Segmentation Fault in rviz_python_tutorial/myviz.py #46

Closed ProgenitorX closed 6 years ago

ProgenitorX commented 6 years ago

I'm getting a Segmentation Fault (core dumped) whenever I try to run myviz.py.

I've done roscd rviz_python_tutorial followed by rosrun rviz_python_tutorial myviz.py I've also tried simply python myviz.py

The problem happens on line 58: self.frame.initialize() Debugger shows self.frame is an instance of librviz_sip.VisualizationFrame object, as expected.

I'm using Python 2.7.12 and PyQt5 5.5.1 I believe everything should be set up properly (dir under catkin_ws/src and catkin_make succeeded).

Here is the gbd backtrace:

Thanks! Let me know if I can provide anything else that might be of use.

Turns out 3D Acceleration was on somehow for my VBox, causing a Seg Fault for RViz. Sorry for the trouble and thanks for the tutorials!
