Request to update to newer version of Python

[jharsono]

Since python 3.7 is no longer supported, can you make the app compatible with newer versions of python and other dependencies? I haven't been able to run this on an Apple Silicon Mac.

I was able to get closer with Anaconda, setting my environment to x64 as suggested here, https://stackoverflow.com/questions/70205633/cannot-install-python-3-7-on-osx-arm64, and using Python 3.7.9

Here's the current error after running pip install -r requirements.txt successfully and python main_ocean.py:

Update again with a new error, so that's progress! I followed the steps here: https://stackoverflow.com/questions/63475461/unable-to-import-opengl-gl-in-python-on-macos

Now this is the message:

AttributeError: module 'cv2.aruco' has no attribute 'Dictionary_get'

Now I'm trying to work through this when I googled the issue: https://stackoverflow.com/questions/74964527/attributeerror-module-cv2-aruco-has-no-attribute-dictionary-get

[jharsono]

To the top of main_ocean.py I added

import faulthandler
faulthandler.enable()

to debug.

A segmentation fault occurs after instantiating SimpleScanner(). Since the fault handler didn't have any insight into that code, I pasted the simplescanner.py code at the top instead of importing. Here's latest:

@david-svitov any ideas?
