笔者投入 M1 的怀抱曾经有一段时间了，俗话说得好，但闻新人笑，不见旧人哭，Intel mac 早已被束之高阁，而 M1 mac 曾经不能用真香来形容了，几乎就是“香透满堂金玉彩，扇遮半面桃花开！”，轻抚 M1 mac 那滑若柔荑的秒控键盘，别说 996 了，就是 007，咱们也能安之若素，也能够笑慰平生。好了，日常吹 M1 的环节完结，正所谓剑虽利, 不厉一直，材虽美，不学不高。本次咱们尝试在 M1 Mac os 中搭建 Python3 的开发环境。
个别状况下，间接 Python 官网 (python.org) 下载最新的基于 arm 架构的 python3.9 即可，然而因为向下兼容等问题，咱们尝试应用 Python 多版本管理软件 conda，conda 在业界有三大巨头别离是:Anaconda、Miniconda 以及 Condaforge，尽管都放出音讯要适配 M1 芯片，然而目前最先放出稳定版的是 Condaforge，进入下载页面：https://github.com/conda-forg… 抉择 mac arm64 位架构:
该文件并不是安装包，而是一个 shell 脚本，下载胜利后，进入命令行目录:
cd ~/Downloas执行命令进行装置：
sudo bash ./Miniforge3-MacOSX-arm64.sh随后会有一些条款须要确认，这里按回车之后键入 yes:

client_ssl_cert: None其余的一些 conda 常用命令：
1. conda –version #查看 conda 版本，验证是否装置
2. conda update conda #更新至最新版本，也会更新其它相干包
3. conda update –all #更新所有包
4. conda update package\_name #更新指定的包
5. conda create -n env\_name package\_name #创立名为 env\_name 的新环境，并在该环境下装置名为 package\_name 的包，能够指定新环境的版本号，例如：conda create -n python2 python=python2.7 numpy pandas，创立了 python2 环境，python 版本为 2.7，同时还装置了 numpy pandas 包
6. source activate env\_name #切换至 env\_name 环境
7. source deactivate #退出环境
8. conda info -e #显示所有曾经创立的环境
9. conda create –name new\_env\_name –clone old\_env\_name #复制 old\_env\_name 为 new\_env\_name
10. conda remove –name env\_name –all #删除环境
11. conda list #查看所有曾经装置的包
12. conda install package\_name #在以后环境中安装包
13. conda install –name env\_name package\_name #在指定环境中安装包
14. conda remove — name env\_name package #删除指定环境中的包
15. conda remove package #删除以后环境中的包
16. conda create -n tensorflow\_env tensorflow
conda activate tensorflow\_env #conda 装置 tensorflow 的 CPU 版本
17. conda create -n tensorflow\_gpuenv tensorflow-gpu
conda activate tensorflow\_gpuenv #conda 装置 tensorflow 的 GPU 版本
18. conda env remove -n env\_name #采纳第 10 条的办法删除环境失败时，可采纳这种办法
接着咱们来尝试集成深度学习框架 Tensorflow，因为目前默认是 3.9，咱们应用 conda 创立一个 3.8 的虚构开发环境：
sudo conda create -n py38 python=3.8装置胜利后，输出命令：
conda info -e就能够查看以后 conda 装置的所有版本：
➜ ~ conda info -e
# conda environments:
#
base * /Users/liuyue/miniforge3
py38 /Users/liuyue/miniforge3/envs/py38能够看到一个默认的 3.9 环境，和新装的 3.8 环境，星号代表以后所处的环境，这里咱们切换到 3.8：
conda activate py38此时环境曾经切换到 3.8：
(py38) ➜ ~ conda activate py38
(py38) ➜ ~ conda info -e
# conda environments:
#
base /Users/liuyue/miniforge3
py38 * /Users/liuyue/miniforge3/envs/py38
(py38) ➜ ~上面开启深度学习框架 Tensorflow 之旅，因为苹果对 m1 芯片独自做了适配，所以不能用以前的 pip 形式间接进行装置，须要独自下载文件：https://github.91chifun.worke…://github.com/apple/tensorflow\_macos/releases/download/v0.1alpha1/tensorflow\_macos-0.1alpha1.tar.gz
解压文件：
tar -zxvf tensorflow_macos-0.1alpha1.tar.gz解压后进入目录(肯定要进入 arm64 的文件内)：
cd tensorflow_macos/arm64执行命令利用下载的 arm64 内核安装包进行装置：
pip install --force pip==20.2.4 wheel setuptools cached-property six

[('打招呼', '0.998965')]霎时执行结束，秒杀 intel 芯片的 mac，怎一个香字了得！
接下来，尝试装置另外一个在业界名声煊赫的深度学习框架 Pytorch！
因为以后 arm64 架构的只反对 3.9 版本，所以咱们来创立一个虚拟空间：
sudo conda create -n pytorch numpy matplotlib pandas python=3.9这里提前将须要的根底库都一一装置，因为如果不在创立虚拟空间时提前装置，之后应用 pip 是装置不上的，装置胜利后，激活环境：
(pytorch) ➜ conda activate pytorch
(pytorch) ➜随后下载 arm64 版本的 pytorch 安装包：https://github.com/wizyoung/A…\_11\_0\_arm64.whl
下载胜利后，执行装置命令：
sudo pip install torch-1.8.0a0-cp39-cp39-macosx_11_0_arm64.whl让咱们来试试 Pytorch 在 M1 芯片加持后的性能，编写 test\_torch.py:
from tqdm import tqdm
import torch
@torch.jit.script
def foo():
x = torch.ones((1024 * 12, 1024 * 12), dtype=torch.float32)
y = torch.ones((1024 * 12, 1024 * 12), dtype=torch.float32)
z = x + y
return z
if __name__ == '__main__':
z0 = None
for _ in tqdm(range(10000000000)):
zz = foo()
if z0 is None:
z0 = zz
else:
z0 += zz后果仍然秒杀 Intel mac，达到了 320 it/s，你敢信？
最初，有没有 arm64 架构的编辑器呢？答案是有的，vscode 值得领有，下载地址：https://code.visualstudio.com… 肯定要抉择 arm64 版的：
解压后间接运行即可，能够在插件商店抉择 Python 和 Code Runner，即可开启 M1 的 Python 代码编写之旅。
结语：M1 芯片的 Mac 和 Python3，几乎就是金风玉露，绝配天成。只有撩开 M1 和开发者们之间的那一层帷幔，期待咱们的，就是纵享丝滑的开发感触，还等什么？犹豫只会败北，是时候焚烧灵魂，献出钱包了。
