macOS M1安装miniconda和基本使用

安装

• 1. 下载安装包
     download
• 2. 修改刚刚下载的安装包权限

chomod 777 Miniconda3-latest-MacOSX-arm64.sh

• 3. 执行安装

./Miniconda3-latest-MacOSX-arm64.sh

• 4. 一路回车，如果遇到需要填写yes/no的填yes

基本使用

• 1. 创建环境

 conda create -n sp3.9 python=3.9

• 2. 切入环境

source activate sp3.9

• 3. 安装包

 pip install torch

在系统层面的python安装失败的包，在conda环境依旧没有成功，不知道这个和M1 芯片是否有关系

下面这个包是为了安装一个github 开源图像库所需要的依赖，参考：https://www.jianshu.com/p/bd6b24380d68

pip install basicsr

M1芯片就python的相关依赖而言，很多都无法安装，用了不到三个月，在折腾环境安装东西这块累计浪费的时间差不多有150小时，而且结果都是没有解决。

M1 芯片对于图像，和pycurl 都不是能很好的支持（不支持），其中图像比如GFPGAN，paddle，

但是好像也有解决方案， 比如这里
https://github.com/PaddlePaddle/Paddle/issues/32377
https://github.com/conda-forge/miniforge/issues/165
conda环境利用rosseta来实现模拟Intel芯片，这样架构就切换成了X86

CONDA_SUBDIR=osx-64 conda create -n rosetta python   # create a new environment called rosetta with intel packages.
conda activate rosetta
python -c "import platform;print(platform.machine())"
conda config --env --set subdir osx-64  # make sure that conda commands in this environment use intel packages

CONDA_SUBDIR=osx-64 conda create -n pd_rosetta python // create a new environment called pd_rosetta with intel packages.
conda activate pd_rosetta
python -c "import platform;print(platform.machine())"  // should be ‘x86_64’ not ‘arm64’
conda env config vars set CONDA_SUBDIR=osx-64 // # make sure that conda commands in this environment use intel packages
conda deactivate
conda activate pd_rosetta
echo "CONDA_SUBDIR: $CONDA_SUBDIR"
python -m pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

通过模拟x86的环境，解决了上面的报错

rosetta3

查看当前环境的cpu架构

python -c "import platform;print(platform.architecture()[0]);print(platform.machine())"
