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

You should consider upgrading via the 'C:UsersdevAppDataLocalMicrosoftWindowsAppsPythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0python.exe -m pip install --upgrade pip' command.
2.安装下面3个
<code>pip3 install six numpy wheel</code> <code>pip3 install keras_applications==1.0.6 --no-deps</code> <code>pip3 install keras_preprocessing==1.0.5 --no-deps</code>
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msys64usrin”和“你的根目录msys64usrinash.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
