Pytorch environment installation
Pytorch official website
Choose the version you want to use.
Since the direct installation of pytorch in China will be slow and error-prone, the installation speed of Tsinghua mirror is generally much faster. The detailed steps are directly quoted from here: https://mirror.tuna.tsinghua.edu.cn/help/anaconda/
Tsinghua's Pytorch mirror is strongly recommended! ! !
One, modify the .condarc file
Find the .condarc file in the "C:\Users\Username" directory, and copy the following content to this file. If you don't have this file, you can execute conda config --set show_channel_urls yes to generate the file and then modify it.
channels:
- defaults
show_channel_urls: true

Second, execute the installation command
Find the installation command of the corresponding version from the pytorch official website. Here I installed pytorch1.7, windows 10, cuda 10.1, python version, execute the following command in Anaconda power shell:
conda install pytorch torchvision torchaudio cudatoolkit=10.1 -c pytorch
Install it in a few minutes!
If you have previously installed it, you may get an error, possibly because of the files left over from the previous installation failure. You can delete the corresponding file or folder under C:\Users\Administrator\anaconda3\pkgs as prompted, and then execute the installation command again.
