Thanks, I only want to get the Scalar, not Scalar to tensor. So basically just do this?

```
auto base = c10::Scalar(c10::complex<double>(1.0, 2.0));
```

Is this equivilent to the python code of:

```
base = 1.0 + 2.0j;
```

Since the default dtype for scalar is double not float.

Another question is that, when I try to print out the complex tensor using the `std::cout`

method, the imaginary part didn’t get printed out.

Here is a simple example:

```
auto a = at::tensor({c10::complex<double>(1, 0.5), c10::complex<double>(1, 0.5)}, at::dtype(at::kComplexFloat));
std::cout << a << std::endl;
```

What I got:

```
[W Copy.cpp:219] Warning: Casting complex values to real discards the imaginary part (function operator())
1
1
```

So, how can I print out the value of a complex tensor including the imaginary part?

Much appreciated.
