The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than right now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

Not sure what the cause of this one is. Works fine on my end. If you want you could try opening up the python console in Blender and run

import sys
import os

os.system(f"{sys.executable} -m pip install opencv-python")

wait for it to finish & then try activating the addon again. This shouldnt be necessary though because my addon does something similar on its own to prevent this error from happening. Make sure you have an internet connection available as were installing open-cv via pythons package manager (over the internet)

Theres a similar issue however where it will complain about "ModuleNotFoundError: No module named 'fast'" in 1.7.0, for this one you simply have to activate the addon a second time. I intend to patch this in the future because having to activate it twice isnt a very nice workaround 😅This one is causd by me trying to modify sys.path - and it seems the changes doesnt take effect immediately for some reason (so I will need to figure out a different solution, or somehow have the addon restart itself upon activation after having modified sys.path ).
