Installing numpy for Windows 10: Failed to import numarray numpy extension module

I am new to Pythonand unsuccessfully numpyinstall numpy. Currently, the problem is reading the error message in particular Importing the multiarray numpy extension module failed. I can not find this error message on the Internet and ask for help. The full error message is at the bottom of this post.

At first I thought that I should provide information about the system and version and describe what I did. I use Windows 10on a 64 bit machine and installed Python 2.7.13from https://www.python.org/downloads/windows/

I also installed Anaconda, also for the Python 2.764-bit machine, downloaded here https://www.continuum.io/downloads . Anacondalaunches Python 2.7.12, not Python 2.7.13. When I type import numpyinside the AnacondaGUI IPythonno errors or warnings appear. However, I got the impression that running numpyfrom Python 2.7.13using IDLE (Python GUI)might be computationally faster. Python 2.7.13appears first in my Path statement.

I downloaded numpy-1.12.0rc2+mkl-cp27-cp27m-win_amd64.whlfrom http://www.lfd.uci.edu/~gohlke/pythonlibs/#jpype. The following suggestions from this post install numpy from wheel format on windows (wheel is not supported on this platform.) I renamed:

numpy-1.12.0rc2+mkl-cp27-cp27m-win_amd64.whl for: numpy-1.12.0rc2+mkl-cp27-none-win32.whl

, . C:\Python27

Windows (cmd), pip :

python -m pip install --upgrade pip

, pip .

cmd:

pip install numpy-1.12.0rc2+mkl-cp27-none-win32.whl

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.

I fixed this problem with the following steps:

  1. Create and activate a new environment conda
  2. Installation numpyin the environment
  3. Then using this environment for my project

I used PyCharmto execute (3), I just set the project interpreter equal to the Python interpreter in the new environment that I created in (1).
