How to install GDAL/scipy using cmd in window?
Question: I downloaded `scipy-0.17.0-cp27-none-win_amd64.whl` and
`GDAL-1.11.4-cp27-none-win_amd64.whl` from
[gohlke](http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy) in
**C:\Python27\Scripts**

To install I used

`pip install scipy-0.17.0-cp27-none-win_amd64.whl pip install
GDAL-1.11.4-cp27-none-win_amd64.whl`

It says the installation is complete but when I import the libraries as

    
    
    import scipy
    import gdal
    

it shows error as

> No module named gdal  
>  No module named gdal

However, I installed the `matplotlib`, `numpy` in the very same way and they
are working absolutely fine.


Answer: I solved this problem eventually to found the mistake in my approach. This
problem can occur with anyone using ArcGIS in one's system.

ArcGIS comes with it's default Python package and if one installs python
separately, each time the new libraries gets installed in the newer Python
installation not in ArcGIS.

Therefore, the pyhton IDLE which one uses need to be from another Python
installation. Here in my case, ArcGIS has Python 2.6 and I have made an
separate installation using Python 2.7.11.

All the libraries were getting installed in right place but I was opening the
wrong IDLE to write scripts hence getting error.
