mac uses conda (anaconda is the same as miniconda) to install the new version of torch

Downloading from the command line given by pytorch will be very slow, so we should modify the mirror source and then download torch

1. Add mirror image

Enter the following command in the terminal to add a mirror:

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.bfsu.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.bfsu.edu.cn/anaconda/pkgs/main/
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/bioconda/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/menpo/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/fastai/

2. Open the pytorch official website

Find the official conda download command:

But it must be removed -c pytorch, and the corresponding package will be downloaded from the mirror source (Tsinghua source, Ali source) added by itself by default during installation, so use the command line here:

conda install pytorch::pytorch torchvision torchaudio

Here you can specify the version number, for example:torch==2.0.1

3. Check whether the terminal download is using the mirror source

4. You can .condarcremove the default channel in
