安装了anaconda3，自带numpy库，但不能导入

Question

    ImportError                               Traceback (most recent call last)

During handling of the above exception, another exception occurred:

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: cannot import name 'multiarray'

问题补充：1.我已经在网上搜索了的问题，有人说需要卸载numpy库后重新装，试了但不管用，同时，我又重装了anaconda，也不管用。
2.我的电脑上还同时安装了独立的python3,python2。python3是默认系统。

试试从这里https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy 下载到本地, 用pip install 下载文件路径 方式安装,
同时,试试numpy‑1.14.1+mkl‑cp35‑cp35m‑win_amd64.whl 这种带mkl的和不带mkl的:
还有这句话: Many binaries depend on numpy-1.13+mkl and the Microsoft Visual C++ 2008 (x64, x86, and SP1 for CPython 2.7), Visual C++ 2010 (x64, x86, for CPython 3.4), or the Visual C++ 2017 (x64 or x86 for CPython 3.5, 3.6, and 3.7) redistributable packages.
