如何在Ubuntu上简单安装pytorch-GPU

1.Conda创建虚拟环境

conda create -n pytorch_gpu python=3.6

2.安装pytorch

2.1 Conda安装pytorch(下载安装慢,网络条件不好,下载依赖包经常中断)

conda install pytorch torchvision torchaudio cudatoolkit=11.0 

2.2 Pip安装pytorch(下载安装相对较快,推荐)

 pip install torch==1.7.1+cu110 torchvision==0.8.2+cu110 torchaudio===0.7.2 -f https://download.pytorch.org/whl/torch_stable.html

3.测试pytorch安装成功

(pytorch_gpu) scnu-go@scnu-go:~$ python
