Importing the multiarray numpy extension module failed

环境信息：win10操作系统，python3.6 64bit.

安装Tensorflow:python -m pip install --upgrade tensorflow-gpu，执行成功。

import tensorflow报错：

from matplotlib import pylab

ImportError:

Importing the multiarray numpy extension module failed.  Most

likely you are trying to import a failed build of numpy.

If you're working with a numpy git repo, try `git clean -xdf` (removes all

files not under version control).  Otherwise reinstall numpy.
Original error was: DLL load failed: 找不到指定的程序。

分析了下，是import numpy出问题了。
直接import numpy都有问题：

import numpy
