NVIDIA : Install CUDA 11.72022/08/10
 
Install GPU Computing Platform (GPGPU (General-Purpose computing on Graphics Processing Units)), CUDA (Compute Unified Device Architecture) provided by NVIDIA.
To use CUDA, it needs your computer has NVIDIA Graphic cards and also they are the CUDA-Enabled products.
Make sure the details on the site below. (most products are ready in the past few years)
⇒ https://developer.nvidia.com/cuda-gpus
[1]
Install NVIDIA Graphic Driver for your Graphic Card, refer to here.
[2] Install CUDA from the NVIDIA official repository.
It based on the environment you set NVIDIA official repository when installing driver on the previous [1] section.
