Nsight Compute没有权限问题（linux系统上）

遇到的问题：launch之后每个核函数都会出现ERR_NVGPUCTRPERM - The user does not have permission to profile on the target device这个错误
查阅解决方法大家一般都是两点：
1、使用管理员权限运行nsight compute，但这好像是针对windows系统，对linux不太适用；
2、https://developer.nvidia.com/nvidia-development-tools-solutions-err_nvgpuctrperm-permission-issue-performance-counters官网给出了启用该权限的方法，但我按步骤做的时候这一步会出错：modprobe -r nvidia_uvm nvidia_drm nvidia_modeset nvidia-vgpu-vfio nvidia[2] # Unload dependent modules
，不知道要怎么做，请教大家

sudo ncu 也不行吗

sudo ncu 也不行吗

直接输入 ncu-ui 可以打开compute，就是launch时核函数会报没有权限的错误；
sudo ncu-ui 会出现说没有qt平台导致不能start the app【而上边直接ncu-ui软件是可以使用的，这是为什么呢】
命令执行如下：
dell@dell-Precision-5820-Tower-X-Series:~$ ncu-ui
********BP-RCM----nFrame:1, FrameLen=4096, mea=8192, iteration=1  [cudaEvent]***********
dell@dell-Precision-5820-Tower-X-Series:~$ sudo ncu-ui

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

已解决，感谢回答
