MacOS M1 安裝tensorflow

通過miniforge安裝tensorflow

1. 安裝miniforge:

• 如果已有anaconda可以先卸載

# 刪除conda環境
rm -rf ~/miniforge3
rm -rf .conda
rm -rf .condarc

• 安裝miniforge
  • github鏈接，直接下載【OS X， arm64 (Apple Silicon)】：https://github.com/conda-forge/miniforge/#download

# 執行以下內容
bash Miniforge3-MacOSX-arm64.sh

• 配置yml安裝依賴文件

  name: apple_tensorflow
  channels:
    - conda-forge
    - nodefaults
  dependencies:
    - grpcio
    - h5py
    - ipython
    - numpy
    - pip=20.2.4
    - python=3.8
    - scipy
    - termcolor
    - typeguard
    - wheel
    - absl-py
    - astunparse
    - python-flatbuffers
    - gast
    - google-pasta
    - keras-preprocessing
    - opt_einsum
    - protobuf
    - tensorboard
    - tensorflow-estimator
    - termcolor
    - typing_extensions
    - wrapt

• 創建conda環境

conda env create --file=PATH_TO_ENVIRONMENT.YML --name=YOUR_ENV_NAME
# 激活
conda activate YOUR_ENV_NAME

• 安裝tensorflow

pip install --upgrade --force --no-dependencies https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl

蘋果官方（macos 12+安裝方法, 2.5不行可以試試2.6）https://developer.apple.com/metal/tensorflow-plugin/

系統版本：https://zhuanlan.zhihu.com/p/386164537
找不到tensorflow-macos或者metal的情況下，這樣安裝 https://developer.apple.com/forums/thread/683757

問題：

1. 依賴沖突，可以帶上參數：pip install tensorflow-macos --force --no-dependencies
2. AlreadyExistsError（tensorflow 2.6.0）：錯誤原因是因為tensorflow和keras版本不匹配，運行pip install keras==2.6.0 可解決問題
3. 找不到各種方法，可以查看tensorflow 官方api: https://www.tensorflow.org/versions

卸載conda
