Can you check if you have CUDA installed?

nvcc --version

package cu requires the cuda dev toolkit to be installed.

nvcc --version output:

nvcc: NVIDIA (R) Cuda compiler driver

It seems that I havn't do modprobe nvidia_uvm, after this and reboot, this problem is gone 😄

Thanks for the update. I should probably add that into the documentation as well
