (0.989911956308302+0.14025081271947198j)
```

in PyTorch, which is a complex number.

If you want the first output in PyTorch, just use:

```
-1.0 * torch.tensor([0.9955]) ** torch.tensor([0.0448])
> tensor([-0.9998])
```

Oh, thanks.

It’s my problem that I didn’t notice the priorities of `-`

and `**`

when writing the demo, but your second demo is really what I’m trying to say, thank you very much!

If I write demo correctly, I guess I would understand the problem.
