无法在 Windows 7 上导入张量流

Question

编辑：在 user1735003 对 tensforflow 文档如何明确声明它仅支持 Windows 上的 Python 3.5.x 发表评论后，我删除了早期的 3.6.2 版本并安装了 3.5.2 而不是。不过，我得到了同样的错误。

我有一个 Windows 7 Professional x64，使用 Python 3.5.2。当我尝试导入 tensorflow 时，出现以下错误：

   Traceback (most recent call last):

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

Python 安装在：C:\Users\Ritwik\AppData\Local\Programs\Python\Python35\python.exe

我已经按照documentation 中的建议使用 pip 安装了 tensorflow。

pip3 install --upgrade tensorflow

我没有 NVIDIA GPU。

来自documentation：

TensorFlow 仅支持 Windows 上的 Python 3.5.x 版本。
