torch.is_complex

torch.is_complex(input: Tensor) → bool

Returns True if the data type of input is a complex data type i.e., one of torch.complex64, and torch.complex128.

Parameters

input (Tensor) – the input tensor.

Example:

>>> torch.is_complex(torch.tensor([1, 2, 3], dtype=torch.complex64))
True
>>> torch.is_complex(torch.tensor([1, 2, 3], dtype=torch.complex128))
True
>>> torch.is_complex(torch.tensor([1, 2, 3], dtype=torch.int32))
False
>>> torch.is_complex(torch.tensor([1.0, 2.0, 3.0], dtype=torch.float16))
False
