[Discuss-gnuradio] gr_filter_design issue

[sreeraj r]

Hi,

I just noticed that "gr_filter_design" is throwing numpy error and fails to start (with latest gnuradio-git).  I could atleast find one more guy complaining about this (http://stackoverflow.com/questions/25882030/gnuradio-filter-design-tool/26142876#26142876).

The issue in my case was with

>> from PyQt4.Qwt5.anynumpy import *  (line no 25 in polezero_plot.py).

Code works fine if I replace the above line with

>>from numpy import zeros
>>from numpy import float as Float

Anyone else facing the same issue or is this only with my Qt4 package? (just launch "filter-design" tool from GRC and try playing with pole-zero plot)

Thanks
