I'm not familiar with visPy. My assumption is that there is a dependency
for VisPy that Pyinstaller can not detect.
Is there a dependency of VisPy or a selectable "backend" for VisPy?
If so look at importing the these dependencies into your main.py so
pyinstaller can see them, or add to the hidden-imports list in pyinstaller.
