环境:
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.下载安装Python安装包,打开pkg并安装。
wget -i -c https://www.python.org/ftp/python/3.6.8/python-3.6.8-macosx10.9.pkg
2.进入安装目录。设置软件源、升级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.升级setuptools工具,因为安装tensorflow一些包需要最新版本
./pip3 install --upgrade setuptools
4. 查询可以安装的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.指定安装tensorflow2.1.0
./pip3 install tensorflow==2.1.0
期间可能会有版本依赖或版本太低,导致无法安装,根据提示安装依赖库即可。如 ./pip3 install h5py
6.验证安装是否成功
