Pyro GP: gpmodel.parameters() does not reflect assigned value

Question

Code. X, and y should be irrelevant..

     ker = gp.kernels.RBF(input_dim=2,variance=torch.tensor(1.), lengthscale=torch.ones((2,)))
     gpr = gp.models.GPModel(kernel=ker, X=x, y=y)

• Input:

     list(gpr.parameters())

• Output:

[0]: [Parameter containing:
     tensor(0., requires_grad=True),
     Parameter containing:
     tensor([0., 0.], requires_grad=True)]

The resulting tensors are 0. not 1. expected..
