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 Sreeraj Rajendran
