I just recently installed Gr-Inspector and when I try to run a flow graph I get the error below.
/usr/local/lib/python2.7/dist-packages/gnuradio/grc/gui/ActionHandler.py:78: Warning: Source ID 403 was not found when attempting to remove it
/usr/local/lib/python2.7/dist-packages/gnuradio/grc/gui/BlockTreeWindow.py:221: Warning: Source ID 411 was not found when attempting to remove it
*** Error in `/usr/bin/python2': double free or corruption (!prev): 0x0000000002320520 ***
Not quite sure but I think when installed tensorflow that it may have changed my python install and possibly caused this error. Hopefully someone can provide some feedback.
