MAC下pytorch安装_mac下安装torch-1.13.1-cp37-none-macosx_10_9_x86_64.wh

1、安装环境

• 系统：macOS
• python版本：python3.8.5(python系统自带python2.7，通过pyenv安装)
• 辅助工具：pyenv  virtualenv virtualenvwrapper

2、下载离线pytorch

https://download.pytorch.org/whl/torch_stable.html

https://download.pytorch.org/whl/cpu/torch-1.6.0-cp38-none-macosx_10_9_x86_64.whl

3、安装pyenv、virtualenv、virtualenvwrapper

---

pip install pyenv

或者：

git clone https://github.com/yyuu/pyenv.git ~/.pyenv

添加环境变量：

╭─nile@nilematoiMac ~/virtualenv_wk  
╰─$ vim ~/.zshrc

#pyenv
 
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
 

╭─nile@nilematoiMac ~/virtualenv_wk  
╰─$ source ~/.zshrc 

安装python3.8.5

由于官方源太慢，修改国内源

在3.8.5版本下安装

pyenv shell 3.8.5
pip install virtualenv -i https://mirrors.aliyun.com/pypi/simple/
pip install virtualenvwrapper -i https://mirrors.aliyun.com/pypi/simple/

source ~/.pyenv/versions/3.8.5/bin/virtualenvwrapper.sh

4、安装pytorch

 

pip install torch-1.6.0-cp38-none-macosx_10_9_x86_64.whl -i https://mirrors.aliyun.com/pypi/simple/

 

pip install torchvision -i https://mirrors.aliyun.com/pypi/simple/
