Install TensorFlow 2 for Windows 10

Windows  python是3.9版本的，先安装试试，看看会有什么问题？

1.升级pip，2个警告，先不管

2.安装下面3个

pip3 install six numpy wheel
pip3 install keras_applications==1.0.6 --no-deps
pip3 install keras_preprocessing==1.0.5 --no-deps

看 提示，貌似只可以安装到python3.8上面，python3.9 不支持哦。还是有警告

需要安装 msys2

第一步：安装MSYS2 shell，下载后，直接双击，点击安装，可自定义安装路径。

 

第二步：配置环境变量，在电脑-高级-环境变量中的path中添加“你的根目录\msys64\usr\bin”和“你的根目录\msys64\usr\bin\bash.exe”

 

第三步：打开cmd,输入pacman -Syu，回车会出现下图，然后输入y 安装失败

太高版本bazel 还安装不了，需要重新下载

https://github.com/bazelbuild/bazel/releases/tag/3.7.2

You have bazel 4.0.0 installed.
Please downgrade your bazel installation to version 3.99.0 or lower to build TensorFlow! To downgrade: download the installer for the old version (from https://github.com/bazelbuild/bazel/releases) then run the installer.
