Failed to initialize NVML: Driver/library version mismatch

//檢視顯示卡驅動所使用的核心版本以及編譯的gcc版本
cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  470.74  Mon Sep 13 23:09:15 UTC 2021
GCC version:  gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04) 

檢視當前系統核心(不是升級系統問題，省略此步驟)
當前問題是切換了gcc版本，檢視當前gcc版本
