I am using windows 7 home basic 64 bit. I wanted to work with FITS file in python 3.3 so downloaded pyfits and numpy for 64 bit. When I import pyfits I get the following error:

Traceback (most recent call last): File "", line 1, in import pyfits as py File "C:\Python33\lib\site-packages\pyfits__init__.py", line 26, in import pyfits.core File "C:\Python33\lib\site-packages\pyfits\core.py", line 38, in

Did you check that you have the correct Numpy installed for your platform? – Iguananaut

This is a problem importing numpy, not pyfits. You can tell because the traceback ended upon trying to import the numpy multiarray module.

This error suggests that the numpy you have installed was not built for the same architecture as your Python installation.

I'd highly recommend checking out the Enthought python distribution (Canopy), which comes nicely prepackaged with pyfits, numpy, scipy, matplotlib, and a whole mess of other modules. They have binaries which should run out of the box for Windows. https://www.enthought.com/products/canopy/
