MacOS 安裝 TensorFlow2.1.0

環境：

Mac  10.15.3 (19D76)

Python 3.6.8：https://www.python.org/ftp/python/3.6.8/python-3.6.8-macosx10.9.pkg

TensorFlow: 2.1.0

 

1.下載安裝Python安裝包，打開pkg並安裝。

wget -i -c https://www.python.org/ftp/python/3.6.8/python-3.6.8-macosx10.9.pkg

 

2.進入安裝目錄。設置軟件源、升級pip

cd /Library/Frameworks/Python.framework/Versions/3.6/bin
./pip3 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
./pip3 install pip -U

 

3.升級setuptools工具，因為安裝tensorflow一些包需要最新版本

./pip3 install --upgrade setuptools

 

4. 查詢可以安裝的TensorFlow版本

cd /Library/Frameworks/Python.framework/Versions/3.6/bin
./pip3 search tensorflow

➜  / pip3 search tensorflow
tensorflow (2.1.0)                                - TensorFlow is an open source machine learning framework for everyone.
tensorflow-qndex (0.0.22)                         - tensorflow-qnd x tensorflow-extenteten
tensorflow-plot (0.3.2)                           - TensorFlow Plot

 

5.指定安裝tensorflow2.1.0

./pip3 install tensorflow==2.1.0

期間可能會有版本依賴或版本太低，導致無法安裝，根據提示安裝依賴庫即可。如 ./pip3 install h5py 

 

6.驗證安裝是否成功

➜  bin ./python3
