[Open3D ERROR] CUDA is not available

HI,

I get the above error while completing this:

import open3d.core as o3c
import open3d as o3d
import numpy as np
a_cpu = o3c.Tensor([0, 1, 2])
a_gpu = a_cpu.cuda(0)

So, guess cuda is not installed properly or configured properly in Open3d.
However it is working with python torch.

I’m running Ubuntu 20.04. I see that the open3d requires an older version of cuda (10.1?).

However, cuda 10.1 does not have an installation for Ubuntu 20

Is there a solution for this?

Kind regards

Matt
