Hello,
I’m trying to sample from the Student T distribution.
I use the following code:
m = StudentT(torch.tensor([4846]))
m.sample()

That is derived from the docs:
https://pytorch.org/docs/stable/distributions.html 4
Here is the error in and the traceback:
--------------------------------------------------------------------------

      6 annual_investment = torch.tensor([0])
      7 m = StudentT(torch.tensor([4846]))
----> 8 m.sample()
      9 # for x in range(iterations):
