Hi,

I downloaded & properly installed JetBrains PyCharm (pycharm-community-2016.3) & Python (python-3.6.0b4-amd64)

Now I tried to install NumPy using command:

cmd > python -m pip install numpy

But I'm getting an error.

--

I also downloaded various wheels.
But it says "Not a supported wheel" for numpy-1.12.0rc1-cp27-none-win_amd64, numpy-1.12.0rc1-cp34-none-win32 & numpy-1.12.0rc1-cp35-none-win32

Please help me out.
I don't think that NumPy for Python 3.6 is out. Try with 3.5

Or try to install it manually.

C:\Python36\pip.exe install C:\downloaded\numpy.whl

You have to replace all this with exact paths to a pip.exe and the downloaded numpy wheel file
Get your wheel from here. http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
Note naming convention so you get the proper wheel for your version of python and os
then from a command window, change directory to wheel location and run pip install wheelname

This site has a reputation for wheels that work first time, and they already
have wheels for 3.6
It also seems you are using release candidates for Python and Numpy. If you are on a windows 64 bit machine, you should have downloaded, for example: python-3.6.0-amd64.exe, the file name you are showing is for a beta release. The same is true for Numpy, the extension "1.12.0rc1-cp27" shows it is a release candidate for Python 2.7
the other shows a release candidate for Python 3.5 64 bit.   Again, if you are on a 64 bit machine, you want the file "numpy-1.11.3+mkl-cp36-cp36m-win_amd64.whl" from the site referenced by Larz60+
