MAC笔记安装Pytorch 环境安装

1. 安装brew

方法1 参考： https://www.jianshu.com/p/e0471aa6672d?utm_campaign=hugo

使用中科大镜像加速访问：

/usr/bin/ruby -e "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install)"

参考： https://zhuanlan.zhihu.com/p/90508170
实测执行如下代码：

(base) MacBook-Pro:resume yinfufeng$ /bin/bash -c "$(curl -fsSL https://gitee.com/ineo6/homebrew-install/raw/master/install.sh)"

设置清华源：

git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

brew update

2. 安装Anaconda

[1] 添加Anaconda的TUNA镜像

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

[2]设置搜索时显示通道地址

conda config --set show_channel_urls yes

[3] 安装anaconda

curl -O https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-x86_64.sh
sh Miniconda3-latest-MacOSX-x86_64.sh

##3. 安装pytortch
1）设置Python版本为3.9版本，创建pytorch环境

(base) MacBook-Pro:DeepLab fyf$ conda create -n pytorch_py39_env python=3.9

2）安装pytorch包
参考 https://pytorch.org/get-started/locally/

• [1] 激活环境

(base) MacBook-Pro:DeepLab fyf$ conda activate pytorch_py39_env
(pytorch_py39_env) MacBook-Pro:DeepLab yinfufeng$

• [2]安装依赖数据包

conda install pytorch torchvision torchaudio -c pytorch

• [3] 退出环境:

$ conda deactivate

3. notebook
   安装jupyter notebook后，执行命令:

jupyter notebook
