Hi,
I’m using Pytorch 1.5.1.
I’m having a problem using some functions that exist is the documentation, but I got the error  'torch' has no attribute.
For example, the code provided in this pytorch link 1 doesn’t work:
>>> import torch
>>> x=torch.randn(4, 2)
>>> torch.view_as_complex(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'torch' has no attribute 'view_as_complex'
>>> 

How can I solve this problem?
Thank you in advance!
