[Discuss-gnuradio] wx-scope

[Michael Hartje]

dear list,

after installing the new Gnuradio-Companion  there is no function in
wx-scope (qt-scope works)

GNU Radio Companion 3.7.12git-295-ga0adcd33 (installed via pybombs)
pybombs version 2.3.2
ubuntu 16.04.3 LTS

Python 2.7 and 3.5 (standard -- calling python -- is 2.7)

GRC-Example:

a simple tone generator ,throttle and wx scope sink

--> does not work:

I got repetitive error lines until stopping the running
tone-example-program:

Starting the program shows:

Generating: '/home/hartje/Dokumente/sdr/grc/tone_simple.py'

Executing: /usr/bin/python2 -u /home/hartje/Dokumente/sdr/grc/tone_simple.py

and then the repeated line

--------

ambiguous. Use a.any() or a.all()

line 211, in draw
    if coord == None:
ValueError: The truth value of an array with more than one element is

---------------

the wx fft-plot works without any problems, wx-Instrumentation works as
expected

How can I get wx-scope to work properly?

former (older) installations of GRC do work as expected (scope)

Any help appreciated

Thanks in advance
