Peter,

This is a known issue for the v1.1.2 windows installation.  I hope to have to resolved for the next release which will be shortly after the impending 3.7.11 release.

Swartz,

So it is clearly fftpack loading issue. Make sure that all your lib versions are correct (32/64 bit) and other math lib dependencies for fftpack is satisfied on your windows version.

Hi Swartz,

I have never tested gr_filter_design in windows. That said, can you please test whether the following imports work in your windows python shell / as a standalone python script.

>>import scipy
>>from scipy import fftpack, poly1d, signal

I have GNU radio v3.7.10.1/v1.1.2 installed from http://www.gcndevelopment.com/gnuradio/downloads.htm on my Windows 7 machine.  I am using USRP B200 as well.  When I try to run gr_filter_design from the command prompt, I get a SciPi not installed error.  I have verified that SciPi is installed.  I know this would work on a Linux box, but I want to know how to get gr_filter_design.py to import SciPi on Windows 7.
