Nvidia-smi returns segmentation fault with cuda toolkit for arm in ubuntu 18.04

I have installed cuda toolkit of arm in ubuntu 18.04 LTS with tesla t4 card.

But the nvidia-smi returns segmentation fault after the cuda toolkit installed successfully

Hope anyone can help.

I also run into this issue.
nvidia-smi will hang.
./deviceQuery also hang.
I get cuda from https://developer.nvidia.com/cuda-toolkit/arm
My platform is armv8.0 aarch64.
Anybody know this issue?
