torch.deg2rad
torch.deg2rad(input, *, out=None) -> Tensor
Returns a new tensor with each of the elements of "input" converted
   from angles in degrees to radians.
Parameters:
      input (Tensor) -- the input tensor.
Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> a = torch.tensor([[180.0, -180.0], [360.0, -360.0], [90.0, -90.0]])
  >>> torch.deg2rad(a)
  tensor([[ 3.1416, -3.1416],
          [ 6.2832, -6.2832],
          [ 1.5708, -1.5708]])
