使用pip3安装PyTorch与PyG，实现NVIDIA CUDA GPU加速

使用python3的pip3命令安装python依赖库。

# python3 -V
Python 3.12.3
# 
# pip3 -V 
pip 25.0.1 from /root/.pyenv/versions/3.12.3/lib/python3.12/site-packages/pip (python 3.12)

Usage:   pip3 install [options] <package> ...pip3 install [options] -r <requirements file> ... pip3 uninstall [options] <package> ...pip3 uninstall [options] -r <requirements file> ...
