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
--------
ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()
Traceback (most recent call last):

legendTextExt)

line 1206, in _drawLegend
o.draw(dc, self.printerScale, coord= _numpy.array([pnt1,pnt2]))
File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plot.py",
line 211, in draw
if coord == None:
ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()
---------------
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
