torch.real

torch.real(input) → Tensor

Returns a new tensor containing real values of the self tensor. The returned tensor and self share the same underlying storage.

Warning

real() is only supported for tensors with complex dtypes.

Parameters

input (Tensor) – the input tensor.

Example:

>>> x=torch.randn(4, dtype=torch.cfloat)
>>> x
tensor([(0.3100+0.3553j), (-0.5445-0.7896j), (-1.6492-0.0633j), (-0.0638-0.8119j)])
>>> x.real
tensor([ 0.3100, -0.5445, -1.6492, -0.0638])
