Xcode
从 App Store 安装 Xcode。
image
Command Line Tools
从 Apple Developer 下载安装 Xcode Command Line Tools 或者执行以下命令。
$ xcode-select --install
Homebrew
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Miniforge
Anaconda 无法在 M1 上运行, Miniforge 是用来替代它的。
从 https://github.com/conda-forge/miniforge 下载 Miniforge3-MacOSX-arm64。
image
执行以下命令，安装 Miniforge
$ bash Miniforge3-MacOSX-arm64.sh
重启终端并检查 Python 安装情况。
$ which python
/Users/catchzeng/miniforge3/bin/python
$ which pip
/Users/catchzeng/miniforge3/bin/pip
下载 Apple TensorFlow
从 https://github.com/apple/tensorflow_macos/releases 下载 TensorFlow 并解压，然后进入 arm64 目录下。

创建虚拟环境
创建一个 conda 创建虚拟环境，这里使用 python 3.8 (ATF 2.4 需要)。
$ conda create -n tensorflow python=3.8
$ conda activate tensorflow
安装必须的包
$ brew install libjpeg
$ conda install -y pandas matplotlib scikit-learn jupyterlab
注意: libjpeg 是 matplotlib 需要依赖的库。
安装特殊版本的 pip 和其他包
$ pip install --force pip==20.2.4 wheel setuptools cached-property six packaging
注意: Apple TensorFlow 特殊版本的 pip。
安装 Apple 提供的包(numpy, grpcio, h5py)
$ pip install --upgrade --no-dependencies --force numpy-1.18.5-cp38-cp38-macosx_11_0_arm64.whl grpcio-1.33.2-cp38-cp38-macosx_11_0_arm64.whl h5py-2.10.0-cp38-cp38-macosx_11_0_arm64.whl
安装额外的包
$ pip install absl-py astunparse flatbuffers gast google_pasta keras_preprocessing opt_einsum protobuf tensorflow_estimator termcolor typing_extensions wrapt wheel tensorboard typeguard
安装 TensorFlow
$ pip install --upgrade --no-dependencies --force tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl
$ pip install --upgrade --no-dependencies --force
tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl
最后，升级 pip 到正确的版本。
$ pip install --upgrade pip
测试
TensorFlow
$ python
Python 3.8.8 | packaged by conda-forge | (default, Feb 20 2021, 15:50:57)
