执行“导入 tensorflow”时出错（Tensorflow 安装错误 Windows 10）

Question

执行“导入 tensorflow”时出错（Tensorflow 安装错误 Windows 10）： 通过在命令提示符下键入 pip3 install tensorflow 成功安装。 （我同时安装了 Python 2.7.11 和 Python 3.5.2，但我正在为 Python 3 安装 tensorflow（使用 pip3））。它是 CPU 安装，而不是 GPU 安装。当我尝试执行“import tensorflow”时，出现以下错误。我也检查了 DLL 文件。 C:\Windows\SysWOW64\MSVCP140.DLL 文件存在。请帮忙。

Traceback (most recent call last):

在处理上述异常的过程中，又发生了一个异常：

现在解决了！

我必须从here 下载并安装 Visual C++ 2015 可再发行（x64 版本）文件，然后重新启动我的机器。
