为了简单，我用显卡切换器安装了nvidia驱动，

根据驱动版本对应表安装了cuda11.3，

./nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Mon_May__3_19:15:13_PDT_2021
Cuda compilation tools, release 11.3, V11.3.109
Build cuda_11.3.r11.3/compiler.29920130_0

但是执行 ./deviceQuery是报错

➜  deviceQuery ./deviceQuery 
./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

而且降低cuda版本，也报这个错误，是不是用显卡切换器安装的驱动有问题？请有经验的大佬帮帮忙！
