[Discuss-gnuradio] FW: Error when executing gr-Inspector block

 

Im trying to follow this-> https://github.com/gnuradio/gr-inspector/tree/master so as to work with gr-inspector blocks.

I have cross checked every dependency mentioned in the project.Installation is successful without any error.

But executing any flowgraph including signal_detector block gives m the following error->
   
    self.inspector_qtgui_sink_vf_0 = Template error: #set $win = 'self._%s_win'%$id
    SyntaxError: invalid syntax

Attaching the flow graph im trying to execute.

Looking for quick reply :)
