What are you using to install Pandas/Numpy? – Hitesh Dharamdasani
Windows is the red-headed stepchild of coding environments (unless you're using .Net or other Windows-only stuff). I'd recommend going here and downloading a binary. Installing Python libraries in Windows that require compiling C or C++ code is a level of hell. – user554546
Although if you want to continue, you'll also need to install LAPACK (which probably means compiling that from source. In Windows. Have fun with that.) – user554546
I installed Visual C++ and then tried easy_install numpy but i got following error: – Rajat Nigam

EDIT 3: BEST WAY see if you have pip, if not, it is easy to install open up cmd.exe type 

python -m pip install numpy

Try using this installer for numpy from the repository http://www.lfd.uci.edu/~gohlke/pythonlibs/

http://www.lfd.uci.edu/~gohlke/pythonlibs/girnt9fk/numpy-MKL-1.9.1.win32-py2.7.exe

and see if you return errors there

EDIT: There are two major errors here

  1. is a problem with the setup.py (or at least easy-install)

    either the script is the problem (can't find files in the directory)

    or the directory downloaded was flawed

    Atlas, Blas, Blassrc, and Lapack sources cannot be found because the

script never found numpy\distutils\site.cfg that would point to these. To fix

this problem Rajat would have to edit the script setup.py and fix the

directory location for site.cfg

  1. Rajat may not have the right version of Microsoft Visual C++(2008), he can check

it using a variety of methods, but it wouldn't hurt to download

separately, Rajat can get it from here http://www.microsoft.com/en-us/download/details.aspx?id=29

ALTERNATIVELY, it is likely the exe will work out of box, as someone who

sometimes uses Windows to write python, .exes and .msis are the first thing

I look for, because they have always given the least headaches for me if

they exist

EDIT 2:

I downloaded numpy 1.9.1.zip, in the instructions it says you have to build YOUR OWN site.cfg file. there is more information in a file called site.cfg.example (you can open it with a text editor like Notepad ++, Gedit, &c). From what I understand the the only contents need to be 

    library_dirs=c:\mingw\lib,c:\atlas\lib

for this to work, you need to download the mingw package, you can get that from here:

http://sourceforge.net/projects/mingw/files/

and you need Atlas, the instructions to install that are here

http://math-atlas.sourceforge.net/atlas_install/node50.html

make sure these folders go to C:\ or change the directory in site.cfg

the site.cfg you write in a text editor needs to be in PATHTONUMPY-1.9.1/numpy/distutils/

I HIGHLY recommend trying the .exe I've linked. but try these and update if there are more errors

In these cases I recommend using a Python distribution from other vendors who take care of providing complex packages built for Windows. Seriously, have a look at for instance https://www.activestate.com/activepython/downloads. It's free to use without limitations (as long as you do not sell it), it comes with a good installer and it comes with a package manager, where you can just type pypm install numpy and pypm install pandas.

The main advantage of this method is that it is super fast to re-create your Python environment of choice on any given Windows machine.

There is no disadvantage with such a Python installation, you can still use pip and all other package installation methods you are used to.

Installing pandas via the Anaconda package is the easiest way I've found:http://continuum.io/downloads This installer includes all the dependencies in one streamlined, contained install. I highly recommend it.
