Rendering problem with all Py scripts

[craiganderson-53546]

Thanks for the great code. I created a new Python 3.7 env on my Lenovo Yoga C930 running Win10. When loading the PyQt5 package it erred with "spyder 4.1.2 requires pyqtwebengine<5.13; python_version >= "3", which is not installed". The install with PyQt5 v5.14.1 succeeded with this error but Interactive.py acted very badly, no control via the GUI. I had to install PyQt5 5.12.2 to get rid of the errors. Interactive.py works better but all scripts act badly...

logistic_interactive.py - GUI is mostly correct but it only parts of the graphs appear. Populations updates live, but only bits and pieces of Bifurcations appears logistic_mandelbrot.py - GUI shows the Mandelbrot set but as soon as it starts rotating it zooms into a small section and freezes logistic_zoom.py - Draws the cobweb completely but does not zoom. It appears not to be frozen, but seems to be redrawing the cobweb rapidly

I see that vispy is GPU-accelerated. My Lenovo has the Intel GPU, not NVIDIA. Is that a possible cause. Are these possibly related to the PyQt5 lib version? Might you have any guidance on how to see the visualizations correctly?

vispy should work on any graphics card, since it uses OpenGL 2.0 which is available on everything from smartphones to toasters these days hehe :)

Your error seems to be pointing to the use of spyder 4.1.2 and the fact that you don't have pyqtwebengine?

Perhaps try running the commands directly from the console rather than inside of a Spyder environment?

Good to know on vispy

I have pyqtwebengine... here is the pip outpt... (py3.7_Chaos) c:\jupyter\Chaos-master>pip list | find "PyQtWebEngine" PyQtWebEngine 5.12.1

I did ran all scripts from the console. I assumed it used spyder since it reports the issues with its version.

Got any ideas?

Seems maybe you have PyQtWebEngine in a main environment but not in the py3.7_Chaos environment?

Are you still having this issue?
