5.0.0 dpkg on pi ValueError: bad marshal data (unknown type code)

[vince]

Probably a Matthew issue.....

On a pi5 arm64 raspios running v5.0.0 weewx dpkg and using the WeatherFlowUDP driver vs. my UDP simulator, I'm seeing the following.....only the Seasons skin is enabled.

I tried deleting all weewx-related .pyc files everywhere but it didn't help.

Note - a pip install on top of the same os does 'not' show any problems at all so this might be a problem with the precompiling the dpkg does if you run it on 64bit (perhaps)....

a few things to check:

- delete the .pyc files and the __pycache__ directories that contain them

- be sure to delete the .pyc files and __pycache__ in the 'user' directory too

- check ownership - did you really delete the files?  does the user who will run weewx have permission to write the new pyc/__pycache__?

- be sure you are using consistent python - for example, remember that python3 and python3.9 may or may not be the same thing

Reflashed the os and started over and could not recreate this one.   Guessing I missed deleting a .pyc file earlier someplace under the hood.

So thanks and nevermind :-)
