This is a dreaded error that seems pop up its ugly head again and again, in particular after upgrading CUDA or Tensorflow.
Typcially it looks like this:

Here is a solution that currently seems to work on my system, 
with Cuda 11.0 and Tensorflow 2.4.0, you can try it if all the

        self.slope = nn.Parameter(torch.zeros(1, 1)+slope)
        self.w0 = w0
