MacOS+miniconda+theano安装

Posted 2021-03-26 pocahontas

1. brew update --debug --verbose

2. brew install wget

3. xcode-select --install

4. 以上都不行

   Error: No such file or directory @ dir_chdir - /usr/local/Cellar

    

   卸载重装homwbrew
   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 
   这样，在最新的HomeBrew中，安装的时候就将需要的目录都已经创建完成并且分配了所需的权限，那么在用brew去安装其他软件的时候就可以不需要sudo权限直接进行了

5. 替换核心软件仓库

   cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
   git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
   替换 cask 软件仓库（提供 macOS 应用和大型二进制文件）

   cd "$(brew --repo)"/Library/Taps/caskroom/homebrew-cask
   git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
   替换 Bottles 源（Homebrew 预编译二进制软件包）

   bash（默认 shell）用户：

   echo ‘export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles‘ >> ~/.bash_profile
   source ~/.bash_profile

6. brew install wget
   
   
7. https://docs.conda.io/en/latest/miniconda.html找到合适版本; cd ~

8. wget https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh

9. bash Miniconda3-latest-MacOSX-x86_64.sh
   
   Miniconda3 will now be installed into this location:

10. /Users/jingyuli/miniconda3.

11. 手动加载环境变量来使得conda生效.  source ~/.bash_profile
12. conda -h. 检验安装成功

 

 

接下来theano

• conda create -n theano python=3.5
• conda-env list
• source activate theano

Install requirements and optional packages

• conda install numpy scipy mkl nose sphinx
• pip install parameterized

Install and configure the GPU drivers (recommended) CUDA安装

macbookpro没有英伟达显卡 不支持gpu
