pytorch与cuda环境安装操作

Pytorch

• 安装 11.8 Windows版本的

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

在cmd或者power shell中运行
![需要python环境]

输入检查torch和cuda的命令

C:\Windows\system32>python
Python 3.11.3 (tags/v3.11.3:f3909b8, Apr  4 2023, 23:49:59) [MSC v.1934 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>> torch.cuda.is_available()
True

返回true则表明，cuda和pytorch环境成功安装
