Hi,
Actually the work is in progress but there are some work arounds by third party libraries as you can find in this post:

  
    
    
    Pytorch with complex tensors 
  
  
    Hi, 
You can check this issue to see the internal work on complex tensors: https://github.com/pytorch/pytorch/issues/755 
Also third party libraries might give some partial support for complex tensors. A quick search points to https://github.com/williamFalcon/pytorch-complex-tensor for example.
