Launch script issues

[Paul Jerem]

Hi there,

I've successfully forked/installed Autopilot on MacOS 10.4.4/Python 3.8.5 (following the instructions here). Running the setup routine for a terminal agent also seemed to work fine, giving:

--------------------------------
Environment Configuration:
  [ SUCCESS ] virtualenv detected, path: /Users/pauljerem/.virtualenvs/autopilot

Additional Messages:  Launch file created at /Users/pauljerem/autopilot/launch_autopilot.sh
--------------------------------

(albeit with the following warning):

/usr/local/Cellar/python@3.8/3.8.5/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py:127: RuntimeWarning: 'autopilot.setup.setup_autopilot' found in sys.modules after import of package 'autopilot.setup', but prior to execution of 'autopilot.setup.setup_autopilot'; this may result in unpredictable behaviour
  warn(RuntimeWarning(msg))

However, when I try to run the launch script (sh launch_autopilot.sh), I get:

/Users/pauljerem/PycharmProjects/autopilot/autopilot/autopilot/core/terminal.py:251: DeprecationWarning: QDesktopWidget.availableGeometry(int screen) const is deprecated

Do you have any idea what the issue might be? I'm very much a Python novice (much more of an R user...), so please forgive me if I've just made a rookie error! :)

Thanks v. much,

Paul.

I think you need to set up and use an environment with python 3.7 instead of 3.8.

Haven't seen this one before, but yes there are some things that need to be fixed for a bump to 3.8 -- currently  the major thing holding back the bump is that the spinnaker camera drivers only support 3.7, but I think we should move to using Aravis to not have to rely on closed-source packages like that. If making a venv with 3.7 fixes the problem then good, but if not submit as an issue and i'll chase down. In the meantime have made requirement of 3.7.* more explicit here: https://github.com/wehr-lab/autopilot/commit/01543a9708d4bf06c74dc6af6fc7e8917331fc98

Thanks both - will try again with 3.7.
