pytorch 在conda下载并离线安装

1、安装anconda

2、添加清华镜像

conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch

3、在线安装

conda install pytorch torchvision torchaudio cudatoolkit=11.1

4、出现y/n时,选择y,然后过一会儿中断

5、下载并本地安装

于Anaconda3\pkgs查看urls.txt文件,得到如:

https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/win-64/pytorch-1.8.0-py3.8_cuda10.2_cudnn7_0.tar.bz2

可进行下载

conda安装此包:

conda install –use-local pytorch-1.8.0-py3.8_cuda10.2_cudnn7_0.tar.bz2

conda install –use-local cudatoolkit-10.2.89-hb195166_8.tar.bz2

此步会自动将包拷入到pkgs目录下并解压

到指定的conda 激活环境下,再执行:

conda install -c local pytorch cudatoolkit=10.2

即可,如果需要其它包,则对应一一下载
