Hey guys!

So I am trying to create the following rather simple function:

```
# Make sure to use pytorch version 1.6.0 as I am using type torch.cfloat
from torch import cos, tensor
def func():
return tensor([[1.0, - 1j*cos(tensor(1.0))],[1.0,0.0]], dtype=torch.cfloat)
print(func())
```

I get an error stating that: “RuntimeError: value cannot be converted to type double without overflow: (0,-0.848705)”.

I have played around with different options for a while and it seems like this error is induced by the fact that I am doing 1j*cos(tensor(1.0)). Can someone explain what is going wrong when I multiply this cosine of tensor(1.0) by this complex amplitude?
